For fabricators aiming to certify to ISO 3834-2, the key elements include:
• Review of contracts and design requirements before fabrication begins.
• Qualification of welding procedures (WPQR) and welders (WQT) to relevant product standards.
• Control of production welding, including consumable storage, preheat, and interpass temperatures.
• Non-destructive testing and final inspection with clear acceptance criteria.
• Documentation and traceability of all quality records.
Many fabricators underestimate the documentation burden. A gap in weld maps or missing NDT reports can lead to non-conformances. The standard also requires calibration of measuring and test equipment, which is often overlooked.
How does your organization manage the transition between ISO 3834-3 and 3834-2 when project requirements escalate?
