What documents go in a WPS submittal package to the engineer of record?

The package should include the WPS form (AWS Annex M format or equivalent), the supporting PQR(s), all applicable PQR test reports (tensile, bend, CVN if required), the welder's WPQ records for the relevant process, and identification of the governing code edition. Some EORs also request the filler metal certifications.

How early should a fabricator submit WPS packages to the EOR?

Target at least 4–6 weeks before production welding begins. EOR review can take 2–4 weeks, and any rejection requiring a new PQR adds coupon fabrication and lab testing time — typically 2–3 weeks minimum.

What are the most common reasons an EOR rejects a WPS submittal?

Missing PQR test reports, essential variable ranges that do not cover the production joint (wrong thickness or position), wrong code edition cited, mismatched base metal classification, and expired welder qualifications on the WPQ.

Can a fabricator use an ASME IX PQR to support an AWS D1.1 WPS?

Generally no. AWS D1.1 and ASME IX have different essential variables and different test specimen requirements. Unless the EOR and applicable code explicitly permit equivalency, a D1.1 WPS must be supported by a D1.1-compliant PQR.

WPS Submittal Package for EOR Review: Checklist

What engineers of record need when reviewing a fab shop's WPS submittal — AWS D1.1:2025 compliance, PQR test reports, and the most common rejection triggers.

Why the WPS Submittal Matters

A Welding Procedure Specification is a shop's internal document — but on most structural projects governed by AWS D1.1, the engineer of record (EOR) or owner's inspector has the right, and often the contractual obligation, to review and approve the WPS and its supporting Procedure Qualification Record before production welding starts. The submittal package is how that review happens.

A well-organized, complete submittal moves through EOR review in days. A disorganized or incomplete one bounces back, burns project schedule, and, on tight programs, ends up on the fast track to a variance or a waiver that nobody wanted. Understanding what goes into a technically complete submittal — and the half-dozen issues that trigger most rejections — protects the fabricator's schedule and the EOR's review time.

Document Checklist: What Goes in the Package

1. The WPS Form

The WPS itself should use AWS Annex M format or a format that captures all Annex M fields. If your shop uses a custom form, every mandatory WPS element from AWS D1.1:2025 must be present: welding process(es), base metal P-number or group classification, filler metal classification and F-number, current type and polarity, position(s), preheat and interpass temperature, shielding gas (if applicable), and the qualified ranges for all essential variables.

The WPS must cite the governing code edition — AWS D1.1:2025, or whichever edition the project specification requires. Submitting a D1.1:2020 WPS on a contract that specifies D1.1:2025 (or vice versa) is a rejection trigger, even if the WPS is otherwise technically correct.

2. The Supporting PQR(s)

Each WPS must be supported by one or more PQRs that document the actual test conditions. The PQR form should include all welding variables as actually used during the test, the test position and joint geometry, the preheat temperature applied, and the essential variable values that establish the ranges covered by the WPS.

Attach the PQR form signed by a responsible welding engineer or CWI, not just a summary. Some fabricators submit only a one-page WPS and forget the PQR entirely; this is the single most common rejection cause.

3. Test Reports

The PQR records the variables. The test reports prove the mechanical properties. A complete PQR package includes:

Tensile test reports — all-weld-metal and/or reduced-section tensile, depending on joint type. For groove welds, the tensile specimen is reduced-section across the weld. Acceptance: tensile strength ≥ base metal classification UTS per AWS D1.1 Table 4.5.
Bend test reports — face bend and root bend (or side bends for plate ≥3/8 in [10 mm]). Acceptance: no open defect exceeding 1/8 in [3 mm] in any direction.
CVN impact test reports (if required by the project specification or contract). CVN supplementary essential variables are governed by AWS D1.1:2025 Table 6.8. If CVN testing was required for the PQR, include the full charpy test report with specimen size, test temperature, and individual and average energy values.
Macro-etch sections for fillet weld procedures if required by the project specification.

