Welded assemblies

Check welded assemblies, appraise them in the event of failure and qualify procedures.

Objectives

  • Advise and participate in the development and validation of specifications
  • Assist in the finalisation process (feedback, failure analysis and fatigue)
  • Develop welding records
  • Qualify welding procedures
  • Verify compliance of assemblies (acceptance record)
  • Appraise and analyze failures
  • Qualify finishing processes of welding beads
  • Ensure the development of finishing methods
