Stick and Arc Welding: The Complete Guide to SMAW, Electrodes, Safety, and Techniques

Picture a storm damaged farm gate with its only hinge snapped in two. With miles between the nearest repair shop and no access to shielding gas, the only option may be a small stick welder and a box of electrodes. It’s in moments like these, far away from a perfect shop, that the true value of stick and arc welding becomes apparent.

Introduction: What Are Stick and Arc Welding?

Before any beads are laid down, it’s important to answer the most fundamental question: what is stick welding? Simply put, stick welding is the common name for Shielded Metal Arc Welding (SMAW). It is one of the oldest, most rugged, and most widely recognized forms of electric welding still in use today.

The term “arc welding” itself is much broader. Arc welding is an umbrella term for any fusion welding process that uses an electric arc between an electrode and the base metal to generate enough heat to melt and join materials together. Stick welding is a specific type of arc welding, not the name for the entire family. The key distinction is the electrode itself: with SMAW, a flux coated, consumable metal rod, known as the “stick”, is used to both carry the current and provide its own shielding.

The Science Behind the Name

SMAW is classified as a fusion welding process that utilizes a flux coated consumable electrode to create the arc and shielding. When the electrode is struck against the workpiece, an electric arc forms between the tip of the rod and the metal. This arc can reach temperatures hot enough to melt both the end of the electrode and a portion of the base metal, forming a weld puddle. As this happens, the flux coating burns off and creates two critical forms of protection. The first is a shielding gas that displaces oxygen and nitrogen from the weld area. The second is molten slag, which floats on top of the puddle and solidifies to protect the cooling weld from the atmosphere. Once cooled, this slag must be chipped away to reveal the finished bead.

A History of Longevity

The roots of the process date back to the development of carbon arc welding in the late 1800s, however, the jump to flux coated electrodes is what truly made the process practical. By the early 20th century, coated rods allowed for cleaner, stronger welds than their bare predecessors. From there, its reliability allowed it to explode in popularity throughout shipbuilding, rail work, and heavy industry, and it never left. Decades later, even with the invention of gas shielded processes, the core principles of SMAW remain almost identical to the ones used generations ago.

Why It’s Still Heavily Used Today

Despite the rise of automated processes, SMAW remains one of the most utilized welding processes for repair and field work due to its portability and lack of required external shielding gas. A basic stick setup can be hauled to a remote job site with nothing more than a welder, leads, a chipping hammer, and a box of electrodes. This makes it ideal for farm repairs, structural steel fixes, pipeline maintenance, and emergency work where hauling a bulky tank of shielding gas simply isn’t an option.

Its versatility doesn’t stop at location either. With the correct rod selection, stick welding can tackle a wide variety of carbon steels, and for those looking to branch out into other materials down the road, understanding the differences between processes such as aluminum MIG welding can help showcase just how adaptable the welding trade truly is. Most importantly, the process is forgiving enough to be learned, yet challenging enough that mastery takes a lifetime. For a more in depth breakdown of these benefits, many welders take the time to review the advantages of stick welding to see why it still holds its ground against newer methods.

At its core, stick and arc welding are not relics of the past, but purpose built tools for the jobs that cannot wait for perfect shop conditions. With that foundation established, the rest of this guide will build upon it, starting with the science of the arc itself.

The Science of the Arc: How Stick Welding Works

Stick welding looks almost crude from the outside: a coated wire, a ground clamp, a flash of light, and a shower of sparks. Yet the moment the electrode touches the steel, a remarkably controlled chain of physics and chemistry begins. Understanding that chain is what separates a welder who guesses from a welder who predicts what the puddle will do. Once you know why the arc behaves the way it does, settings and technique stop being trial and error.

The Circuit and the Arc

Every SMAW setup is a simple electrical circuit. The power source feeds current through the electrode holder and the stick electrode, out at the arc, into the workpiece, and back along the work clamp and cable to the machine. When you drag the electrode tip across the plate, you create a momentary short circuit. As you lift it a small fraction of an inch, the gap ionizes and becomes plasma — a conductive channel of superheated gas that sustains the arc. That arc releases enough heat to melt both the electrode tip and the base metal beneath it, with temperatures commonly exceeding 6,000°F (roughly 3,500°C).

The arc is not a passive flame. It is a stream of electrons and ions that can be shaped by current, arc length, and electrode angle. Hold a long arc and the energy spreads, penetration drops, and spatter rises. Shorten it and the heat concentrates, which is why arc length is the first variable good welders control.

What the Flux Coating Actually Does

The flux coating is the reason a stick electrode can weld dirty, rusty, out-of-position steel when a bare wire cannot. It performs four jobs at once:

• Arc stabilization. Mineral additives such as potassium and sodium compounds ionize readily, keeping the arc from wandering or extinguishing, especially on AC.
• Atmospheric shielding. As the coating burns, it releases a gas envelope — largely carbon dioxide and its derivatives — that pushes oxygen and nitrogen away from the molten puddle.
• Alloying and deoxidation. Ingredients like ferromanganese and silicon clean the melt and fine-tune the chemistry of the deposited metal.
• Slag formation. The melted flux that doesn’t become gas floats as a liquid layer, then solidifies over the finished bead.

