Is Arc Welding the Same as Stick Welding? A Complete Breakdown

You’re at a job site and two welders argue over the terminology of their process. One says they’re doing arc welding, the other says stick welding. Are they both correct, or are they talking about two entirely different things?

Introduction: Clearing Up The Confusion

Here is a scene that plays out in fabrication shops, on pipeline crews, and in nearly every welding classroom. Two welders work the same joint. One says, “I’m stick welding this.” The other says, “I’m doing arc welding.” A third welder says nothing, quietly switches his machine from flux core back to stick because the wind picked up, and goes back to work. Everybody walks away convinced they were having the same conversation. They were not.

This is not a technical disagreement. It is a language problem, and language problems in this trade cause real consequences: misread drawings, mislabeled inspection reports, incorrect training hours on a welder’s qualification ticket, and the wrong process chosen for a joint that needed something else.

The short answer, unpacked in detail below: no, arc welding and stick welding are not the same thing. “Arc welding” is a category, a family of processes. “Stick welding” is the everyday trade name for one member of that family, Shielded Metal Arc Welding, or SMAW. Every stick weld is an arc weld. Not every arc weld is a stick weld. When a welder says “I arc welded that frame,” you still do not know what machine he ran, what the filler metal was, whether the joint was gas shielded, or how the inspection paperwork gets filed.

Why the Two Words Keep Getting Tangled Up

Part of the trouble is that “arc welding” describes the most fundamental idea in the trade. An electric arc forms between an electrode and the workpiece, the arc melts the base metal, and the molten pool cools into a weld. Nearly every modern joining process is built on that single principle, so “arc welding” became shorthand for the whole discipline in a way a specialist would never use it.

Meanwhile, SMAW is genuinely the process most people picture when they hear “welding.” The electrode is a thick rod with a coating of flux on it, the welder grips it in a holder, and the flux burns away into a slag that somebody chips off with a hammer. It is the most recognizable image in the trade, so the trade adopted “stick” as its nickname. You can read more about why SMAW still wins in so many real world situations further along in this piece.

Here is the terminology map most readers need:

Term you will hear	What it actually is	Level of specificity
Arc welding	Any process that creates a weld using an electric arc	Broad category
Stick welding / SMAW	Flux coated electrode, electrode acts as filler metal, slag forms on top	One specific process
MIG / GMAW	Continuous wire feed, shielding gas, no slag	One specific process
TIG / GTAW	Non consumable tungsten electrode, shielding gas, no slag	One specific process
FCAW	Flux cored wire, often self shielded, electrode is consumable	One specific process
Air arc gouging	Carbon arc used to remove metal, not a joining process	Related but separate

That last row matters too, because air arc gouging uses an arc but removes metal rather than joining it, and it is not SMAW under any circumstances. Welders who mix up welding and gouging terminology tend to mix up other categories as well.

Why Getting the Terminology Right Actually Matters

Sloppy language has consequences. Procedure specifications, contract drawings, and inspection documents all reference process designations, and the recognized reference point for those designations is the American Welding Society, whose standards and welding procedure specifications are what most codes and quality programs are built on. When a drawing says “weld to AWS D1.1 with an approved process,” the word “approved” is doing a lot of work, and knowing the difference between a category and a specific process is the start of it.

Safety documentation works the same way. OSHA hot work and welding fume rules apply to electric arc welding as a family, including fume exposure that welders routinely underestimate. NIOSH research on welding fume exposure and metal fume fever is why local exhaust ventilation and proper respirator selection matter regardless of which process you are running. If you cannot name the process, you cannot pick the right controls.

What This Article Will Cover

This article answers one principal question and a handful of supporting ones:

• Is arc welding the same as stick welding? (Direct answer, with the reasoning behind it.)
• What is actually happening inside an electric arc, and why does the arc have to be shielded?
• What makes SMAW different from the other processes in the family, equipment and electrode handling included?
• Which other processes fall under the arc welding umbrella, and what are they good for?
• Where does SMAW outperform the alternatives, and where does it fight you?

We will stay focused on the terminology and the practical reality behind it. No product rankings, no shopping lists. Once you finish, you will be able to correct the next welder who says “arc welding” when they mean stick and all position rod, and you will know exactly why the distinction was worth making.

The Science Behind The Arc: How Arc Welding Works

Strip away the acronyms and every process in this article runs on the same physical trick: sustain an electric arc and aim it at metal. That single idea explains why stick welding behaves the way it does, why MIG spits, and why TIG on aluminum insists on a stubborn gas blanket. It is also what settles the naming debate: “arc” describes the physical event, while process names describe how that event gets packaged.

What The Arc Actually Is

An electric arc is not a flame. It is a plasma, a column of ionized gas created when an electrical potential difference forces electrons across a gap between two conductors. The instant that gap ionizes, the gas turns conductive, current flows, and a stable arc forms with a core temperature that can exceed 6,000 °F. That is more than enough to melt steel, aluminum, or stainless steel outright.

