How Should Vessel Weld Repairs Be Controlled and Closed?

Close one traceable repair package per affected weld and incorporate it in the manufacturing dossier.

DIRECT ANSWERA weld repair begins with a located indication and approved disposition, then controlled removal, re-examination, qualified rewelding, any required heat treatment and final examination. Its history remains linked to the original joint and weld map.

Repair record fields

  • Joint and indication location with original NDE report
  • Defect extent and approved removal method
  • Repair WPS, personnel and cycle count
  • Re-NDE, heat treatment and final acceptance

Relevant manufacturing capability

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

Key notes

  • Grinding an indication away without documented extent and reinspection does not close a repair.

FAQ
