How Are Pressure-Vessel Welded Joints Inspected?

Tie every inspected joint to the weld map, procedure and signed result.

DIRECT ANSWERWelded joints are controlled through in-process checks, visual and dimensional examination, and the RT, UT, MT, PT or other methods required by approved documents.

Joint inspection plan

  • Joint category, material and thickness
  • Fit-up, welding parameters and visual criteria
  • NDE method, coverage, timing and acceptance
  • Repair, re-examination and record closeout

Relevant manufacturing capability

  • Manufacturing-stage quality planning
  • Multi-method inspection and test coordination
  • Traceable release and manufacturing-dossier records

Key notes

  • A percentage without method, location and acceptance criteria is ambiguous.
