You should request documentation related to the fabrication and welding as well as testing, inspection, and repair of the finished components for the following items:

  • Manufacturing Procedure Specification (MPS)
  • Quality Plan (including the Inspection and Test Plan)
  • WPS, PQR, and welder qualifications
  • NDE procedures, records, and qualifications of NDE personnel
  • Non-conformance/discrepancy reports and final dispositions
  • Weld Consumable Certificate of Compliance
  • Weld repair maps
  • Weld summary sheet identifying all WPS and processes, and the locations where the WPS should be used
  • Dimensional reports
  • Classification Certificate (if required)
  • Heat treatment records (if applicable)