Two electrodes sit at either end of the gap. The negative one is the cathode; the positive one is the anode. With direct current electrode negative (DCEN), common on TIG and many stick applications, the workpiece becomes the anode and picks up roughly two-thirds of the arc’s heat. Reverse it to direct current electrode positive (DCEP) and heat concentrates on the electrode instead. That trade is exactly why thin-material TIG often runs DCEP: the extra heat at the electrode is what breaks up the refractory aluminum oxide layer. The American Welding Society treats polarity as a controlled variable in nearly every welding procedure specification, because flipping it changes penetration, electrode consumption, and bead shape.

Heat Input And The Weld Pool

The molten puddle you push along the joint is the weld pool, and it forms because the arc delivers heat to the surface faster than the metal can conduct it away. How much heat goes in per unit length of travel is the number welders actually live by:

Heat input (kJ/mm) = (Volts × Amps × 60) ÷ (travel speed in mm/min × 1000)

Turn that crank up and you get deeper penetration, a wider bead, and a bigger, lazier pool. Turn it down and the arc skitters over cold metal, which is precisely how you get lack of fusion, undercut, and cold laps. The other lever is arc length. Hold the electrode close, roughly one electrode diameter away, and voltage stays low, penetration stays deep, and the atmosphere never gets a chance to reach the pool. Drag that arc out and voltage climbs, the bead flattens and widens, spatter flies, and shielding becomes harder to maintain. Guidance from AWS publications such as D1.1, and the procedure specifications built on them, is consistent on this point: short arc, controlled travel speed, specified voltage.

The pool has its own physics. Surface tension pulls the hot, contaminated top layer toward the cooler edges, while the arc’s plasma jet and electromagnetic forces push molten metal backward into a cavity behind the arc. That cavity, about the width of the arc, is where fusion happens.

Why Shielding Is Non-Negotiable

Every one of these processes ships with a shielding system for good reason. The air around you is roughly 78 percent nitrogen and 21 percent oxygen, and it carries moisture. Nitrogen dissolves into hot molten metal and can float out as porosity or leave the weld brittle. Oxygen oxidizes the puddle and forms gas pockets. Moisture brings hydrogen, the classic culprit in heat-affected-zone cracking of higher-strength steels. A sound weld needs a clean, protected molten pool, and that requirement is one of the few things all arc welding processes share without exception.

Process	How the weld area is shielded	What the welder deals with
SMAW (stick)	Flux coating decomposes into a protective gas envelope	A slag cap that must be chipped or ground off
GMAW (MIG)	Shielding gas pushed from the gun: argon, CO2, or a blend	Spatter, and heavier fume from coated wire
GTAW (TIG)	Argon or helium delivered through the torch cup	Clean bead, very little spatter
FCAW	Flux inside the tubular wire, much like stick	Slag or a light spray, depending on wire type
SAW	Granular flux laid over the joint ahead of the arc	Molten slag sitting on top of the finished bead

Not every arc-related process shields, though. Air carbon arc gouging runs a bare electrode in open air on purpose, because the goal is to blow metal away rather than make a clean weld. And no amount of shielding helps if the surface is wrong; on aluminum the oxide skin has to come off before the arc can bond properly, which our guide to aluminum MIG welding covers in practical detail.

What Is Stick Welding (SMAW)? Definition And Process

On a job site, a welder holds a short rod in a spring-loaded clamp and runs an arc across the joint. That rod is the heart of Shielded Metal Arc Welding, the process the American Welding Society designates as SMAW, listed as process number 1 in AWS literature. Everyone calls it stick welding because the consumable looks exactly like a stick.

Unlike MIG or TIG, where filler metal arrives as wire fed through a gun, SMAW uses a consumable, flux-coated electrode roughly 12 inches long and 1/16 to 5/32 inch thick. It sits in an electrode holder between copper jaws and is consumed as the arc melts it. The coating is what makes the process possible, creating both the shielding atmosphere and the slag that let molten metal cool cleanly.

The Equipment You Need

SMAW is famous for simplicity: a power source, an electrode holder, a work lead with a ground clamp, the electrode, and proper personal protection.

Modern machines usually run direct current, either constant current (CC), constant voltage (CV), or constant current with constant voltage. Constant current is the classic stick setup, keeping the arc steady as the electrode melts back; constant voltage makes it easier to hold a given arc length.

For amperage, a long-standing rule of thumb for mild steel is roughly one amp for every 0.001 inch of electrode diameter. That puts a 3/32-inch electrode near 60 to 80 amps and a 1/8-inch electrode around 110 to 130 amps. Check the electrode packaging, since the maker’s recommended ranges take priority. Our welding equipment guide covers selection in more detail.

Safety gear matters more here than in almost any other process. The arc gives off intense visible light and infrared heat, and the fumes, especially from coated electrodes, need local exhaust ventilation and respiratory protection. OSHA sets the legal requirements for ventilation, protective clothing, and electrode handling, while ANSI Z49.1 provides the detailed safety practices most shops follow.

