Welding Inspection
CSWIP/IWI-level visual and procedural weld inspection, WPS/PQR review and welder qualification oversight — confirming that welded fabrication conforms to ISO 3834 and EN 1090 before it's accepted into a structure or pressure system.
Welding defects that pass unnoticed at fabrication stage are expensive and sometimes dangerous to find later. Our inspectors work independently of the fabricator, so there's no conflict of interest between getting the job finished and getting it finished correctly — non-conformances are raised the day they're found, not batched into a final report.
We inspect against the execution class and fabrication standard specified in your contract, whether that's a structural steel frame under EN 1090 or a pressure component under a client-specific procedure.
Our capabilities.
The specific activities this service covers — scoped to your contract, insurer or regulator's requirements.
- Visual weld inspection (VT) to ISO 5817 / ISO 17635 acceptance criteria
- Welding Procedure Specification (WPS) and Procedure Qualification Record (PQR) review
- Welder Qualification Test (WQT) witnessing
- Hold-point and staged inspection throughout fabrication
- Fit-up and joint preparation checks prior to welding
- Execution class verification per EN 1090-2
What you get that a generic checklist doesn't.
- CSWIP / IWI-qualified inspectors
- Inspection scoped to the exact execution class and fabrication standard in the contract
- Fully independent of the fabricator — no conflict of interest
- Non-conformance reports issued same-day, not held for a final report