As the electrode melts, the steel core wire becomes the filler metal while part of the coating becomes shielding gas and the rest becomes that protective slag cover. Both halves of the electrode matter, which is why flux composition changes weld metal properties as much as wire chemistry does. If you want the same idea explored in a different process, our guide to aluminum flux welding shows how flux-covered filler behaves outside of carbon steel work.

Metal Transfer and the Weld Puddle

Across the arc, molten droplets detach from the core wire tip and travel into the puddle. In SMAW this transfer is usually a fine stream at proper settings, shifting to coarse, irregular globules when current is too low or the arc is too long. Those droplets land in a small pool of melted base metal mixed with filler, kept liquid for a few seconds before it freezes into the bead you see.

Polarity: The Setting That Changes Everything

Polarity decides where the heat goes. On DCEN (straight polarity), most heat sits at the electrode, giving faster melting and a shallower, calmer puddle. On DCEP (reverse polarity), more heat drives into the workpiece, producing deeper penetration and a firmer arc. AC alternates direction many times per second, splitting the difference and letting machines run a wide variety of rods. Because heat distribution differs, the same amperage can behave completely differently depending on connection.

Polarity	Heat concentration	Typical behavior	Common use
DCEN	Mostly at the electrode	Fast deposit, softer arc, lighter penetration	Thin material, some surfacing rods
DCEP	Mostly in the base metal	Deep, digging penetration, strong arc	E6010 root passes, E7018 structural work
AC	Balanced, alternating	Stable on most rods, less arc blow	Field repair, all-purpose machines

Classic example: E6010 is run on DCEP to achieve its characteristic deep, digging arc, which is exactly why pipeline root passes rely on it. Run that same rod on DCEN and it will stutter and refuse to burn properly. This is why electrode selection and polarity must be matched together — a principle covered in our all position welding rod guide and in Lincoln Electric’s AWS classification reference.

Electrodes Uncovered: AWS Classifications, Types, and Selection

Open a fresh box of stick electrodes and you will see a code stamped on the end of every rod: E7018, E6010, E6013. That short string is a complete specification, and once you can read it you can walk into any supply house and pick the right rod without asking for help. The code follows the American Welding Society’s A5.1 specification for carbon steel electrodes, and it packs four separate pieces of information into five or six characters. As Lincoln Electric’s AWS classification guide lays it out, each position in the code answers a specific question about strength, position, coating, and current.

Decoding the Number: E, 70, 1, 8

Take the most common structural rod in the world, the E7018, and split it apart:

Part	Meaning	Example
E	Electrode	Every stick rod starts with E
First two digits	Minimum tensile strength of the weld metal, in thousands of psi	E7018 = 70,000 psi; E6010 = 60,000 psi
Third digit	Approved welding positions	1 = all positions (flat, horizontal, vertical, overhead); 2 = flat and horizontal only
Fourth digit	Coating type and compatible current	E6010 = high cellulose sodium coating, DC; E7018 = low hydrogen potassium and iron powder coating, AC or DC

The tensile number matters more than beginners think. A 60,000 psi rod will not meet the strength callout on a joint designed around 70,000 psi filler, and swapping a 7018 for a 6013 “because it runs easier” is one of the quietest ways to build a weld that fails inspection.

The Six Rods You Will Actually Use

• E6010 — Deep, forceful penetration with a fast-freeze arc. It burns through mill scale, rust, and paint better than any other rod, and it is the classic root-pass electrode on pipe. DC only, all positions.
• E6011 — Essentially the AC version of the 6010. This is the rod that keeps old transformer “buzz box” welders useful on farms and in driveways. All positions, AC or DC.
• E6013 — Soft arc, smooth bead, low spatter, forgiving arc length. The friendliest rod for a first-timer and a good choice for thin sheet metal. AC or DC, all positions.
• E7014 — Iron powder in the coating lets it deposit metal faster with a lighter arc. Great for production fillet welds on plate in flat and horizontal positions.
• E7024 — High iron powder, high deposition, run with a drag technique on thick plate. Flat and horizontal only; it will not behave out of position.
• E7018 — Low hydrogen, quiet arc, excellent bead appearance, and the workhorse of structural steel. All positions on DC, and on AC if you buy the AC-rated version.

If you are curious about how these compare against specialty rods, our All Position Welding Rod Guide: Types, Uses & Tips covers the position rules in more depth, and Alloy Steel Welding Electrodes: Selection, Use & Safety explains what changes once you leave plain carbon steel behind.

Matching the Electrode to the Job

Base metal first. Match or exceed the base metal’s tensile strength. Most mild steel plate and pipe falls comfortably under 70,000 psi, which is why the 70-series covers the majority of work.

Joint design and position. A vertical-up pipe root often starts with a 6010 for penetration and finishes with a 7018 cap for toughness. Flat gusset work on a fabrication table can use a 7024 to save time. If the rod’s third digit does not allow the position you are in, no amount of technique will fix the sagging bead.

Power source. Check the fourth digit’s current requirement before you strike up. A DC-only 6010 will simply not run properly on an AC machine, and a DC inverter will run almost anything. The Miller Welds electrode guide is a useful cross-check when you are unsure which rod suits your machine.

Get in the habit of reading the code before you load the holder. Five characters tell you the strength you are depositing, the positions you may weld, the coating chemistry, and the current your machine must supply — everything you need to match the rod to the metal in front of you.