The Electrode and Its Flux Coating

The flux coating is a carefully engineered mixture. Depending on classification, it may contain rutile, cellulose, iron powder, lime, silica, fluorides, and small amounts of alloying elements. Some control the arc, some influence penetration, some add strength, and some help slag peel off cleanly.

As the electrode melts, the coating burns and decomposes into the two things that matter most in the process:

• A gaseous shield around the arc and the molten weld pool, keeping oxygen and nitrogen out of the hot metal.
• Molten slag that floats on the pool, protects it while it cools, then hardens into a brittle crust you knock off with a chipping hammer or wire brush between passes.

That is why SMAW works in a windy field or on a rusted pipe and still produces a sound weld: the metal does not lean on a clean atmosphere or surface the way a gas-shielded process does. The trade-off is that slag must be removed every time, and leaving chunks in the bead traps defects.

Electrode classifications follow AWS A5.1, and the “E” simply means electrode.

Classification	Common Use
E6013	General purpose, all-position mild steel, easy slag
E6010	Deep penetration cellulosic; root passes and pipe
E7018	Low-hydrogen for structural and pressure work, keep dry
E7028	High iron powder, fast deposition on fill and cap

Our all-position rod guide walks through choosing by position, and the alloy steel electrode guide covers low-alloy and high-strength selections.

The Process, Step by Step

1. Prepare. Clean the joint, remove sharp edges that cause cracking, and attach the ground clamp to the workpiece.
2. Set the machine. Match amperage to electrode diameter and position, and confirm polarity.
3. Strike the arc. Scratch-start, then lift slightly into the joint. Tapping repeatedly is the classic beginner mistake.
4. Hold a short arc. About 1/16 to 1/8 inch, roughly electrode diameter. Short arcs concentrate heat, improve penetration, cut spatter, and control the puddle.
5. Travel and build the bead. Keep a consistent angle and speed, weave if the bead is wide, and let each pass cool and clean.
6. Chip the slag. Remove it fully, then restart in the weld toe so the new bead ties in smoothly.
7. Inspect and dress. Grind out defects, undercut, or stray spatter before signing off.

For structural and regulated work, ASME Section IX governs welder and procedure qualification, and you qualify by process and position. AWS D1.1 does similar work for structural steel. A drawing that lists “arc welding” may mean SMAW specifically or any qualified process, which is why the distinction matters on a job site.

Why Everyone Says “Stick Welding”

The nickname comes from the consumable: a stick electrode is a physical rod, about the length of a carpenter’s pencil but thicker, and it was sold by the pound and the box for decades. Easy to say on a noisy job site, hard to forget.

But do not confuse it with air arc welding, which is a cutting process. There, “arc” refers to carbon arc gouging, where a carbon electrode and compressed air blow molten metal away, closer to a cutting torch than to any arc welding process. For why the process still earns its place on modern jobs, see our piece on the advantages of stick welding.

Is Arc Welding The Same As Stick Welding? The Direct Answer

Short answer: no. Stick welding is always arc welding, but arc welding is never automatically stick welding. One names a specific process. The other names a whole family of processes.

Saying “I do arc welding” describes a family of processes. Saying “I do stick welding” names the exact one: Shielded Metal Arc Welding, or SMAW. So all stick welding is arc welding, but not all arc welding is stick welding.

What “Arc Welding” Actually Means

Every fusion welding process in common use melts base metal with heat. The arc processes are set apart by their heat source: an electric arc struck between an electrode and the workpiece. No arc, no arc welding, which is why the term stretches so wide.

The American Welding Society groups these processes by how the arc is created and how the weld zone is protected. The family includes shielded metal arc, gas metal arc, gas tungsten arc, flux cored arc, submerged arc, and air carbon arc. They range from semiautomatic to fully automated and differ sharply in filler delivery, shielding, positions, and bead profile.

What “Stick Welding” Actually Means

“Stick” is the trade nickname for SMAW. The consumable is a solid filler rod coated in thick flux. As the arc burns, the coating melts and decomposes, releasing shielding gas over the molten pool and floating a layer of slag you chip off once the weld cools. It looks like a stick because it sits in an electrode holder.

The nickname spread because of practicality. Stick needs no shielding cylinder, no wire feeder, and no gas lines, so it is the process you grab on a ladder, out on a pipeline, or fixing a gate hinge in the rain. Why SMAW still wins in so many shops digs into that side.

Side By Side Comparison

Point of comparison	“Arc welding” as a category	Stick welding (SMAW)
What it describes	One heat source, many processes	One named process
Processes included	SMAW, GMAW, GTAW, FCAW, SAW, more	One
Electrode and filler	Varies by process	Flux-coated consumable
Shielding	Depends on the process	Made by the flux coating

Where The Confusion Comes From

Common usage collapses everything into “arc welding” because most shop work outside the gas processes really is stick work, and people say “arc” the way they say “welding” generically. In some regions and on older job sites, “arc” became an informal synonym for SMAW, the way people say “soldering” for brazing.

