NAVSEA Welding Certification: TP-248 Explained

A fabrication shop wins its first Navy subcontract, and the owner assumes the welders’ AWS cards will be enough. Three weeks later the first procedure is rejected before a single arc is struck, because nobody can produce a Procedure Qualification Record. That gap between what welders think certification means and what NAVSEA actually requires is where most first-time Navy work goes wrong.

What NAVSEA Welding Certification Actually Means (And What It Does Not)

For many shops, landing their first Navy subcontract seems like the finish line. With AWS cards in hand and years of structural steel under their belts, it’s assumed the welders are ready. However, all it takes is one kicked-back procedure for the reality to set in: the welders may be skilled, but without the required paperwork, the job cannot start.

This distinction between a general welding certification and NAVSEA compliance is the most common point of failure, and it’s one that needs to be understood before any of the rest of this guide comes into play.

NAVSEA Doesn’t Certify Welders

The biggest misconception is that there is a NAVSEA card to obtain. There isn’t. The Naval Sea Systems Command does not test, issue, or track individual welder certifications. Instead, it creates the requirements and audits whether a shop has followed them.

Those requirements are laid out in NAVSEA Technical Publication S9074-AQ-GIB-010/248, better known as TP-248. This document governs the qualification of welding and brazing procedures, along with the welders, welding operators, brazers, and brazing operators that use them. The full publication can be viewed here.

TP-248 replaced MIL-STD-248, which was cancelled by the Defense Logistics Agency on 28 August 1997, a fact that can be verified through the ASSIST database. With that in mind, any reliance on MIL-STD-248 is an immediate red flag. Under TP-248, it is the employer, not NAVSEA, that qualifies and certifies its personnel. This places the burden of proof onto the shop, and with it, the full weight of an audit.

Procedure Qualification and Performance Qualification Are Two Separate Requirements

All compliance under TP-248 stems from one split: procedure and performance. Section 4 covers the first, and Section 5 covers the second. Both must be satisfied with traceable evidence.

• Procedure Qualification (PQR/WPS): Proves that a specific welding method with its variables will produce a sound weld. This is backed by a Procedure Qualification Record and a Welding Procedure Specification.
• Performance Qualification (WPQ): Proves that a specific welder or operator can execute that qualified procedure in the required position, material, and thickness. This is backed by a qualification record and a written certification from the employer authorizing them to do so.

Neither can compensate for the other. An unqualified procedure will fail regardless of the welder’s skill, and an unqualified welder will fail regardless of how sound the procedure is.

When TP-248 Applies

TP-248 only applies when it is specified by the applicable fabrication document. This single conditional phrase determines the entire scope of work. Commonly, it will reach naval shipyards, prime contractors, subcontractors down the chain, and commercial job shops whose Navy-related purchase order invokes it.

It does not automatically apply to purely commercial work, private structural steel, or hobby fabrication. Even for commercial marine work, such as projects involving aluminum boat welding, TP-248 may not be required unless contractually invoked.

Qualified, Certified, Certificated, or Approved?

These terms may look synonymous, but under TP-248, they mean very different things.

Term	Meaning Under NAVSEA Compliance
Qualified	The required test has been welded, examined, and passed against the applicable variables.
Certified	The employer has signed written authorization for a qualified individual to weld to a specific procedure.
Certificated	Typically refers to a third-party card, such as an AWS card. This is useful commercially, but not a substitute for employer qualification under TP-248.
Approved	A determination by the authorized representative or customer that a procedure, program, or submittal is acceptable.

The Contract Is The Switch

Ultimately, the switch for compliance isn’t the material, the joint, or the skill level of the welder. It’s the contract. If TP-248 is not invoked by the governing drawing note, specification, or Standard Item, it does not apply. If it is invoked, it applies in full, including any revisions and change notices in effect on the contract date. With that in mind, the first document to read for any potential Navy job should always be the contract clause, not the standard itself.

The Document Stack: TP-248, TP-278, MIL-STD-1689 and the Rest

NAVSEA welding requirements rarely live in one book. They sit in a family of documents, each answering a different question. One tells you how to prove a procedure and a welder are capable. Others tell you what the finished weld must look like, how the joint should be designed, and how an inspector should judge a discontinuity. Knowing which document governs which question is the first practical skill in Navy fabrication, because citing the wrong one in a procedure or an inspection report invites a rejection before anyone strikes an arc.

TP-248: The Qualification Document

S9074-AQ-GIB-010-248, almost always called TP-248, is the requirements document for welding and brazing procedure and performance qualification. It explains how to build a Welding Procedure Specification, how to qualify it with a Procedure Qualification Record, and how to test a welder or brazer. It is a qualification rulebook, not a fabrication specification. Passing TP-248 proves capability; it does not by itself set the acceptance criteria for production work.