Equipment, Power Sources, and Proper Setup

Every stick welding decision starts with the machine. The power source decides which electrodes you can run, how long you can weld before it overheats, and whether you work in a shop bay or a ditch miles from the nearest outlet. Four categories of SMAW power source cover nearly every situation, along with the supporting hardware that keeps an arc stable.

Power source	Where it shines	Main trade-off
Transformer	Shop work, fixed stations, budget builds	Heavy, bulky, coarser adjustment
Inverter	Most SMAW work today, precision control	Higher upfront cost, more electronics to service
Engine driven	Field, rural, and pipeline work	Fuel, noise, exhaust, maintenance
Multi-process	Shops that also do MIG or TIG	Compromises on duty cycle or arc refinement

Transformer Machines: The Old Workhorses

Transformer machines convert line voltage to welding output through heavy copper or aluminum windings. They are simple, durable, and often cheap to repair, which is why some are still bolted to shop floors decades after purchase. The trade-off is weight: a mid-range transformer can weigh several times what an equivalent inverter weighs, and output adjustment is usually coarser. Most are AC-only, though rectifier-type transformers deliver DC for around-the-position work.

Inverter Power Sources

Inverter machines have become the default choice for SMAW, and for good reason. Rather than relying on a large 60 Hz transformer, an inverter rectifies incoming power, chops it at high frequency, and rebuilds the output electronically. The result is a much smaller footprint, increased efficiency, and noticeably improved arc control compared with many older transformer designs. Amperage adjustments come in fine increments, arc start characteristics can be tailored, and a 200-amp inverter may weigh less than a transformer machine half its output. For a welder who carries gear up ladders or works out of a truck, that difference matters.

Engine Driven and Multi-Process Machines

Engine driven welders pair a gasoline, diesel, or propane engine with a generator head, and they remain a staple for field work because they allow stick welding where no utility power exists. Many also provide auxiliary AC power for grinders, lights, and pumps. The costs are fuel, servicing, noise, and exhaust, so position the machine downwind and away from air intakes. Multi-process units bundle stick, MIG, and sometimes TIG into one chassis. They are convenient for a small shop, though you may give up some duty cycle or arc refinement. If your work occasionally branches into aluminum, the MIG side of those machines is well covered in Aluminum MIG Welding: The Complete Practical Guide.

Understanding Duty Cycle

Duty cycle is the percentage of a 10-minute period in which a welder can operate at a given amperage without exceeding its thermal limits. A machine rated 60% at 200 amps can weld for six minutes, then must idle for four. Push the amperage higher and the effective duty cycle drops, because heat builds faster in the windings and output electronics. Choosing a machine with more output than your typical rod requires is the simplest way to avoid thermal shutdown in the middle of a long pass.

Amperage Range, Leads, Clamps, and Holders

The machine’s usable amperage range has to overlap the electrodes you actually run. As a rough starting point, welders use about one amp per 0.001 inch of electrode diameter, but the manufacturer’s published range is the authority; Miller’s electrode overview lists typical settings for common rods. An Alloy Steel Welding Electrodes reference is useful when your base metal steps beyond plain carbon steel and the heat input window narrows.

Cables, clamps, and holders matter more than most beginners expect:

• Lead length and gauge: long or undersized cables cause voltage drop, so the arc softens and stalls. Use heavier gauge cable for runs beyond about 50 feet, and keep cables as short as the job allows.
• Work clamp: attach it to clean, bare metal close to the joint, never on painted, rusty, or loose parts. A poor ground is a leading cause of an erratic arc and arc blow.
• Electrode holder: use one rated for the amperage, with jaws that grip firmly and insulate properly. Replace cracked or pitted holders rather than taping them up.

For sourcing cables, clamps, regulators, and consumables, a supplier walkthrough like the Airgas Welding Equipment Guide covers what a complete setup includes.

Setting Up Safely in the Shop and the Field

A safe setup looks different in each environment, but the fundamentals are consistent with OSHA’s welding safety guidance.

• Shop: verify the outlet and breaker match the machine’s input requirements, coil and route leads clear of walkways, position a fire-resistant screen or curtains near bystanders, clear flammables within 35 feet, and keep an extinguisher within reach.
• Field: set the machine on level ground, uncoil welding leads fully (tightly coiled cable changes arc behavior), check ground clamps and connectors for heat before each job, and manage exhaust and fumes in any partially enclosed space.

Safety First: Fumes, Ventilation, PPE, and OSHA Compliance

Stick welding is one of the most accessible entry points into metalwork, but it is also one of the few trades where a beginner routinely faces extreme ultraviolet light, molten metal, and a chemical soup released from a burning electrode an arm’s length from their face. Most of that risk is manageable with ordinary discipline. The trouble starts when safety becomes a checklist you complete once instead of a habit you perform every time you strike an arc.

What Is Actually in Welding Fume

Welding fume is not a single substance. It is a fine aerosol of metal oxides, silicates, and fluorides produced when the arc breaks down the electrode coating and the base metal. Depending on the steel, the flux, and any coatings on the workpiece, a welder may inhale compounds of iron, manganese, nickel, chromium, and fluorides. According to OSHA’s welding safety fact sheet, fumes and gases generated by welding can cause short-term effects such as eye and respiratory irritation as well as long-term disease, which is why exposure control matters beyond the occasional weekend project.