There is also the look of it. Most arc processes throw a bright flash and show a rod in a holder, so laypeople assume one process, hiding what matters: deposition rate, spatter, and post-weld cleanup. The words also land in job ads, course descriptions, and technical documents, where a resume reading “arc welding” tells a hiring manager almost nothing.

When Each Term Is Correct

Use “stick welding” or “SMAW” when you mean the specific process, such as a welder listing qualifications or a shop discussing a procedure. For gear, the all-position electrode guide only makes sense in an SMAW context, since flux-cored wire and solid MIG wire are handled differently.

Use “arc welding” when you mean the family, such as a training overview, a shop capability statement, or a general discussion of arc processes. It is fine as casual shop talk too, as long as nobody reads it as a specification.

Use “stick” on the floor and “SMAW” in a resume, WPS, contract, inspection report, or anything that has to survive a code check. ASME and ANSI standards, along with AWS codes, reference processes by numbered classification and name, never by nickname. When a document must be unambiguous, write both: “SMAW (stick welding), AWS D1.1, electrode E7018.”

Why Getting It Right Matters

Process selection drives qualification, filler metal choice, procedure development, inspection hold points, and cleanup time. Calling an FCAW job “stick welding” in a paperwork chain can mean the wrong filler gets approved, the wrong procedure gets written, and the joint misses the code. Codes published by AWS and shop safety expectations referenced by OSHA treat each process as a separate qualified activity for a reason.

The safety layer differs too: stick welding’s biggest exposure is fume, spatter, and UV from the flux, and NIOSH research on welding fume and manganese has driven respirator guidance for decades. Gas processes add high-pressure cylinders, where NFPA training requirements come in. Confusing the processes means confusing the controls. Stick is one wrench in the arc welding toolbox, so when precision counts, name the tool.

Arc Welding Family: Other Processes To Know

This is the part that settles most of the arguments. Arc welding is not a single process. It is a family, and every member shares one core idea: an arc forms between an electrode and the workpiece, the heat melts base metal, and the molten metal cools into a joint. Stick welding belongs to that family, but so do GMAW, GTAW, FCAW, and SAW, plus lesser-known members such as air carbon arc gouging.

Three questions separate one arc process from another: how the arc is shielded, what kind of electrode carries the current, and where the filler metal comes from. Answer those for a process and you can predict most of its strengths and weaknesses without opening a manual.

Process	Electrode & filler	Shielding	Where it wins	Trade name
SMAW	Flux-coated consumable rod	Slag from the coating	Field work, structural, shipyard	Stick / arc
GMAW	Continuous solid wire	Shielding gas	Production fabs, automotive, structural	MIG / MAG
FCAW	Tubular wire with flux core	Slag, sometimes plus added gas	Heavy plate, shipbuilding, field erection	Flux core
GTAW	Non-consumable tungsten plus separate rod	Inert gas	Thin gauge, aluminum, stainless, aerospace	TIG
SAW	Continuous wire under a flux blanket	Buried in granular flux	Long seams, pipe, heavy plate	Submerged arc

GMAW: The Production Workhorse

Gas Metal Arc Welding runs a continuous solid wire that carries the current and becomes the filler metal at the same time. A shielding gas, usually argon mixed with carbon dioxide for steel or pure argon for aluminum and stainless, keeps the atmosphere off the puddle. That wire feed is why GMAW dominates modern fabrication: high deposition rates, manageable spatter, and easy mechanization on long seams.

Transfer mode changes with the setup. Short-circuiting transfer suits thin material and short welds, spray transfer handles thicker plate and stainless, and pulsed spray produces a controlled, low-spatter bead many shops prefer. Because parameters are tightly coupled to wire diameter, gas, and amperage, GMAW asks more setup knowledge than stick welding, then runs far faster once dialled in. On aluminum the gas choice and machine setup change completely, and this aluminum MIG welding guide covers that shift in detail.

GTAW: The Precision Process

Gas Tungsten Arc Welding replaces the consumable wire with a non-consumable tungsten electrode. The tungsten only conducts the arc; filler metal is added by hand from a separate rod or wire. Shielding comes from an inert gas, normally argon, and helium when heavier heat input is needed on aluminum.

That arrangement gives a clean, slag-free, highly controllable arc, which is why GTAW is the standard for thin-gauge stainless, aluminum, and aerospace components. It is also slower and costlier. The same qualities that make TIG beautiful, arc control and repeatability, make it the preferred method in critical work. The aerospace TIG welding guide shows how tightly those standards are written.

FCAW: Heavy-Duty Wire Feed

Flux Cored Arc Welding looks like GMAW, but the wire is a tube filled with flux. As the wire feeds, the flux decomposes and forms a slag layer over the bead, which is what lets FCAW run on a simple gas shield or, in self-shielded versions, no external gas at all. Self-shielding is a real advantage outdoors on bridges, pipelines, and structural steel, where gas cylinders are a nuisance.