TP-278: Fabrication for Machinery, Piping and Pressure Vessels

S9074-AR-GIB-010/278, or TP-278, covers requirements for fabrication welding and inspection, plus casting inspection and repair, for machinery, piping and pressure vessels. This is the document a pipe shop, pump room or pressure-vessel fabricator lives inside. It addresses joint preparation, fit-up, welding practice, inspection and repair. If the work is a seawater line, a hydraulic reservoir or a cast valve body, TP-278 is usually the governing fabrication document, while TP-248 sits behind it proving the procedure and the welder.

MIL-STD-1689: Ship Structure

MIL-STD-1689 addresses fabrication, assembly and inspection of ship structure. Hull plating, decks, bulkheads, foundations and similar structural work fall into its world. The distinction matters: MIL-STD-1689 tells you what the structure must satisfy, while TP-248 tells you how the procedure and personnel were qualified. A strong PQR does not substitute for structural inspection requirements, and a clean structural inspection does not validate an unqualified welder.

The Supporting Standards

Several other documents fill specific gaps. MIL-STD-22 covers welded joint design, so designers and detailers use it to select joint configurations. T9074-AS-GIB-010/271 covers nondestructive testing methods, while MIL-STD-2035 sets the acceptance criteria those methods are judged against. In plain terms, one document tells the technician how to shoot the radiograph or perform the ultrasonic scan; the other tells the examiner whether the indication is acceptable. Confusing methods with acceptance criteria is a classic documentation error.

Standard Item 009-12: The Contract-Level Index

NAVSEA Standard Item 009-12 is the contract item that points to the right paragraph for each material class. The FY 26 package lists welder and brazer qualification against TP-248 paragraph 5 and welding procedure qualification against paragraph 4, broken out by material class: carbon steel, HY-80/100 and HSLA-80, aluminum, stainless steel, copper-nickel and bronze. The material column is not decorative. Each class can carry different preheat, filler, testing or documentation requirements, so citing the carbon steel line for an HY-80 job is a substantive error, not a clerical one. Shops working aluminum should also understand how process choice affects qualification; our guide to aluminum MIG welding covers the practical side of that material family.

Document	What it governs	Typical user
TP-248	Procedure and performance qualification for welding and brazing	Welding engineer, QA, examiner
TP-278	Fabrication welding and inspection, casting inspection and repair for machinery, piping and pressure vessels	Shop QC, piping and mechanical engineers
MIL-STD-1689	Fabrication, assembly and inspection of ship structure	Structural QC, shipyard production
MIL-STD-22	Welded joint design	Designers, drafters, engineers
MIL-STD-2035	Nondestructive testing acceptance criteria	NDT inspectors, QC
T9074-AS-GIB-010/271	Nondestructive testing methods	NDT technicians, examiners
Standard Item 009-12	Contract pointer to qualification paragraphs by material class	Estimators, project managers, QA

The clean mental model is this: TP-248 tells you how to prove a method and a person are capable. TP-278, MIL-STD-1689 and the NDT standards tell you what the finished weld must be. A procedure can pass every mechanical test and still produce work that fails visual or ultrasonic acceptance. Both sides of that equation have to be satisfied.

Procedure Qualification: Building a WPS and PQR That Survive Review

Procedure qualification is where a Navy fabrication job either becomes real or falls apart. It is also the part of TP-248 that rewards preparation more than welding skill. The goal is not to produce one beautiful test coupon. It is to prove, with records, that a documented set of variables will reliably produce a sound weld in production.

TP-248, formally S9074-AQ-GIB-010/248, covers manual, semiautomatic, automatic, machine and robotic welding and brazing of ferrous, nonferrous and dissimilar metals. Section 4 sets out the procedure qualification path. The governing principle is simple: a procedure must be qualified by both nondestructive and destructive testing before it can support production welding.

That order matters. You write the procedure, you weld the coupon to it, you test the coupon, and you record what actually happened. Skipping ahead to production and backfilling the paperwork later is the fastest way to lose a review.

What the WPS Must Say

A Welding Procedure Specification is the recipe. It has to be specific enough that a competent welder can follow it without guessing, and detailed enough that a reviewer can see exactly what was qualified. At minimum, expect the WPS to identify:

• Base metal specification, grade, and qualified thickness range
• Filler metal classification and size
• Shielding gas or flux, including flow rate or composition
• Current type, polarity, and amperage range
• Voltage range and travel speed range
• Welding position and progression direction
• Preheat, interpass, and post-weld heat treatment limits
• Cleaning methods and interpass cleaning
• Joint design, root gap, and fit-up tolerances
• Pass sequence, back gouging, and root preparation for multi-pass work

Vague ranges are a common review failure. A WPS that says “440–600 amps” without explaining how the welder selects within that range is not much of a procedure. The same applies to aluminum work, where cleaning and wire handling can change the result as much as amperage. If you are qualifying aluminum, the practical details in this aluminum MIG welding guide are a useful reminder that procedure variables include preparation, not just machine settings.