Short-term overexposure shows up quickly. Metal fume fever, typically associated with zinc oxide released from galvanized steel, produces chills, fever, nausea, and a metallic taste that often appears hours after the work is done. It is a warning shot rather than a badge of toughness. If you are burning through galvanized pipe or painted structural members repeatedly, the answer is ventilation and respiratory protection, not tolerance.

Hexavalent Chromium and the 5 µg/m³ Limit

The exposure that draws the strictest regulation is hexavalent chromium, or Cr(VI), which forms when stainless steel and certain alloy steels are welded. OSHA’s Chromium (VI) standard (29 CFR 1910.1026, with the construction equivalent at 1926.1126) sets a Permissible Exposure Limit of 5 µg/m³ as an 8-hour time weighted average. Meeting that number in practice usually means a hierarchy of controls: substitution where possible, process changes, local exhaust ventilation, and only then respiratory protection. The practical takeaway for a shop welder is simple: if you weld stainless regularly, you need measured exposure data and a written control plan, not a guess. NIOSH maintains a useful reference of official PELs for welding-related substances worth reviewing before you write a procedure.

Electrode choice matters here too. Low-hydrogen consumables and basic coatings behave differently from cellulose or rutile coatings in terms of fume generation, which is one reason selection guides such as our Alloy Steel Welding Electrodes: Selection, Use & Safety treat consumable choice and exposure control as the same conversation.

Ventilation: Open Air, Shops, and Confined Spaces

Wind is not ventilation. Welding outdoors in a breeze may be perfectly acceptable for a short job, but the same arc inside a partially enclosed structure can push fume into your breathing zone and then hold it there. Per OSHA’s ventilation requirements under 29 CFR 1926.353, general ventilation must be sufficient to keep fumes and gases within safe limits, and where that cannot be assured, local exhaust or mechanical ventilation is required. 29 CFR 1910.252 carries the same principle into general industry.

PPE That Earns Its Keep

The minimum kit for stick welding is straightforward, and every piece has a specific job:

• Arc-rated helmet with the correct shade for your amperage, typically shade 10 to 13 for stick work, protecting against UV and IR as well as spatter.
• Fire-resistant jacket and leathers that cover the wrists and neck, because spatter falls where skin is exposed.
• Safety glasses with side shields worn under the helmet for grinding, chipping, and slag removal.
• Insulated gloves designed for welding, not general shop gloves.
• Respiratory protection selected for the specific contaminant, fitted properly, and used under a written program when engineering controls cannot guarantee clean air.
• Hearing protection in any shop where grinding, chipping, or engine-driven machines run alongside the arc.

Check the Metal Before You Strike the Arc

The most underestimated hazard is not the electrode; it is the surface underneath it. Paints, primers, coatings, galvanizing, and residual cleaning solvents can generate additional toxic exposures when burned, and coatings must be evaluated and normally removed before welding begins. Old structural steel is a classic example: unknowing welders have released dangerous decomposition products by burning through paint that contained lead. The same caution applies to cutting and gouging done alongside welding, as our guide to Air Arc Welding and Carbon Arc Gouging makes clear about the compressed-air-driven fume plume that gouging produces.

Treat safety as part of the skill, not a tax on it. A welder who controls fumes, checks the metal, wears the right protection, and knows when a space is off limits will still be welding in thirty years. That is the standard worth practicing from the first bead onward.

Welding Techniques, Positions, Joint Prep, and Beads

Technique is where stick and arc welding stops being a spec sheet and becomes a skill. Two welders can run the same machine, the same all-position welding rod, and the same amperage and still produce completely different welds. The gap is almost always arc control plus the discipline to do the boring prep before the arc ever strikes.

Striking the Arc and Holding It Steady

Two starts dominate. The scratch method works like striking a match: drag the electrode lightly across the plate until the arc catches, then lift. The tap method is exactly what it sounds like: touch the electrode to the joint and pull it back a hair. Beginners jam the rod into the plate and freeze it there. A controlled scratch or a light tap is far more reliable, especially on cold, mill-scaled steel.

Once the arc is lit, the single most important habit is arc length, the distance between the electrode tip and the puddle. Keep that gap roughly equal to the core wire diameter, so a 1/8-inch rod runs at about a 1/8-inch arc. Stretch it out and the arc wanders, gets noisy, pulls in air, and leaves porosity, spatter, and weak fusion. Squeeze it too tight and the electrode sticks or the flux coat drags through the puddle.

Three angles do the rest of the work:

• Work angle — how the rod tilts left or right relative to the joint, typically 90° for a fillet weld.
• Travel angle — the lean forward or backward in the direction of travel. A 5° to 15° drag angle suits most stick work.
• Electrode angle in position — for all-position electrodes such as E6010 and E6011, proper electrode angle is crucial for control, especially vertical and overhead. A few degrees of drift there can turn a clean root pass into a lump of frozen metal.

Judge travel speed by the puddle, not the arc. A wide, glassy puddle means you are too slow. A rod digging a trench with no molten pool behind it means you are too fast. Watch the leading edge of the puddle and hold it consistent.

