The “Week Before the Audit” Panic
It’s a familiar scene in fabrication shops worldwide: The ISO 3834 or EN 1090 audit is scheduled for next Tuesday. The Welding Coordinator is frantically hunting for a PQR from three years ago, the HR manager is trying to update welder continuity logs in Excel, and nobody is quite sure if the calibration certificates for the welding machines are current.
This “scramble” happens because quality records are often treated as archives rather than living data. But auditors aren’t just checking boxes; they are looking for a system.
What ISO 3834 and EN 1090 Actually Expect
At their core, these standards require traceability and control. They want proof that:
- You planned the weld (WPS) based on a qualified test (WPQR/PQR).
- The person welding it was qualified (Welder Cert) and their skills are current (Continuity).
- The actual welding parameters matched the plan.
- Inspection was performed and recorded.
Check out our guide on Digital Welding Traceability for a deeper dive into the requirements. For weld acceptance criteria that your procedures and ITPs must reference, see our guide on ISO 5817 quality levels B, C, D — acceptance criteria. When audit findings surface nonconformances, use a structured welding CAPA root cause and 8D workflow to close them faster.
Audit Hotspots: Where Manufacturers Typically Fail
Based on our experience with hundreds of fabricators, here is where the non-conformances (NCRs) usually hide:
- Welder Continuity Gaps: “I know he welded last month, but we didn’t write it down.” Without a log (signed every 6 months), the qualification expires.
- WPS Availability: The WPS is in the office folder, not at the welder’s station.
- Material Traceability: Can you link the filler wire batch number to the specific project?
- Repair Records: Repairs often happen “off the books.” Auditors look for a documented repair procedure and re-inspection record.

Request TemplateFrom Paper to Digital: Making the Checklist “Self-Maintaining”
The hardest part of this checklist is the manual upkeep. In a modern QMS, many of these boxes are checked automatically:
- Auto-Continuity: Smart welding machines record arc time against a welder’s ID, automatically updating their continuity log.
- Digital WPS: The correct WPS parameters are sent directly to the machine or displayed on a screen, ensuring revision control.
- Traceability: Real-time monitoring links the specific weld data (volts, amps, thermal profile) to the serial number instantly. A fixed thermal weld camera feeds this thermal profile straight into the weld record.
Instead of hunting for paper, you open a dashboard and show the auditor the live “Green Status” of your production.

Frequently Asked Questions
What do ISO 3834 and EN 1090 require from a welding manufacturer?
Both standards require traceability and control: proof that each weld was planned via a qualified WPS backed by a PQR, the welder was certified and kept current on continuity logs, actual welding parameters matched the approved plan, and inspection was performed and recorded.
Where do ISO 3834 and EN 1090 audits most often find non-conformances?
Common audit hotspots include welder continuity gaps (missing 6-month confirmation logs), WPS availability failures (procedures stored in the office rather than at the welder's station), material traceability gaps (inability to link filler wire batch to a specific project), and undocumented repair records.
What qualifications must a Responsible Welding Coordinator have under ISO 3834?
The Responsible Welding Coordinator (RWC) must be formally appointed with welding responsibilities defined in the org chart, and must hold an IWE (International Welding Engineer), IWT (International Welding Technologist), or IWS (International Welding Specialist) qualification.