A good test: hand the WPS to a welder who has never seen the job. If they have to ask you what gas, what position, or how much preheat, the document is not finished.

What the PQR Must Prove

The Procedure Qualification Record is the evidence. It records the actual variables used to make the qualification coupon, the test results, and the acceptable ranges that follow from those results. The coupon is welded using the proposed WPS. Before anyone cuts it apart, it receives the applicable nondestructive examination, typically visual inspection plus radiographic or ultrasonic testing, and penetrant or magnetic particle inspection where required.

Destructive testing usually includes tensile tests and bend tests, with impact testing added where the specification or material demands it. The PQR must show that the tested specimen met the acceptance criteria, not merely that it was welded. If a test fails, the procedure fails. There is no “close enough” column.

Two PQR habits separate clean submittals from painful ones. First, record the real numbers from the actual coupon, not the nominal ranges from the WPS. Second, keep the heat input, preheat, and interpass readings with the record. Reviewers look for consistency between the WPS, the PQR, and the test reports, and mismatches are treated as documentation errors at best and invalid qualifications at worst.

Essential Variables Are Not Suggestions

Essential variables are the conditions that, if changed, invalidate the qualification. They typically include base metal group, thickness range, filler metal classification, welding process, position, current type and polarity, preheat and interpass temperature, and heat input. Change one outside its qualified range and the procedure is no longer supported by the PQR. You need a new coupon and a new record.

This is where production pressure causes trouble. A shop runs short on the qualified filler metal, substitutes a similar classification, and keeps welding. The weld may pass inspection, but the paperwork no longer matches the qualified procedure. During a survey, that is a finding regardless of how the weld looks.

Repairs deserve the same discipline. A repair procedure is a procedure, with its own variables, limits, and often its own qualification. “We will just grind it out and weld it back” is a plan, not a qualified process.

When the WPS, the PQR, and the test records line up, review becomes a reading exercise rather than an argument. That is the whole point of procedure qualification: the welding is proven once, in a controlled coupon, so production does not have to prove it again on the ship.

Welder Performance Qualification: What Happens on Test Day

Procedure qualification proves that a method works. Performance qualification proves that a person can execute that method under the conditions the job will actually impose. That distinction matters because a welder’s performance qualification is not a general license to weld anything. It is tied to the process, position, thickness range, and base material tested, along with the essential variables recorded on the supporting procedure.

One Test Does Not Cover Everything

A welder who passes a flat-position groove test on quarter-inch carbon steel has demonstrated something useful, but not everything. Under Section 5 of TP-248, performance qualification is specific to:

• Process: SMAW, GTAW, FCAW, GMAW, and each variant covered by the procedure.
• Position: flat, horizontal, vertical, overhead, or a fixed-pipe combination.
• Thickness: the qualified range, not every plate in the shop.
• Base material: the material group tested, not a different alloy with similar-looking weldability.

Change one of those variables and the old test may no longer support the work. That is why a welder qualified on stainless tube with a GTAW root cannot automatically switch to FCAW on thick HY-80. The process changed, the material changed, and the heat input rules changed with them. Material-specific procedures also matter when you move into aluminum; the same logic that governs steel applies to aluminum MIG welding, where cleaning, filler selection, and position control all affect whether a test coupon passes.

The Test Assembly and Numbered Tests

TP-248 lays out numbered qualification tests that pair a process with a product form and position. The exact test number matters because it defines what the coupon must look like, how it is welded, and what the resulting qualification covers. Most tests use a groove-welded plate or pipe assembly, although the standard also addresses fillet and other product forms where applicable.

Fixed-position and restricted-position tests are the ones that separate production welders from coupon specialists. In a flat test, the assembly can be turned so the weld stays in the easiest position. In a fixed-position test, the coupon stays put and the welder has to work vertical, overhead, or around a pipe without rolling it. Restricted-position tests add access limitations. A welder who has only run flat work should practice the exact test configuration before showing up, not assume that good shop welds will translate. The all-position welding rod guide is a useful refresher on how position changes technique, though the qualification itself is controlled by TP-248 and the applicable procedure.

After welding, the coupon goes through a sequence. Visual inspection comes first, because a test with obvious undercut, porosity, or an incomplete joint does not need to proceed to expensive examination. Where the procedure or contract requires it, the weld is then examined by radiography or ultrasonography. Destructive testing follows, typically bend tests and, where specified, tensile or impact tests. The acceptance criteria come from TP-248 and the referenced NDT standard, not from the examiner’s personal preference.