The Four Welding Positions

AWS identifies four base positions, lettered G for groove welds and F for fillet welds:

Position	Groove / Fillet	What Makes It Hard
Flat	1G / 1F	Gravity helps; easiest, fastest deposition
Horizontal	2G / 2F	Gravity pulls the puddle down out of the joint
Vertical	3G / 3F	Molten metal wants to run downhill
Overhead	4G / 4F	Everything falls toward your hood

Vertical-up gives the deepest, strongest welds on thicker material because the puddle solidifies behind the arc and supports the metal above it. Vertical-down is faster and is the classic approach for E6010 root passes on pipe and thin sheet, but it demands a fast hand. Overhead work needs the shortest arc in the trade, small beads, and a narrow weave. The advantage of stick welding in all of these is simple: no shielding gas means no wind, no bottle, and no puddle blown out of shape on a ladder or under a truck.

Joint Types, Fit-Up, and Cleaning

Three joints come up constantly: the butt joint (two plates edge to edge), the lap joint (one plate overlapping another), and the T-joint (a fillet weld joining two pieces at a right angle). Each has its own prep expectations: square edges on thin material, V-bevels or J-bevels on heavy plate, a consistent root gap, and tack welds at each end to hold alignment through shrinkage.

Mill scale, the flaky blue-black oxide on hot-rolled steel, looks harmless but acts as an insulator that can block fusion and crack as it heats. Oil and moisture are worse, breaking down into hydrogen and gas right inside the puddle. Switch metals and the rules tighten further, which is why cleaning aluminum before welding takes more care than wiping down mild steel.

Stringer Beads, Weaving, and Multi-Pass Work

A stringer bead is a straight, drag-only pass with no side-to-side motion. It deposits the cleanest, most consistent metal and is what codes and inspectors expect on critical work. A weave moves the electrode side to side to cover a wider joint in fewer passes. It is useful, but excessive weaving creates a wider, hotter weld with more slag and a higher chance of inclusions. Most procedures cap the weave at roughly two to three electrode diameters wide.

Whenever a joint needs more than one pass, clean the previous bead completely, chipping the slag and wire brushing for trapped glass, before laying the next one. Watch interpass temperature, stagger your passes to spread heat, and skip-weld long joints to keep distortion from bowing the workpiece. On low-alloy and specialty steels, filler selection matters as much as technique, so review alloy steel welding electrode guidance before you commit to a rod. And remember that the third digit in an AWS classification, such as the “1” in E6011 or E7018, is what tells you the rod is rated for all positions.

None of this is complicated. It is simply sequential: clean, fit, tack, set your angles, strike the arc, watch the puddle, clean between passes. Skip a step and the weld tells on you.

Benefits, Limitations, and How Stick Welding Compares to MIG and TIG

Ask ten welders which process is “best” and you will get ten different answers, usually delivered with complete confidence. The more useful question is which process fits the job in front of you. Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW/MIG), and Gas Tungsten Arc Welding (GTAW/TIG) are all arc welding processes, but they behave very differently once the arc is lit. Here is an honest, side-by-side look at where stick welding wins, where it struggles, and how to choose.

Where Stick Welding Thrives

The single biggest practical advantage of SMAW is that it does not rely on an external cylinder of shielding gas. The flux coating on the electrode generates its own protective atmosphere as it burns, so a gust of wind that would blow a MIG shield off the puddle does very little to a stick arc. That makes stick welding the default choice for open fields, rooftops, trenches, and windy docksides where gas-shielded work becomes unreliable or impossible.

Other strengths stack up quickly:

• Rough base metal. SMAW is the go-to process for repairs on older, weathered, rusty, or otherwise less-than-ideal steel. It welds a wide variety of carbon steels and tolerates surface contamination that would wreck a TIG weld.
• Portability. A compact power source, a stinger, a ground clamp, and a carton of rods are all you need. Engine-driven units run the same electrodes with no shop power at all.
• Position and joint flexibility. Several electrode families are true all-position consumables, a point covered in our All Position Welding Rod Guide: Types, Uses & Tips.
• Cost of entry. Stick machines remain the least expensive way to start arc welding, and there is no wire feeder, gas regulator, or liner to maintain.
• Deep penetration. Clean, sound root passes on plate and pipe are a SMAW specialty, especially with cellulosic electrodes.

For a fuller breakdown of these strengths, see Advantages of Stick Welding: Why SMAW Still Wins.

Where Stick Welding Falls Short

The trade-offs are real. Every SMAW bead is covered in slag that must be chipped and wire-brushed between passes on a multi-pass weld, adding post-weld cleanup time that a solid-wire MIG bead simply does not demand. Stick also leaves more spatter, requires you to stop and swap consumed electrodes, and wastes a stub end each time. On long production runs, continuous wire processes usually deposit metal faster with less interruption. Low-hydrogen electrodes such as E7018 also have AWS A5.1 storage requirements, meaning damp rods must be re-baked or discarded. Finally, arc length and travel speed are controlled entirely by hand, so the learning curve is steeper than MIG.

SMAW vs GMAW (MIG)

MIG is faster to learn, cleaner after the weld, and highly efficient on thin-to-medium sheet in a shop. Its weakness is exactly where stick is strongest: the shielding gas can be disrupted by wind, the gun, liner, and contact tip need routine attention, and the base metal must be considerably cleaner. That last point matters most with aluminum, where surface prep decides the weld quality; the Aluminum Cleaner for Welding: How to Prep Aluminum Right guide explains why, and Aluminum MIG Welding: The Complete Practical Guide covers the process itself. If you need MIG outdoors, gasless flux-cored wire offers a middle ground, though it produces its own slag and spatter just like stick.

