Can a welder bring their WPQ from one fab shop to another under AWS D1.1?

Yes, with conditions. AWS D1.1 Clause 6.4 allows a new employer to accept a welder's existing qualification record, but the new employer must obtain the original test records and verify the welder has maintained continuity — no lapse of more than six months from the process qualified. The new employer becomes responsible for the WPQ from that point forward.

Does a welder have to retest when changing employers under AWS D1.1?

Not necessarily. If the new employer can obtain the original WPQ test records, verify continuity, and confirm the welder's prior tests cover the positions and processes needed, requalification can be waived. However, the new employer can always require a retest as a matter of shop policy — some owners and project specifications require fresh testing for each new engagement.

What happens if the welder's prior employer no longer has the records?

Missing records are a disqualifier. Without documentation of the original test — test positions, base metal group, process, filler metal classification, and pass/fail results — the employer cannot satisfy AWS D1.1 Clause 6.4's record-keeping requirements. The welder must requalify. This is one of the most common WPQ compliance gaps found during audits.

How long does AWS D1.1 continuity last, and what breaks it?

AWS D1.1 Clause 6.4.1 requires a welder to have used each qualified process within a rolling six-month window. A lapse longer than six months in a specific process breaks continuity for that process, requiring requalification by test. Continuity for other processes the welder has actively used remains intact.

Welder WPQ Portability Between Fab Shops: AWS D1.1 Rules

AWS D1.1 lets a welder carry their WPQ to a new employer — but only under specific conditions. Here's what transfers, what doesn't, and what the new shop must do.

When a skilled welder walks through your shop door with a thick folder of prior qualifications, the natural instinct is to accept them and put that person on the floor. AWS D1.1 does allow qualification records to follow a welder from one employer to another — but the standard places the burden of verification squarely on the new employer. Getting this wrong exposes your firm to failed audits, rejected weld records, and potential liability on the structure.

What the Standard Actually Says

AWS D1.1:2025 Clause 6.4 establishes the qualification requirements for welders and welding operators. The standard does not prohibit transferring WPQs between employers, but it contains no blanket automatic acceptance clause either. The requirement is record-based: the new employer must possess the actual test documentation — not a summary or verbal assurance — that the qualification was earned under conditions the standard recognizes.

The key items the prior test record must establish:

Welding process(es) qualified (SMAW, FCAW-G, GMAW, GTAW, SAW, etc.)
Test position(s) — 1G, 2G, 3G, 4G, 6G, and applicable fillet qualifications
Base metal group (Per AWS D1.1, structural base metals are grouped; the test record should identify the material or the applicable base metal category)
Filler metal classification used during the test
Test results — bend test, visual, and any required tensile or macro results
Date of the test — essential for evaluating continuity
Identity of the testing supervisor or CWI who witnessed the qualification test

If any of these elements are missing or cannot be reconstructed from supplementary records, the record is incomplete and the prior qualification cannot be relied upon.

Continuity: The Six-Month Rule in Practice

Even a perfect set of test records is worth nothing if the welder has not maintained continuity. AWS D1.1 Clause 6.4.1 is explicit: a welder who has not used a qualified process for a period exceeding six months must requalify for that process by test.

Continuity is process-specific, not credential-wide. A welder qualified for SMAW and FCAW-G who has been running SMAW continuously but has not touched a FCAW gun in eight months is still qualified for SMAW but has lost FCAW-G continuity — even though they never stopped welding.

This matters enormously when onboarding a new welder:

Get the test records and determine what processes are documented.
Verify the date of the most recent test or documented production use of each process.
For each process, calculate whether a continuous six-month window can be established through the date the welder joins your shop.

The new employer must be able to draw an unbroken line. If the prior employer can provide production records, welder time cards, or weld logs showing the welder was actively making production welds with a given process each month, that can satisfy continuity even when the original test is older than six months. The test establishes capability; documented production use maintains it.

What Transfers and What Does Not

Transfers cleanly:

Documented test positions and processes
Fillet weld qualifications derived from groove weld qualification (per the applicable position substitution rules in Clause 6.3)
Continuity, if records support it

Does not automatically transfer:

Project-specific or owner-specific additional requirements. Some project specifications or owner QC plans require fresh qualification testing at the start of each engagement regardless of prior records. Bridge work under AWS D1.5, for example, often carries additional testing requirements.
Qualifications earned under ASME IX or API 1104 do not substitute for AWS D1.1 WPQ tests. These are different standards with different test requirements. A welder qualified under ASME IX must requalify under AWS D1.1 if the work is governed by AWS D1.1.
Welding operator qualification records (for mechanized/automated processes) have their own transfer conditions and are sometimes handled differently by project specifications.

What the New Shop Must Do

The new employer is responsible for the WPQ from the moment they accept the welder into production. Here's the checklist:

Step 1 — Collect original records. Contact the prior employer and request copies of the WPQ test records. Photocopies and PDFs are generally acceptable. Note that some employers treat these records as confidential, which can complicate transfer; have the welder request their own records if direct employer-to-employer communication stalls.

Step 2 — Verify continuity. Request production weld logs, time cards, or any contemporaneous documentation showing the welder has used each process without a six-month gap up to their last day of employment. Gap in records = presumed lapse.

Step 3 — Confirm scope matches project needs. Check the positions and processes you need against the record. If a welder is qualified 1G and 2G but your structural connection work requires vertical and overhead positions, the prior record does not cover those — requalification in 3G or 4G is required regardless of how experienced the welder is.

Step 4 — Document acceptance. Create an internal record (a form in your WPQ file or your digital WPS software) that records: date of employment start, prior employer name, test record references received, continuity verification, and the conclusion that the record was accepted or that a new test was performed. This documentation is what an auditor will look at.

Step 5 — Track continuity from here forward. The new employer now owns the continuity clock. The welder's six-month window restarts from when they begin using each process at the new shop. If your shop uses welder continuity tracking software, automated alerts can catch an impending lapse before it becomes a compliance gap.

Common Audit Findings

Third-party auditors and special inspectors under IBC Chapter 17 frequently cite welder qualification records as a primary deficiency category. The most common WPQ portability failures:

No original test records — the shop accepted a welder's verbal representation or a laminated card without the underlying test documentation.
Continuity gap not evaluated — the prior test date was noted but no one asked what the welder was doing between then and their hire date.
Scope mismatch — the prior record qualifies one process but the shop is using the welder on a different process without additional testing.
Records from a different standard — ASME IX or AWS D1.5 qualifications accepted in lieu of AWS D1.1 tests.

When Requalification Is the Cleaner Answer

Sometimes it makes more practical sense to simply retest a new welder rather than trace their history through a prior employer's filing system. The test itself — typically a groove weld coupon in the required position, followed by bend tests — takes a few hours. If the prior records are fragmentary, if continuity documentation is thin, or if the project owner requires fresh testing, a new qualification eliminates the uncertainty entirely.

For shops running digital WPS and WPQ management, building a new qualification record is straightforward. See how WPS and WPQ records integrate in audit-ready qualification libraries and the WPQ traceability documentation requirements for how to structure those records from day one.