Supporting Requirements Beyond the Weld

A passing coupon is only one part of qualification. AWS guidance on NAVSEA qualification notes that each welder must complete a welder workmanship training course and pass a written examination covering the applicable NAVSEA standards, with the workmanship examination renewed every three years. The same guidance states that the welder must pass a visual acuity examination every year, and that the qualification program must be audited every two years and certified by the examiner as fully functional. These are not optional extras. A welder with strong hands and no documented workmanship training is still an incomplete file.

The Production-Weld Alternative

TP-248 permits an alternative to the standard test coupon: qualifying a welder by making a production weld that is radiographically or ultrasonically inspected and found satisfactory. This can save time on a real job, but it comes with a hard condition. Permission from the authorized representative must be obtained before the individual begins production work. You cannot weld first, discover the weld passed inspection, and then ask to count it as a qualification. The production weld must also fall within the variables being qualified, so the paperwork has to be arranged before the arc starts.

Records and Test-Day Preparation

The qualification test record is what turns a good weld into evidence. At a minimum, TP-248 expects the welder or operator identification, date of test, qualification test number, process, position, base material type, and filler metal. Most complete programs also attach the test results, examiner signature, and a clear reference to the supporting WPS and PQR.

Test day is not the place to improvise. The welder should know which test number applies, which position is fixed, and which variables the examiner will record. That preparation is what keeps a qualification from becoming an expensive retest.

Keeping Qualification Alive: Continuity, Records and Audits

Passing the test is the easy part. What quietly undoes more Navy welding programs than bad technique is what happens in the eleven months after the coupon is bent and signed off. A qualification is not a diploma hanging on the wall. It is a living claim that the welder is still doing the work, still seeing well enough to do it, and still backed by paperwork that matches what actually happened in the shop.

Continuity: The Clock Nobody Watches

Performance qualification stays valid only while the welder keeps using the process. TP-248 handles this through a maintenance rule, and the revision history matters here: the periodicity for maintaining welding and brazing performance qualification was extended from three months to six months. That change gave shops breathing room, but it also created a false sense of safety. Six months is not long when a welder rotates through fitting, layout, and repair work.

What counts as qualifying use? Welding with the same process, in the qualified position and thickness range, on production work or a documented practice coupon, within the maintenance window. The continuity log is the evidence. It should capture the welder’s name and ID, the process and position, the WPS number, the date of each qualifying use, the part or job number, and the supervisor’s verification. A log with dates but no job references is a log an examiner will question.

Now the scenario that catches people. A welder qualifies in June, gets pulled onto fitting for eight months, and comes back to the arc in February. The qualification lapsed. Nobody failed anything, and nobody did anything wrong technically, but the record now shows a gap. The fix is a requalification test, not a strongly worded memo. This is where marine work gets unforgiving, and it is worth reading broader guidance on marine welding processes and standards to see how tightly the whole chain connects.

What a Qualification Record Has to Contain

TP-248 requires welder qualification records to be accumulated and maintained, and it provides a suggested record format and data accumulation form. Use it. The record should identify the welder, the qualification test or production weld used, the process, position, thickness and material, the WPS and PQR it traces back to, the test results, the examining party, and signatures with dates. Traceability to the WPS and PQR is the spine of the whole file. If a reviewer cannot walk from the welder’s certificate to the procedure that supported it in under a minute, your filing system is the problem.

Store originals in a controlled location with a backup copy, retain them for the period the contract and TP-248 require, and keep them legible. Scans are fine if they are complete and indexed.

Here is the part welders dislike. The qualification belongs to the employing activity, not the individual. A welder moving to a new employer generally cannot carry the qualification along. The new shop must qualify that welder under its own program and its own WPSs, because the qualification is tied to the employer’s procedures and records. What travels is documented, verifiable experience, not the certificate itself.

Surviving the Audit

The audit cycle is predictable. AWS Inspection Trends guidance lists an annual visual acuity examination, a workmanship examination every three years, and a program audit every two years certified by the examiner. An examiner reviewing records looks for continuity gaps, expired eye tests, missing signatures, WPS revisions that no longer match the PQR, filler metal certifications, calibration records for gauges, and welders working outside their qualified range.

Maintenance Item	Frequency	Evidence
Continuity of use	Within six months	Dated continuity log with job references
Visual acuity examination	Annually	Examiner-signed eye test record
Workmanship examination	Every three years	Exam record tied to applicable standards
Program audit	Every two years	Audit report certified by the examiner

The shops that sail through reviews are not the ones with the thickest binders. They are the ones with a simple document control system: a master index, a revision log, one file per welder, one file per WPS-PQR pair, a calendar with the four dates above, and one person accountable for all of it. The controlling reference is always the contract and the current revision of the invoked publication, available through NAVSEA and the TP-248 document itself. Build the calendar, assign the owner, and the audit stops being an event and becomes a routine.