SMAW vs GTAW (TIG)

TIG produces the cleanest, most attractive, most precisely controlled weld of the three and handles thin material, stainless, and non-ferrous metals beautifully. In exchange it is slow, expensive to set up, intolerant of dirt or oil, and equally dependent on an uncontaminated shielding gas envelope. TIG is the wrong tool for a muddy pipeline tie-in; SMAW is the wrong tool for a visible, cosmetically critical handrail on polished stainless. Match the process to the work.

Factor	SMAW (Stick)	GMAW (MIG)	GTAW (TIG)
Shielding	Flux coating, no cylinder	External gas cylinder	External gas cylinder
Outdoor/wind performance	Excellent	Poor unless flux-cored	Poor
Dirty or rusty steel	Good	Fair	Poor
Post-weld cleanup	Slag chipping and brushing	Minimal	Minimal
Learning curve	Steeper	Gentlest	Steepest
Travel speed	Moderate	Fastest	Slowest
Equipment cost	Lowest	Moderate	Highest
Best fit	Field repair, pipe, structural	Production, sheet, fabrication	Precision, thin, exotic metals

Most experienced welders eventually own a multi-process machine and switch based on conditions rather than loyalty. Understanding all three does not make you indecisive; it makes you the person who gets the weld right the first time, in weather that does not cooperate.

Common Mistakes, Troubleshooting, and Proven Solutions

Even the most seasoned welder will run into defects while performing stick and arc welding. The Shielded Metal Arc Welding (SMAW) process is incredibly forgiving in harsh environments, but small errors in technique, setup, or electrode care can lead to weak or failed welds. With the right knowledge, the majority of these issues can be corrected in seconds, saving both time and material.

Sticking Electrodes

Few things are as frustrating as an electrode that fuses to the base metal. This is one of the most common issues for beginners. It is often caused by an arc that is too short, amperage that is set too low, or poor contact with the work clamp.

• Likely Cause: Low heat input preventing proper arc initiation.
• Actionable Solution: Strike the arc with a quick scratching motion, increase amperage slightly, and maintain a proper arc length. Ensure your work clamp is free of rust or paint for a solid connection.

Porosity

Porosity appears as small gas pockets trapped within the weld bead. These pockets drastically weaken the joint. Contaminants such as oil, grease, paint, or moisture are the primary culprits, especially when working with specific filler metals. Choosing the right rod, such as those covered in our All Position Welding Rod Guide, can help combat this issue in certain positions.

• Likely Cause: Dirty base metal, damp electrodes, or shielding interference from wind.
• Actionable Solution: Thoroughly clean the joint, use dry electrodes, and shield the work area from heavy drafts. For high alloy work, be sure to select compatible rods found in our Alloy Steel Welding Electrodes: Selection, Use & Safety guide.

Slag Inclusions

Slag is a byproduct of the flux, however, if it becomes trapped between passes or in the bead, it creates a weak plane. This defect is commonly seen in multi-pass welds or when travel speed is rushed.

• Likely Cause: Improper bead placement, lack of chipping, or weaving too wide.
• Actionable Solution: Remove all slag between passes with a chipping hammer and wire brush. Utilize stringer beads for tight joints and allow for proper fusion between each pass.

Undercut

Undercut is a groove melted into the base metal that is left unfilled by weld metal. As noted by the Miller Electric Knowledge Hub, undercut is often caused by excessive amperage, too long of an arc length, or an improper travel speed and electrode angle. This can greatly reduce the cross-sectional strength of the joint.

• Likely Cause: High heat input paired with poor torch manipulation.
• Actionable Solution: Reduce amperage to the recommended range for your electrode, shorten your arc, and adjust to a travel speed that allows the puddle to fill the toes of the joint.

Lack of Fusion, Cracking, and Damp Electrodes

Lack of fusion occurs when the weld metal fails to bond with the base metal or previous passes. This is often paired with improper joint prep or too fast of travel. Cracking, on the other hand, can be delayed and catastrophic. One of the leading preventative measures lies within electrode storage. Low hydrogen electrodes, such as E7018, are hygroscopic and can absorb moisture from the air. If exposed for extended periods, they may require proper storage or baking per the manufacturer’s requirements to prevent hydrogen induced cracking. These precautions are echoed in AWS electrode classification guidelines.

Arc Blow

Arc blow is the deflection of the arc away from its intended path, causing uneven beads. More common with DC on certain joints, it can be extremely frustrating. Arc blow can be mitigated by changing work lead placement, shortening lead lengths, or switching to AC where applicable. For larger structural jobs, keeping lead runs tidy is not a luxury, but a necessity for quality work.

Most SMAW defects do not stem from a lack of talent, but from a lack of troubleshooting. By correcting these common mistakes, you will not only strengthen your welds, but also build the consistency that separates a hobbyist from a true tradesman. Take the time to diagnose, adjust, and test with scrap metal before moving onto your final work. Your skill will grow far faster because of it.

Practical Applications, Tips From the Trade, and Workforce Demand

Classroom theory explains how an arc behaves, but stick and arc welding earned their reputation in places where the wind is blowing, the steel is dirty, and the nearest gas supplier is an hour away. Very few processes show up in as many industries as Shielded Metal Arc Welding, and knowing where it fits matters as much as knowing how to strike an arc.

