Description
The Semiconductor TIG Welder performs high-purity autogenous GTAW/TIG fusion welding on plain-end stainless-steel process piping for semiconductor tool installation. The role requires preparing, aligning, purging, and inspecting welds without filler wire, grinding, or unauthorized cosmetic repair, while maintaining cleanroom cleanliness and meeting strict material-condition and quality standards. The welder must independently demonstrate material handling, cutting and facing, fit-up, alignment, equipment setup, fusion welding, and defect recognition, and follow semiconductor safety, quality, and documentation requirements.