Materials and Processes That Drive Navy Qualification

Navy welding starts with a more demanding question than “can we weld this?” It asks what the base metal is, how much heat it will tolerate, and which qualified procedure applies. TP-248 applies across ferrous, nonferrous and dissimilar metal welding and brazing, so one shop-wide procedure cannot cover a naval workload.

This is where the material columns in Standard Item 009-12 matter. They organize welder and procedure qualification by carbon steel, HY-80/100 and HSLA-80, aluminum alloy, chromium-nickel stainless steel, copper and nickel base alloys, silicon bronze and aluminum bronze. Move across a column and the governing paragraphs change with it.

Carbon Steel and the High-Strength Steels

Ordinary carbon steel is the easy part, comparatively. HY-80, HY-100 and HSLA-80 are not. These higher-strength steels demand low-hydrogen practice, controlled preheat and interpass temperatures, and a heat-input range that the procedure actually enforces. Electrode storage, exposure limits and re-drying records become part of the qualification trail, not workshop housekeeping. Choosing the right consumable is its own discipline; our guide to alloy steel welding electrodes explains the selection basics.

The risk driving all this control is hydrogen cracking, which can appear hours after a weld looks perfect. HY-100 welding under TP-248 depends on a PQR framework, WPS content and control of essential variables because the procedure is tied to that material and heat-input regime. A procedure qualified on mild steel does not transfer, and neither does a welder’s performance qualification.

Aluminum Alloys

Aluminum shows up in surface ship structures, decks and superstructures, and it punishes habits carried over from steel. The oxide layer melts at a far higher temperature than the metal beneath it, thermal conductivity pulls heat away quickly, and distortion is relentless. Porosity usually traces back to surface contamination or poor shielding, so dedicated stainless brushes, separate grinding wheels and proper cleaning matter before the arc starts.

GMAW and GTAW are common, with pulsed variants used to manage heat. A steel procedure and a steel welder qualification tell you nothing about aluminum. Filler selection, cleaning method, joint preparation and travel technique all change.

Stainless Steel and Copper-Nickel Piping

Chromium-nickel stainless steels bring corrosion resistance and their own traps: sensitization from excessive heat, distorted fit-ups, and contamination from carbon steel tooling. Lower heat input, matched filler and scrupulous cleanliness are routine expectations. Copper-nickel piping behaves differently again, with high thermal conductivity and a strong sensitivity to contamination in the joint area. GTAW roots are common where cleanliness and root control matter, but the qualified procedure still decides the details.

TP-248 also covers dissimilar metal joints and brazing. Those are not loopholes around qualification; they are separate qualification problems.

Why the Process Changes the Qualification

GTAW roots, FCAW restrictions, pulsed current and robotic welding each alter the essential variables. FCAW may be restricted by material class, position or toughness requirements. Pulsed processes change heat input and solidification behaviour. TP-248 addresses manual, semiautomatic, automatic, machine and robotic processes, so an automated or mechanized procedure needs its own qualification rather than inheriting a manual approval.

Material family	Typical process	Qualification headache
Carbon steel	SMAW, FCAW, GMAW, SAW	Hydrogen control and procedure range still apply
HY-80 / HY-100	SMAW, GMAW, FCAW, SAW	Preheat, interpass, heat input and hydrogen cracking
HSLA-80	GMAW, FCAW, SAW	Narrow heat-input window and toughness
Aluminum alloy	GMAW, GTAW, pulsed variants	Cleaning, porosity and distortion control
Cr-Ni stainless	GTAW, GMAW, SMAW	Heat input, contamination and filler matching
Copper-nickel	GTAW, GMAW	Thermal conductivity, cleanliness and fit-up

The practical rule is simple: match the procedure to the material group and the process, then prove it with the right PQR and performance test. Everything else is guesswork dressed up as experience.

The Seven Mistakes That Sink First-Time NAVSEA Programs

Most first-time NAVSEA failures are documentary, not metallurgical. The welders can weld. The shop simply cannot prove that the method and the person were qualified under the invoked contract documents. These seven mistakes account for a large share of pre-production rejections, and each one has a practical fix.

1. Assuming an AWS card satisfies the contract

A shop submits a welder’s AWS certification with its first WPS package. The reviewer asks for the employer’s performance qualification record and the supporting PQR. There is no answer. Result: rejected procedure package, a nonconformance report, and a schedule slip before fabrication begins. AWS certification is evidence of a test under a different system. NAVSEA requirements apply when the contract invokes them, so read the fabrication document and the applicable NAVSEA Standard Item 009-12 before promising anything. Fix: build a contract-to-document map and qualify through your own employer program.

