Service 08

A welder certificate proves the welder was competent under test conditions on a particular day. It does not prove that this weld, on this joint, meets the acceptance criteria of your specification. Only inspection does that.

Before the arc is struck

We review the welding procedure specification and its supporting procedure qualification record, verify that welder qualifications are valid and actually cover the joint configuration in production, and confirm consumable control, material traceability, joint preparation and preheat requirements.

Independent of the fabricator

Our inspectors work independently of the shop, so there is no tension between getting the job finished and getting it finished correctly. Non-conformances are raised the day they are found, not batched into a final report when the schedule has already moved on.

Scope of work

  • Visual weld inspection (VT) to ISO 17637 / ISO 5817 acceptance levels
  • WPS and PQR technical review for range of qualification
  • Welder qualification (ISO 9606) validity and continuity checks
  • Fit-up and joint preparation checks before welding
  • Weld gauge measurement: throat, leg, cap height, undercut, misalignment
  • EN 1090 execution class verification and factory production control support
