Production Approach

Automation where it matters. Experience everywhere else.

Automated processing improves repeatability, while experienced fitters, welders, inspectors, and project teams manage the conditions that require judgment.

  • Material identification and traceability
  • Controlled fit-up and welding procedures
  • In-process and final inspection
  • Sequenced shipping and documentation