FCAW deposits faster and penetrates deeper than GMAW, so it turns up on ship hulls, pressure vessels, and heavy structural plate. Aluminum flux core wire exists but demands far tighter control than steel, which is why aluminum flux core welding comes with its own set of rules.

SAW: The Mechanized Heavyweight

Submerged Arc Welding has the highest deposition rate in the family. The arc burns under a blanket of granular flux, the wire feeds continuously, and spent flux is vacuumed up and reused. Because the arc is buried, heat stays in the weld instead of escaping into the air, and the finished bead comes out smooth with very little spatter.

SAW is almost always mechanized or automated, working long, straight seams: pipeline girth welds, large plate seams, ship hulls, and pressure vessel work. AWS classifies these processes under its welding procedure standards, where the formal definitions live, so the American Welding Society is the reference if you want the technical version.

The takeaway is simple. When someone says “arc welding,” they have named the category, and there are at least five solid processes inside it. When they say “stick,” they have named one specific process, SMAW, with its own shielding slag, consumable electrode, and field-friendly habits. Both statements can be true at once, and the useful habit is asking which member of the family the job actually calls for.

Benefits, Limitations, And Challenges Of Each Approach

Comparing the two terms is like comparing one car brand with driving in general. Stick welding is a single process inside the arc welding family, so it inherits many of that family’s strengths and adds a few quirks of its own. The fair comparison is process against process.

Portability and Setup: Where Stick Pulls Ahead

SMAW is famous for portability and outdoor use with minimal equipment. A stick welder needs a power source, an electrode holder, and a consumable electrode. That is the whole list: no cylinder to haul, no flowmeter to dial in, no wire feeder to thread, and no gas line to snag on a scaffold plank.

Other arc processes want more infrastructure before the first arc strikes. GMAW and FCAW need wire feeding, and the gas-shielded versions need shielding gas with regulators and flow control, an extra system to manage on a remote site. GTAW adds a torch that wants water cooling for sustained work, plus filler rod and its own shielding gas. SAW runs continuous wire feed under a blanket of granular flux. Understanding how air and shielding gas welding setups change the logistics explains why stick remains the field favourite.

Weather matters too. The electrode coating decomposes in the arc and creates its own protective atmosphere, so stick tolerates crosswind or a freezing morning far better than a gas-shielded process whose delivery lag leaves the puddle exposed.

Versatility and Material Range

SMAW forgives surface condition and position. It runs in all positions, handles light rust and mill scale that would make a MIG gun sputter, and suits repair work on heavy plate, structural members, pipe, and castings.

Materials are where the family divides. SMAW covers carbon steel, stainless steel, and nickel alloys with the right electrode, but it cannot weld aluminum or magnesium, which belong to separate process families. For aluminum work, our guide to aluminum flux core welding covers what works instead. Stick is also slower. Deposition rates fall below GMAW, FCAW, and especially SAW, and because the coating turns to slag, every pass needs chipping. On long production runs that is often the deciding factor. The advantages of stick welding are worth reading alongside these trade-offs.

Training and the Skill Curve

Beginners assume stick is harder than MIG. It has more variables, but those variables teach fundamentals. Arc length, travel speed, and puddle control live in the welder’s hands, and the reward is someone who understands what an arc does. GTAW is generally regarded as the most technically demanding process, while GMAW is the most forgiving of setup errors. Choosing electrodes for the base metal and position is covered in our all-position welding rod guide.

Quality Control and Repeatability

SMAW output depends heavily on operator technique. Electrode tilt, arc length, weave, and slag cleanup all change the outcome between two welders running the same joint, so inspection leans on visual checks and the destructive testing defined in codes such as AWS D1.1. GMAW lets you lock in wire feed speed, voltage, and travel speed on the machine, making welds more repeatable from operator to operator. The trade-off is more settings to configure and more equipment to maintain.

Environmental and Safety Factors

SMAW is not the cleanest process in a shop. The flux coating produces substantial fume and spatter, and welding stainless or chrome-bearing alloys introduces hexavalent chromium, which OSHA regulates with a permissible exposure limit of 5 micrograms per cubic meter. Galvanized coatings add zinc oxide fume, the classic trigger for metal fume fever.

That is why fume extraction and local exhaust ventilation matter, and why respirators, correct eye protection, and hot work fire watch procedures are non-negotiable. Welding fume exposure guidance comes from NIOSH, and hot work fire protection practices from NFPA guidance.

Operator Challenges, Side by Side

Factor	SMAW (Stick)	Other Arc Processes
Setup	Power source, holder, electrode	Adds gas supply, regulators, wire feeder, sometimes torch cooling
Outdoor use	Excellent, self-shielding	Gas shield is vulnerable to wind and cold
Deposition rate	Lower, slag removal required	Higher on GMAW, FCAW, and SAW
Fume and spatter	Highest of the common processes	GMAW moderate, GTAW low, SAW low but needs extraction
Repeatability	Operator dependent	More machine controlled, especially GMAW
Materials	Steel, stainless, nickel alloys	Broader, including aluminum via MIG and flux core routes

Every process has a signature annoyance. For stick it is electrode changes, restriking, and slag cleanup. For gas processes it is cylinders, shielding failure, and gas cost. For SAW it is flux handling and positioning the joined parts. The right choice is usually the one whose weakness you can live with on that specific job.