2. Using a WPS from a previous employer with no PQR on site

A supervisor brings a familiar WPS from his last shipyard. The ranges look right, so the shop runs it. During review, the PQR is missing, the supporting tests belong to another company, and the essential variables cannot be traced. Result: the procedure is treated as unqualified, production stops, and requalification consumes weeks. A WPS without its PQR is a recipe, not proof. Fix: qualify the procedure under your own quality system, or purchase a standard WPS with the correct supporting documentation.

3. Qualifying in the wrong position or thickness range

A welder passes a flat test, then gets assigned to overhead work. The qualification does not cover the position, so the joint is outside the qualified envelope. Result: rework, a retest fee, and a revised welder list. Position and thickness are essential variables, not administrative details. The same principle applies when selecting consumables for restricted access; this all-position welding rod guide explains how position changes consumable behavior. Fix: test to the positions and thickness ranges the contract actually requires, including the awkward ones.

4. Letting continuity lapse by a few weeks

A welder spends eight months fitting and returns to welding just after the maintenance window closes. The qualification is no longer maintained. Result: the welder must be requalified before production work, which adds retest cost and removes a body from the schedule. A qualification lapses when the welder stops using the process for the maintenance interval, which is why shipyards and defense contractors keep continuity logs. Fix: track qualifying use monthly, not annually, and schedule a maintenance weld before the window closes.

5. Treating a filler substitution as a minor change

The specified electrode is out of stock, so the shop substitutes a similar classification. The weld passes visual inspection, but the filler classification is an essential variable. Result: the WPS is invalid for that joint, the weld becomes a candidate for removal, and the substitution triggers a nonconformance report. Filler selection is material-specific, as this alloy steel electrode guide illustrates. Fix: treat every filler change as a procedure change until the PQR or a qualified revision proves otherwise.

6. Running uncalibrated gauges and undocumented preheat

A crew uses a shop thermometer with no calibration sticker and records preheat as “adequate.” The examiner cannot verify the interpass or preheat limits, so the procedure is considered unsubstantiated. Result: rejected records, repeat inspection, and possible rework on hydrogen-sensitive joints. Fix: calibrate gauges on a schedule and record actual preheat and interpass readings against the WPS limits.

7. Treating records as paperwork to reconstruct later

A job shop finishes the work, then asks welders to sign qualification records from memory. Signatures, dates, and test results do not align. Result: a failed records review, withheld acceptance, and expensive reconstruction that may still be rejected. Fix: make record creation simultaneous with the work and store it under document control.

Mistake	Symptom	Fix
AWS card treated as contract qualification	No employer PQR or performance record	Map invoked documents and qualify internally
Borrowed WPS	Missing PQR and test traceability	Requalify or buy a documented standard WPS
Wrong position or thickness	Welder outside qualified range	Test to required variables
Continuity lapse	Maintenance window missed	Track use monthly and requalify early
Filler substitution	Essential variable changed	Approve through the PQR before use
Uncalibrated gauges	Preheat and interpass unverified	Calibrate and record actual readings
Late record reconstruction	Inconsistent signatures and dates	Document in real time under control

The pattern is consistent: each shortcut saves a day and costs a production week. Fix the system, not just the individual weld, and most of these failures disappear before the examiner arrives.

Building a Program: Cost, Timeline and the Practical Path In

By this point you know what has to be proven and who signs off on it. The question now is sequencing. Shops that struggle with NAVSEA work rarely fail because they misunderstood a clause; they fail because they tried to do everything at once, in the wrong order, and ran out of patience before the paper caught up with the welding.

Here is the part that surprises people: you do not have to be a naval shipyard to do this. NAVSEA Standard Item 009-12 and the qualification requirements it invokes apply to any activity that must meet them, including subcontractors who receive the clauses flowed down from a prime. That means a 20-person job shop can build a compliant program. It just cannot build it by accident.

The Realistic Sequence

Work through these steps in order. Skipping ahead is the single most common source of wasted money.

1. Read the contract and list every invoked document. Not the general spec. The actual fabrication document, its revision letter, and every standard item reference. If NAVSEA publications are not invoked, they do not automatically govern your weld.
2. Gap-audit what you already own. Pull every WPS and PQR in the building and check three things: does a PQR exist for each WPS, was it qualified to the revision named in the contract, and are the essential variables inside the range you actually weld?
3. Decide: qualify in-house or buy standard procedures. Detailed below, because this is where most of the money sits.
4. Sort out test facilities. Either build a dedicated test bay with controlled coupon prep, or contract with a lab for machining, NDT and mechanical testing.
5. Train and test welders. Written examination, workmanship training, then the performance qualification coupon itself.
6. Stand up the records system. Continuity logs, visual acuity dates, signatures, and a folder structure an examiner can follow without you in the room.
7. Arrange the initial audit. The examiner certifies the welder qualification program as fully functional and properly implemented. Program approval is not a document you write; it is a finding someone else makes.