Where Stick Welding Earns Its Keep

Pipelines and pipe work. Field joints on gathering and transmission pipelines frequently start with a stick root and hot pass, because the root needs deep, reliable penetration without a gas bottle tipping over in a trench. Fill and cap passes are then tied in with other processes. Plant piping follows the same pattern, where a stick welder is often the only tool that can reach an out-of-position joint inside a rack.

Structural steel and infrastructure. Bridges, stadium frames, industrial buildings, and crane rails depend on all-position capability and low-hydrogen electrodes such as E7018. Ironworkers and shop fabricators use SMAW for field fit-up work where mill tolerance is a dream and real-world gaps are the norm. Public infrastructure projects, from water mains to culverts and road structures, lean on stick welding because the equipment is simple to transport and repair on site.

Farms, ranches, and remote repair. This is where SMAW has almost no competition. A small engine-driven machine can weld a snapped hitch, a loader bucket, or a gate hinge with nothing but a battery, a ground clamp, and a box of rods. The flux coating tolerates light rust and mill scale far better than wire processes, and the advantages of stick welding in field conditions become obvious the first time you work a mile from the nearest outlet.

Maintenance, shipbuilding, and heavy repair. Maintenance crews keep stick machines running because one power source handles everything from bracket repairs to worn shaft build-up. Shipyards and marine yards use SMAW for hull work, deck structures, and repairs in cramped, poorly ventilated compartments where a versatile electrode family matters more than deposition speed. Pressure vessel and boiler shops are another strong hold; specialists such as Alamo Welding & Boiler Works show how SMAW remains central to high-consequence fabrication and repair.

Application	Why SMAW fits	Common electrodes
Pipeline field joints	Portable, wind-tolerant, deep root penetration	E6010, E6011 root; E7018 fill and cap
Structural steel and bridges	All-position, low hydrogen for critical joints	E7018, E7014
Farm and rural repair	No shielding gas, tolerates rust and scale	E6011, E6013
Maintenance and millwright work	One machine, many jobs, easy field setup	E6013, E7014, E7024
Shipbuilding and marine repair	Reaches confined and out-of-position joints	E7018, all-position rods

Tips From the Trade

• Match the rod to the steel, not the habit. A quick rundown of all-position welding rod types and uses will save you from fighting a flat-only rod overhead.
• Keep low-hydrogen rods dry. Open one pack at a time, store the rest in a heated rod quiver or rod oven, and follow the manufacturer’s reconditioning guidance. Damp E7018 is one of the most common sources of porosity and hydrogen cracking.
• Mark your machine. Put a strip of tape next to the amperage dial and note the setting that worked for each rod diameter, and you will recreate good results in minutes instead of guessing every session.
• Clean between passes. Chip the slag thoroughly and run a wire wheel before the next bead. Slag trapped under a fresh pass is a defect you will explain to an inspector later.
• Prepare to rework. Bad joints often need to be gouged out first, and air arc welding and carbon arc gouging is the standard way to remove defective metal before rewelding.
• Run stringers on critical work. Narrow stringer beads control heat input better than wide weaves, especially on root passes and low-alloy steel.
• Place your ground strategically. Short leads and a clean clamp near the joint reduce arc blow, which is especially annoying on AC and unbalanced DC runs.

Workforce Demand: Why Learning the Craft Still Pays

The career side of this trade is unusually well documented. According to American Welding Society workforce reporting, the United States is projected to need roughly 320,500 new welding professionals by 2029, with about 80,000 openings each year between 2025 and 2029 created by both industry growth and workers leaving the field. The same data estimates the existing U.S. welding workforce at around 771,000 people, with more than 157,000 approaching retirement age. Current figures are tracked at weldingworkforcedata.com.

What that means practically: the industries driving those openings, including pipelines, structural steel, maintenance, shipbuilding, and infrastructure, are exactly the industries still running SMAW every day. A welder who can strike a consistent arc, read a drawing, and produce a code-quality stick weld has a portable skill that does not disappear when a company upgrades its machines. For people starting out, a structured aluminium welding course and career overview illustrates how training programs typically combine classroom theory, supervised practice, and qualification testing.

Add honest self-assessment: film your beads, compare them to acceptable profiles, and fix one variable at a time. Consistent practice, clean preparation, and respect for safety and code requirements are what turn a passing hobbyist into the welder a supervisor trusts with the joint nobody else wants.

Conclusion: Mastering Stick and Arc Welding For Years to Come

Think back to the storm-damaged farm gate from the opening of this guide. The welder who fixed that hinge did not win with a premium machine. They won because they could strike an arc in wind, burn a 6011 root on dirty steel, read the puddle, and keep the smoke out of their lungs. That is stick and arc welding in one sentence: fundamentals beat equipment, and preparation beats luck.

We have walked the full arc of knowledge here, from what SMAW actually is to how it compares with MIG and TIG. If you take nothing else from these ten sections, take these lessons to the bench.