Common Mistakes, Troubleshooting, And Practical Solutions

Choosing the right process only gets you halfway. Nearly every failed weld traces back to a few recurring errors: an arc held too long, a rod left out in the damp, a bead cleaned badly, or a joint that was never clean. Because these failures repeat, they can be tracked down.

Getting the Arc Length Right

Arc length is the most important variable you control by hand in stick welding. Too close and you get a stubbing condition: the tip touches the weld pool, the arc breaks, and you see erratic spatter, a cold-looking bead, and trapped gas. Too long and the arc wanders and spatters heavily, burning a wide, flat bead with undercut along the toe.

The rule of thumb is a short arc of roughly a quarter inch, about 6 mm, from electrode tip to work. Shorter is required out of position, and vertical-up work especially punishes a long arc. Angle matters too: a drag angle of roughly 10 to 20 degrees stabilizes the arc, while a push angle pushes slag ahead of the pool rather than lifting it. Our all-position welding rod guide shows how the same rod behaves flat, vertical, and overhead.

Wet Electrodes and Porous Welds

Improper electrode storage is one of the most common causes of porosity. Paper packaging is not waterproof, so electrodes left in a humid shop, on damp concrete, or in a truck bed overnight absorb moisture. That moisture becomes hydrogen during welding, and hydrogen in the pool produces porosity, fisheye defects, undercut, and in severe cases hydrogen-assisted cracking.

Cellulosic E6010 and E6011 tolerate damp far better than low-hydrogen E7018 and E7016, which are hygroscopic and need controlled handling in heated rod ovens or sealed containers with desiccant. Follow the manufacturer’s storage requirements exactly. The American Welding Society filler metal specifications and welding codes set standard practice for electrode selection and storage. If a rod has been exposed to moisture, do not simply re-dry it; many low-hydrogen electrodes are not intended to be re-dried, so check the data sheet or replace them. Our alloy steel welding electrode guide covers selection and safety notes.

Slag Inclusions

Slag inclusion means slag got trapped in the weld. In SMAW the flux coating decomposes into a molten glassy layer that floats on the pool; if it is not lifted and removed between passes, it gets welded over.

• Chipping too fast or too close to the bead damages penetration of the previous pass. Use a chipping hammer or wire brush, staying clear of the toe.
• Current too low leaves a cold, sluggish pool that swallows slag. Check the amperage range on the rod packaging.
• Weaving too quickly traps slag between the weave crests. Slow down and let the pool clean.
• Incorrect work angle lets slag run ahead of the puddle. Tilt the work so slag falls away.
• Arc held too long generates excessive slag and a wide, dirty bead.

For heavy spatter, stubborn slag, or a bad pass, air carbon arc gouging is the fast option. Our air arc welding and gouging guide covers the process and its safety requirements.

Porosity That Has Nothing to Do With the Rod

If the electrode is dry and the bead still comes out full of holes, look elsewhere. Dirty base metal is the usual culprit: rust, mill scale, paint, oil, cutting fluid, and moisture all release gases as the pool forms. Clean to bright metal with a grinder, and use a dedicated welding aluminum cleaner on aluminum, since the oxide film reforms in minutes.

On gas-shielded processes, porosity also comes from shielding gas problems: wrong flow rate, a hose leak, a cold gun, or a draft across the work. Aluminum punishes contamination and a disturbed shielding envelope alike, so our aluminum MIG welding guide focuses on preparation and gun work.

Quick Symptom Reference

Symptom	Likely Cause	Corrective Action
Heavy spatter	Long arc, wrong polarity, excess voltage	Shorten arc, confirm polarity, check settings
Undercut at the toe	Fast travel, high amperage, long arc	Slow down, trim amperage, shorten arc
Lack of fusion	Cold joint, fast travel, low heat	Grind clean, match amperage to thickness
Excessive reinforcement	Slow travel, high amperage	Speed up, reduce amperage
Fisheye porosity	Damp electrode, dirty base metal	Dry or replace rod, clean to bright metal
Slag in the bead	Poor chipping, low current, fast weaving	Clean between passes, correct amperage

A Repeatable Troubleshooting Routine

When a weld goes wrong mid-job, resist changing three settings at once. Work through this order instead:

1. Stop and assess. Note the symptom, its location, and when in the pass it appeared.
2. Check consumables. Is the electrode dry, in date, and correct for the joint?
3. Check the joint. Grind out questionable material; confirm fit-up and root opening.
4. Check the machine. Verify amperage against the electrode range, plus polarity and ground clamp placement.
5. Re-test on scrap. Make a short practice bead with the same settings.
6. Document the fix. A one-line note in your log saves the same diagnosis next week.