Where the Money Actually Goes

Nobody can quote you a number without seeing your scope, and anyone who tries should be treated with suspicion. What you can do is understand the drivers so you can price the work yourself.

• Mechanical testing lab fees. Tensile, bend and impact specimens have to be machined and pulled. Per-PQR cost, and it multiplies across material groups and thickness ranges.
• Non-destructive examination. Radiography or ultrasonic examination of coupons before destructive testing, plus any production NDT you owe the contract.
• Engineering time. Someone has to write the WPS, witness the test, and sign the PQR. That is usually your most expensive hourly rate, and it is not billable to the weld.
• Welder time off production. Test coupons consume hours from your best people. In a busy shop this is the hidden cost that hurts most.
• Consultant fees. Reasonable when scoped tightly, ruinous when open-ended.
• Retesting. The one line item that never appears in a budget and always appears in an invoice. Failed bends mean new coupons, new lab fees, new welder time.

Buy the Procedure or Qualify It Yourself?

The AWS-NAVSEA Standard Welding Procedure Specifications for Naval Applications library exists precisely to reduce cost and time compared with qualifying every common procedure independently. You purchase the SWPS-N from the AWS bookstore, and for a large share of routine carbon steel and stainless work you skip the coupon, the lab, and the engineer’s afternoon entirely.

When is buying the wrong call? When your joint detail, thickness, position or material falls outside what the standard procedure covers; when the contract names a revision the purchased document does not match; or when your process mix includes something the library simply does not address, like a specialized copper-nickel piping procedure. In those cases you qualify from scratch, and the TP-248 requirements walk you through it.

The Individual Welder’s Path

If you are a welder rather than a shop owner, the route looks different and takes longer than most people expect. The progression that actually works: solid welding fundamentals first, then code reading so you can interpret a WPS instead of guessing at it, then a formal workmanship course, then coupon practice until restricted-position work is boring rather than stressful, and finally employer-sponsored qualification. A general aluminium welding course or similar trade training builds the hands, but it does not substitute for the employer’s test.

A 90-Day Action Checklist

• Days 1–15: Contract review, invoked document list, revision confirmation with the prime.
• Days 16–35: Gap audit of existing WPS/PQR pairs. Mark each as usable, fixable, or dead.
• Days 36–50: Buy SWPS-N for routine work; scope in-house qualification for the rest. Book the lab.
• Days 51–70: Qualify procedures. Do not test welders against a procedure that is not yet approved.
• Days 71–85: Performance qualification of welders, written exams, visual acuity tests, continuity logs opened.
• Days 86–90: Records review with a fresh pair of eyes, then request the initial audit.

Choosing a Consultant

Good consultants ask to see your contract before quoting. They talk about gap audits and essential variables, not packages. They will tell you which of your existing PQRs are salvageable. Bad ones promise a fixed price to “get you certified” and hand you a binder.

Ask three questions: Have you supported an initial program approval audit before? Can you show a redacted sample of the records system you build? And who signs the PQR — you, or my engineer? If the answer to the last one is vague, keep looking. The signature has to belong to your organization, because the program does too.

One last framing point before the mistakes section. The cost of doing this properly is real but finite. The cost of a rejected procedure at pre-production review is a schedule you cannot recover, because the ship date does not move while you re-qualify. If your program touches aluminium structures, the material-specific pitfalls in our aluminium boat welding guide are worth reading alongside the paperwork, since the process variables and the documentation fail for the same reasons.

Conclusion: Certification Is a System, Not a Card

Go back to the shop from the beginning of this guide. Its welders could run clean beads in their sleep. Its machines were calibrated. What failed at the pre-production review was not craft, it was documentation: no Procedure Qualification Record behind the WPS, no evidence that the welder had been tested to the joint and position in front of them, and no controlled file to prove either. That is the gap NAVSEA welding certification is designed to catch, and it is entirely fixable.

The qualification framework separates two questions that shops often blur together: what must be proven about the method, and what must be proven about the person. Keep those separate in your head and most of the confusion disappears.

