Why Are Weld Maps Important for Vessel Traceability?

Reconcile the final map against the as-built drawing and dossier index before release.

DIRECT ANSWERA weld map gives every pressure-boundary joint a stable identity so material heats, welders, WPSs, consumables, NDE, repairs and heat-treatment records can be traced to the built vessel. It must follow approved drawing revisions and actual shop joints.

Weld-map release checks

  • Joint number and drawing location
  • Material and part identities either side of the joint
  • WPS, welder and production date
  • NDE, repair and PWHT record references

Relevant manufacturing capability

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

Key notes

  • A neat drawing without record links is not a traceability map.

01What happens when a field joint is added?

Give it a controlled new identity and update the drawing, WPS coverage, inspection plan and final records.