If the same defect keeps returning after all of that, the problem may not be technique at all. It may be the procedure. ASME codes and ANSI standards often require a qualified welding procedure, and code work that does not match its WPS is a defect no matter how good the bead looks. When in doubt, write a procedure, test it on coupon, and get it qualified.

Practical Tips For Choosing Between The Terms And Processes

Stick welding is SMAW, and SMAW is one of several arc welding processes. What do you do with that knowledge? Reading a spec, choosing a process for a repair, or talking shop all demand one skill: matching the right word to the right situation. The words matter less on the floor than most welders think and far more on paper, because the same sentence can be clear to a crew and dangerously vague to an inspector.

Which Term To Use, And When

Start with the most precise term and step down only as far as you need to.

• Use “SMAW” when precision matters. WPSs, quality assurance plans, code documents, inspection reports, and qualification records all call the process by its designation, so anything that must survive an audit should say SMAW. The American Welding Society publishes the codes behind that documentation, and they name processes by letter designation, not trade name.
• Use “stick welding” on the floor. In the shop, on the trailer, in the field, and with other trades, “stick” lands instantly. A supervisor saying “set up for stick” is unambiguous on site.
• Use “arc welding” only as a category label. Save it for training material, safety orientation, shop manuals, and talking to someone outside the trade. It also fits the sentence “arc welding is a broad category that includes SMAW, GMAW, GTAW, FCAW, and SAW.”

Some people use “arc welding” loosely to mean stick, especially in regions where stick dominated for decades. Being right about the taxonomy is no reason to correct a shop foreman mid-conversation. Correct it in the document, not in the argument.

How To Read A Job Specification

Job specs are where terminology mistakes get expensive. Four habits will save you grief.

1. Find the process designation and filler metal. Specs pair a letter code with a classification, such as SMAW with an E60XX electrode or GMAW with ER70S-6 wire. That classification defines strength, ductility, and impact behavior.
2. Find the joint design. AWS D1.1 for structural steel, AWS D1.6 for stainless, and API 1104 style codes each carry their own joint details, and the joint design decides whether your process can make the required weld.
3. Check the essential variable restrictions. Codes limit layers and passes in certain joints or require certain positions to be qualified first. ASME codes for pressure vessels and boilers are the most unforgiving, which is why a qualified procedure matters there.
4. Read the supporting documents. If the spec calls up a WPS, weld to that procedure, not your habit. WPSs set amperage range, voltage, travel speed, preheat, interpass temperature, filler metal, shielding, and cleaning, and deviating can push a procedure outside its qualified range.

Picking A Process For The Job

Process selection comes down to four inputs: material, joint design, environment, and code requirements.

Factor	What It Pushes You Toward
Material	Carbon and low alloy steel: SMAW or GMAW. Stainless: GTAW or SMAW with a stainless electrode. Aluminum: pulse MIG or TIG, never SMAW with a steel electrode. Aluminum MIG welding and alloy wheel repair show why aluminum needs its own filler and gas.
Joint design	Thin material and light fabrication favor GMAW for speed. Irregular or repair joints with tough access favor SMAW. A flange or nozzle can make stick the only realistic option.
Environment	Wind and weather outdoors: SMAW shrugs it off, since shielding comes from the flux. Indoor production needing repeatability: GMAW, FCAW, or automated SAW win on speed and consistency.
Code requirements	Codes often permit several processes but restrict each. Check qualified positions, heat input limits, and preheat requirements before committing.

When Stick Is The Right Answer

Stick remains the right tool surprisingly often. It is the most portable arc process there is: a power source, an electrode holder, and an electrode, with no gas cylinder, no wire feeder, and no hoses running back to a machine. That makes it standard for field repairs, utility work, ship repair, pipeline work, structural erection, and any remote site. It also tolerates dirty or poorly prepared steel and imperfect technique better than most people expect. For a student, stick teaches arc control, joint reading, and heat management without adding a machine to the learning curve. The advantages of stick welding cover this in depth.

When Something Else Is The Right Answer

The case against stick is speed, not quality. You fill a joint one pass at a time with an electrode you have to stop and change. For production throughput and repeatable deposits, use GMAW, FCAW, or SAW; for thin, precise, high quality work where appearance matters, GTAW; and for heavy plate and long joints in a shop, nothing matches SAW deposition rates.

If the job is aluminum, the conversation shifts entirely. Aluminum needs a dedicated electrode or wire, clean preparation, and the right shielding gas, and those three things are where most aluminum weld failures begin. Before welding aluminum, work through how to prep aluminum for welding, and understand the difference between aluminum flux core welding and aluminum flux welding before you pick one.

Finally, Do Not Skip The Safety Basics

Whichever process you choose and whichever word you use for it, the fundamentals do not change. Ventilation matters enormously with stick because the flux coating produces fume, and fume contains metal particles you do not want in your lungs, so a fume extraction unit is not optional on a repeat job. Do not weld in a confined space without proper extraction and OSHA-compliant atmospheric testing. Remember that hot electrode stubs land on the floor and start fires, and that stick welding often runs dual-voltage at high amperage, so grounding and electrode holder condition matter. NFPA electrical safety standards and NIOSH guidance on fume and welding hazards are worth bookmarking.