The Five Things That Matter Most

• Identify the invoked documents. Read the contract, find the fabrication document, and follow NAVSEA Standard Item 009-12 to the paragraph and material column that applies to your work. Nothing else matters until you know which revision governs.
• Qualify the procedure before the person. A welder cannot be tested against a WPS that has no supporting PQR. Procedure first, always.
• Test to the right variables. Process, position, thickness range, base metal group, filler, and heat input all define the envelope. A welder qualified flat on thin plate is not qualified overhead on thick plate.
• Maintain continuity. Because the maintenance interval is six months, a welder pulled onto fitting work can lose currency faster than a typical annual training cycle. Log qualifying use as it happens, not from memory in December. If position restrictions are part of your envelope, the all position welding rod guide is a useful refresher for your test candidates.
• Keep records audit-ready. Signed, dated, traceable to the WPS and PQR, stored where an examiner can find them in minutes rather than days.

What to Do This Week

1. Pull the contract and list every invoked welding document with its revision letter and any change notices.
2. Inventory existing WPSs and PQRs. Mark each one as current, obsolete, or missing its PQR.
3. Pick your highest-volume production procedure and confirm it is qualified to the invoked revision.
4. Check every welder’s continuity log and last visual acuity date. Flag anyone approaching six months of non-use.
5. Name one person as records owner and back the file up off-site.
6. Book a gap review with your authorized representative or an experienced examiner before work starts, not after the first rejection.

Learnable, Public, and Revision-Driven

The system is learnable. The documents are public, the logic is consistent, and thousands of small shops have built compliant programs without a dedicated quality department. What trips people up is treating requirements as static. Revision letters and change notices alter test requirements, maintenance intervals, and acceptance criteria, and a reprinted PDF floating around a shop floor is not the controlling reference. The contract is. Check NAVSEA and your contract’s revision list before every new job, and date-stamp the copies you work from.

Shops that stay in the marine market tend to build this discipline once and reuse it, much like the practices covered in our AJ Marine welding guide. The paperwork becomes routine, and routine paperwork is what passes audits.

Where This Is Heading

Automation does not remove any of this. Robotic and automatic welding are explicitly within TP-248’s scope, so adding a cell adds qualification work: the procedure, the program, the sensing and tracking variables, and the operator’s performance all need coverage. Expect the documentation burden to grow alongside the equipment, not shrink.

In the end, the card in a welder’s wallet is the least important artifact in the room. The system behind it, the procedure that was proven, the person who was tested to the right variables, and the records that survived review, is the actual asset. Build that, and Navy work stops being a gamble.

Frequently Asked Questions

Is there such a thing as a NAVSEA certification card?

No. NAVSEA does not issue wallet cards or individual certificates to welders. The employing activity qualifies the welder to TP-248 and holds the records, and an examiner certifies that the employer’s program is functioning. What a welder can carry to a new job is documented evidence of past qualification, not a transferable certificate.

How long does a NAVSEA welder qualification last?

It stays valid as long as the welder keeps using the process and the employer maintains the records. TP-248 maintenance rules use a six-month continuity interval, so a welder who stops running a qualified process for longer than that can lose currency and need requalification.

Does an AWS D1.1 certification satisfy NAVSEA requirements?

Generally no. AWS D1.1 is a structural welding code with its own qualification rules, while Navy work is governed by TP-248 and the other documents invoked by the contract. An AWS qualification may support a welder’s background, but the employer still has to qualify to the invoked NAVSEA requirements.

Can a small job shop outside a shipyard get NAVSEA-qualified?

Yes. TP-248 applies to any activity that must meet the requirements when the fabrication document invokes it, and prime contractors routinely flow those requirements down to subcontractors. The shop needs qualified procedures, performance-qualified welders, and a records and quality system that can survive an audit.

What is the difference between TP-248 and MIL-STD-248?

MIL-STD-248 was the older military standard for welding and brazing procedure and performance qualification. It was cancelled in August 1997 and replaced by NAVSEA Technical Publication S9074-AQ-GIB-010/248, which carries the same core qualification logic with updated references and coverage.

Does NAVSEA qualification cover robotic and automatic welding?

Yes, TP-248 explicitly covers manual, semiautomatic, automatic, machine and robotic welding and brazing. Automated processes need their own qualified procedures and, where applicable, qualified operators, so adding a robot creates qualification work rather than bypassing it.

What happens if a welder fails the qualification test?

The employer investigates why before retesting: wrong technique, wrong parameters, poor fit-up, contaminated material, or a procedure that was never capable. A failed test is a data point about the procedure as much as the welder, and repeated failures usually point to a WPS or training problem.

How much does NAVSEA welding qualification cost?

There is no fixed price because the drivers are testing lab fees, nondestructive examination, engineering time, welder time off production, and retesting after failures. Buying an AWS-NAVSEA standard procedure can reduce the cost of qualifying common procedures, but material-specific or unusual work still requires its own qualification effort.