The Core Lessons Worth Keeping

• The process itself. Shielded Metal Arc Welding uses a flux-coated consumable electrode to create the arc, melt the base metal, and generate its own shielding gas and slag blanket at once. That self-shielding design is exactly why stick welding keeps winning outdoors and in remote repair work.
• Electrode selection is half the job. The AWS classification code tells you tensile strength, position capability, flux type, and current. A fast-freeze 6010 or 6011 root under a 7018 cap is still one of the most reliable combinations in the industry, and it pays to study which rod belongs in which position and which joint.
• Setup matters more than spend. Clean metal, correct polarity, proper amperage for the rod diameter, tight leads, and dry electrodes will outperform an expensive machine fighting dirty plate and a loose ground clamp every single time.
• Technique is a set of habits, not a talent. Consistent arc length, steady travel speed, correct work and travel angles, and disciplined stringer beads carry you through flat, horizontal, vertical, and overhead work.
• Safety is a skill, not a chore. Ventilation awareness, proper PPE, and familiarity with standards such as OSHA’s ventilation and fume control requirements for welding are as much a part of craft competence as a clean bead profile.

Your Realistic Action Plan

Mastery does not come from reading another article; it comes from repetition. Here is a practical path forward that does not require quitting your job tomorrow.

1. Buy three boxes of rod, not ten. Start with 3/32 in. or 1/8 in. E6013 for general practice, E6011 for dirty metal and root passes, and E7018 for anything needing real strength. Handle low-hydrogen rod properly from day one: rods stay in the oven or a sealed container.
2. Build a coupon routine. Cut flat plate into manageable pieces, run a bead, let it cool, chip the slag, wire brush it, and study it honestly. Was the bead uniform? Was there undercut? Any slag inclusions on a multi-pass weld? Our troubleshooting and gouging guide is useful when a bad weld has to come back out.
3. Work out of position on purpose. Most beginners live in flat work. Schedule overhead and vertical-up sessions even when they turn out ugly. Position skill is what separates a hobbyist from a hireable welder.
4. Treat ventilation as part of the machine. Weld outdoors or in front of proper exhaust whenever you can, keep your head out of the plume, and never enter a confined space without a written plan and monitoring. Review OSHA’s general industry welding and cutting standard once a year.
5. Read and work toward a code. If structural or pressure work is your goal, start reading AWS D1.1 or the applicable ASME reference before an employer asks you to. Code literacy is what turns a welder into a technician.
6. Find work, find a mentor, find a shop. The demand side of this trade is real: industry coverage such as AWS Welding Digest’s reporting on the welder shortage and ongoing welding workforce data show consistent openings across construction, energy, and manufacturing. A patient mentor in that environment will teach you more in six months than solo practice teaches in two years.

A Process That Is Not Going Anywhere

Every few years someone declares stick welding obsolete. Then a pipeline crew roots a pass in a muddy ditch, a farm welder repairs a loader bucket an hour from town, or a shipyard welder works in a ventilated shaft where no gas bottle could safely be staged. Stick and arc welding is not a dying craft. It remains as relevant as it was a century ago because it is portable, tolerant of contaminated metal, and effective where other processes simply cannot go.

The path from your first stuck electrode to a confident, code-competent welder is long, but it is walked one bead at a time. Set your amperage, strike your arc, keep it short and steady, watch the puddle, and keep showing up. The skill compounds, and the trade will meet you halfway.

Frequently Asked Questions

What is the difference between arc welding and stick welding?

Arc welding is the broad category of welding that uses an electric arc as the heat source. Stick welding is the most common name for Shielded Metal Arc Welding (SMAW), which specifically uses a flux coated consumable stick electrode.

What electrodes should a beginner learn first?

Most beginners start with E6013 for clean, new sheet metal due to its easy arc, or E6011 for more forgiving work on older steel. E7018 is an extremely valuable electrode to learn, however its low hydrogen properties require extra care with storage.

Can you stick weld outside in the wind?

Yes, this is one of SMAW’s greatest advantages. Unlike gas shielded processes, the flux coating produces its own shielding gas and slag, however heavy wind can still blow it away and may require a windbreak to produce quality, clean welds.

Is stick welding dangerous to your lungs?

It can be if proper precautions aren’t taken. Welding fumes contain metal oxides and, depending on the base metal and rods, can contain hazardous elements. Adequate ventilation, positioning yourself upwind, following OSHA guidance, and utilizing respiratory protection when needed are all essential.

Do I need gas for stick welding?

No. Stick welding is self shielding. The flux coating on the electrode decomposes when heated, creating a shielding gas and a layer of slag to protect the molten weld puddle from the atmosphere.

What polarity should I use for E6010 and E7018?

E6010 is most commonly ran on DCEP (Direct Current Electrode Positive) for maximum penetration. E7018 can be ran on DCEP or AC depending on the rod and machine, with DCEP often being preferred for a smooth, stable arc.

Why is my stick electrode sticking to the metal?

This is usually caused by insufficient amperage for the electrode size, too short of an arc, or poor technique. Try increasing amperage slightly, strike like striking a match, and maintain a consistent arc length to prevent sticking.

Do I have to chip the slag off of every pass?

Yes for most multi-pass welds. Slag inclusions can be created if slag is trapped between passes. Thoroughly chip and brush with a chipping hammer and wire brush between passes to ensure proper fusion on the following bead.

Is there still a demand for stick welders?

Absolutely. With hundreds of thousands of welders nearing retirement and over 320,500 new welding professionals projected to be needed by 2029 according to AWS workforce data, skilled stick welders remain in high demand for repair, structural, and field work.

What is the biggest difference between E6010 and E6011?

Both are deep penetrating, all-position rods. The biggest difference is current compatibility. E6010 is primarily ran on DCEP, while E6011 is designed to run on both AC and DCEP, making it much more versatile for older or generator powered machines.
