Requirements
- Hold a current AWS Certified Welding Inspector (CWI) credential and have signed off on structural or pressure welds to AWS D1.1 or an equivalent code.
- Written and qualified WPS and PQR documentation for production welding.
- Stood up or run a weld quality program in a manufacturing or fabrication environment producing at rate.
- Qualified welders and managed the continuity records that keep a line's certifications valid.
- Root-caused weld defects on the floor and closed the loop by fixing the procedure, the fixture, or the training, so the same defect doesn't come back.

Responsibilities

- Build the weld quality program for a factory producing data center modules at rate, setting the acceptance criteria, NDE requirements, and first-pass-yield targets.
- Qualify welders and welding operators, and stand up the continuity and requalification tracking that keeps the whole line certified.