Speak the shop language on the floor, write the code language on the paper, and let process choice follow material, joint, environment, and code, in that order. Say “SMAW” in the procedure and “stick” in the conversation, and you will never be the welder who guessed wrong about what the drawing meant.

Conclusion: The Final Verdict

After going through the science, the equipment, the rest of the arc family, and the day to day challenges of the trade, the answer to the original question is incredibly straightforward. Arc welding is not the same as stick welding.

Arc welding is the overarching category of welding processes that create a weld by utilizing an electric arc to generate the heat needed to fuse metal. Stick welding is a single process within that category, and its official name is Shielded Metal Arc Welding, or SMAW. The trade name “stick” simply comes from the flux covered consumable electrode that is used for it. With that being said, both terms can be correct in conversation, but only one is precise.

Think of it this way: every stick welder is doing arc welding, but not every arc welder is doing stick welding. Processes such as Gas Metal Arc Welding, Gas Tungsten Arc Welding, Flux Cored Arc Welding, and Submerged Arc Welding are all arc based processes, yet they each require different equipment, shielding methods, and skill sets to run correctly.

Why This Distinction Matters On The Job

Knowing the difference between a category and a specific process is more than just technical trivia. Terminology matters for code compliance and clear communication. When reviewing a weld procedure, job specification, or inspection checklist from organizations such as the American Welding Society, the process will almost always be listed by its proper code designation, such as SMAW. If a welder, foreman, or inspector is under the assumption that “arc welding” can be interchanged with any process, critical details can be missed.

This is especially true when factoring in workplace requirements. Many job sites must also follow general safety obligations set by OSHA for electrical work, ventilation, and personal protective equipment. These requirements are not applied to a vague phrase, they are applied to the specific process being performed and its known hazards.

The Strength Of Stick To This Day

With all of the modern processes available, stick welding has never lost its place for a reason. Its portability, tolerance for outdoor conditions, and ability to be used on many uncleaned or weathered surfaces keeps it in constant rotation, especially for repairs and field work. These are a few of the reasons that still contribute to the advantages of stick welding to this day. Even with the rise of more automated processes, there are still plenty of joints that a stick welder can get to with nothing more than a machine, leads, and a box of electrodes.

However, the tradeoff will always be the same. The convenience that makes SMAW so versatile can also make quality control more finicky, as factors such as moisture in electrodes, arc length, and slag removal all need to be taken seriously to avoid common defects.

The Final Takeaway

For everyday conversation on the shop floor, calling it “stick welding” is perfectly acceptable. For blueprints, procedure qualifications, inspections, or any form of written communication, call it by its correct designation. Knowing the difference between a category and a specific process prevents miscommunication on the job.

So the next time the debate comes up, you can settle it with confidence. Arc welding is the family. Stick welding is one of its oldest, toughest, and most reliable members. Use the broad term when speaking generally about arc based work, and use SMAW or “stick” when speaking about that process specifically. That small bit of precision goes a long way towards keeping jobs clear, consistent, and code compliant.

Frequently Asked Questions

Is stick welding the same thing as arc welding?

Not exactly. Arc welding is the broad category of processes that use an electric arc to create welds. Stick welding is the trade name for Shielded Metal Arc Welding (SMAW), which is just one of many arc welding processes.

Are all arc welders stick welders?

No. A ‘stick welder’ is a machine commonly configured for SMAW, however many arc welding machines can run other processes such as FCAW or can be multi-process machines. The term describes the process being ran more so than every arc machine.

What is the official name for stick welding?

The official American Welding Society designation for stick welding is Shielded Metal Arc Welding, abbreviated as SMAW.

Why do so many people say ‘arc welding’ when they mean stick welding?

For many years, SMAW was the most common and accessible arc process, so in everyday speech the category name was often used to refer to the specific process. This has led to the widespread, albeit imprecise, terminology.

Can I say arc welding on a job application if I only know stick welding?

It can be accurate in a general sense, however it is much more precise to list the specific process, such as SMAW or ‘shielded metal arc welding’. Many employers and inspectors prefer the exact process designation.

Is MIG or TIG considered arc welding?

Yes. Both Gas Metal Arc Welding (GMAW, commonly MIG) and Gas Tungsten Arc Welding (GTAW, commonly TIG) are arc welding processes, as they both utilize an electric arc as their heat source.

Do codes ever require the process name?

Yes. Welding codes and specifications almost always require the specific process designation, such as SMAW, GMAW, or GTAW, as opposed to the vague term ‘arc welding’.

Which is easier to learn, stick welding or other arc processes?

This varies for each welder, however SMAW is often taught as an introductory arc process due to its simplicity, however it comes with its own challenges such as slag removal and electrode manipulation. Each arc process has its own learning curve.
