Weld Documentation and Compliance for Metal Fabrication Shops

The Record Chain an Auditor Follows

A customer or third-party auditor typically traces a weld back through several documents. The drawing calls out the weld symbol and code. The job references a WPS covering base metal, filler, process, position and parameter ranges.

The WPS rests on a PQR, which is the test record that proved the procedure. Each welder or operator who welded the job needs a qualification record, such as a WPQ, valid for the process and position, with continuity requirements that lapse if the welder has not used the process within the allowed interval. Inspection records, including visual by a certified weld inspector (CWI) and any NDT, close the loop.

What Typically Goes Wrong

Gaps are rarely about welding quality and usually about paperwork and timing. A welder's qualification expired and nobody noticed. A WPS was revised but the old one is still posted on the floor.

A job was welded with a different filler lot than the one documented. Heat numbers for structural members are not tied to the job. The CWI signs a batch after the fact.

Each of these is a finding in a customer audit and a rework risk if the customer rejects the lot. The fix is not more binders, but a system that connects the job, the procedure, the welder and the material, with alerts on upcoming expirations.

• Welder qualification continuity and expiration dates
• WPS revision control and the version in use at each station
• Filler metal and shielding gas lot traceability
• Mill test reports linked to heat numbers on the job
• Inspection sign-off timing and CWI certification currency

Where the ERP and Quality System Fit

Your ERP can hold the job routing, material lots and operator labor records. A quality system, or a quality module in SyteLine, Epicor, Plex or similar, can carry inspection plans, nonconformance reports and certificates. What typically needs custom attention is the welder-to-job link: recording who welded which job, against which WPS, and whether their qualification covered that process and position on that date.

Some shops add a simple tracking table or form to the weld operation. Others rely on a weld log. The goal is a record you can produce in minutes, not a folder search that takes a day during an audit.

Certifications Beyond Welding Codes

Many fabricators also carry ISO 9001, and aerospace or defense suppliers may hold AS9100 and, where applicable, NADCAP accreditation for welding. Defense work can add DFARS specialty metals requirements, domestic content rules such as Buy American for federally funded projects, and cybersecurity obligations under CMMC for controlled drawings. These add document control and traceability demands on top of the weld records.

Keep the claims you make to customers accurate: your certificate scope should match the processes you actually perform, and any special process approvals should be current.

Using AI on Compliance Records

AI can help find the needle in the haystack: given a job number, assemble the drawing, WPS, welder qualifications, material certs and inspection records into one packet and flag what is missing or expired. It can also scan your records weekly for qualifications nearing expiry. It should not decide that a weld is acceptable or sign anything.

If your volume is small and your binder is well kept, a spreadsheet with expiration reminders may be all you need. Where audits are frequent and records are scattered, a private document search over your own files saves real time.