All test reports should be from an independent, accredited laboratory with A2LA or equivalent certification. Some EORs specifically require this; others take shop-run tests if witnessed by an independent CWI.

4. Welder Performance Qualification Records (WPQs)

WPQ records confirm that the welders assigned to the work are qualified for the process, position, and joint type in the WPS. Submit WPQs for each welder (or welder category, if the contract permits grouping) that will work on the qualifying scope.

Verify that the WPQs have not lapsed. AWS D1.1 Clause 6.4.1 requires that a welder maintain continuity — documented use of the process — within each 6-month period. A gap greater than six months requires requalification. See AWS D1.1 welder continuity and the six-month rule for how to track and document continuity for your roster.

5. Filler Metal Certifications

Some EORs request certified mill test reports (CMTRs) or manufacturer's certifications for the filler metals cited in the WPS. This is more common on bridge or infrastructure projects governed by AWS D1.5, but is also requested on AISC-certified fab work and owner-specified programs. Include them if the specification or EOR RFI list asks for them.

For more on how filler metal classification ties into essential variables and WPS scope, see welding consumable certifications and traceability.

The Eight Most Common Rejection Triggers

1. Essential variable ranges do not cover the production joint. The WPS qualified on 3/4 in plate does not cover a 2 in groove weld. The WPS qualified in the flat position does not cover a vertical butt joint. Check thickness and position ranges before submitting — these are the two most frequent coverage mismatches.

2. Missing PQR or test reports. Submitting the WPS form alone without the PQR, or the PQR form without the lab test reports, is not a complete submittal. Some EORs will bounce it as a non-responsive submission, resetting the review clock.

3. Wrong code edition. A project specification that says "per AWS D1.1:2025" cannot be supported by a WPS that cites AWS D1.1:2020, even if the substantive content is identical. The edition governs which table numbering and which essential variables apply. If your WPS was qualified under 2020 and the contract requires 2025, confirm with the EOR whether your existing PQR is acceptable under the 2025 edition's rules.

4. Expired welder qualifications. A WPQ that shows the welder's last qualification test was 18 months ago with no continuity documentation since is disqualifying. Maintain a continuity log for every welder and submit it with the WPQ.

5. Mismatched base metal classification. An A36 WPS does not automatically cover A992 wide flange — both are AWS D1.1 Group I base metals, but if the PQR coupon was A36 and your production material is A992, verify the WPS explicitly lists A992 or confirms Group I coverage.

6. Unsigned or undated documents. WPS and PQR forms should be signed and dated by a responsible individual — typically the welding engineer, CWI, or QC manager. Unsigned documents carry no QA standing.

7. Transfer mode or process variant not documented. If the WPS covers GMAW, it must state the transfer mode. A WPS that says only "GMAW" without specifying spray, short-circuit, or pulse creates ambiguity — and sophisticated EOR reviewers will flag it. See GMAW transfer mode as an essential variable for why this matters.

8. No disclaimer for code edition on rule values. If the WPS or cover letter references specific table values from D1.1, note which edition those values come from. This protects both parties when a governing edition dispute arises later.

Rule library based on AWS D1.1:2025; verify against your governing edition — the AHJ or contract may specify 2020 or earlier.

Timing and Submittal Protocol

The practical minimum lead time for WPS submittal is 4–6 weeks before production welding. Budget an additional 2–3 weeks if any part of the package is rejected and you need to run a new PQR: coupon prep (1 week), welding and cooling, lab delivery and testing (5–10 business days), and report return.

Organize the submittal as a single PDF package — one file per WPS, with its PQR(s) and test reports appended. Include a cover sheet with the project name, contract number, applicable code edition, and your QC contact. Some EORs use a transmittal log; match their format if one is specified.

Keep a copy of every submitted and stamped package in your document control system. In an AISC audit or an owner's inspection, the submittal record proves that procedures were reviewed and approved before production — not after a problem was found.
