We are seeking an experienced Quality Welding Engineer to support fabrication of ultra‑high‑purity (UHP) gas delivery systems for semiconductor process equipment, including gas panel assemblies and chamber weldments. This role owns weld quality across the fabrication lifecycle — procedure qualification, welder certification, in‑process inspection, and nonconformance resolution — within a controlled cleanroom manufacturing environment. The ideal candidate combines deep orbital welding and stainless steel metallurgy expertise with fluency in the SEMI standards that govern UHP gas system integrity.

• Develop, qualify, and maintain welding procedure specifications (WPS) and procedure qualification records (PQR) for orbital GTAW of UHP gas lines, gas panels, and chamber weldments.
• Establish and audit welder/operator qualification programs for orbital and manual welding personnel working on UHP systems.
• Serve as the site subject matter expert on applicable SEMI standards, including F78 (particle contamination / cleanroom compatibility), F81 (surface roughness for UHP components), E49.8 (orbital weld documentation and acceptance), F70 (UHP gas distribution system components), and related SEMI specifications governing gas delivery hardware.
• Own weld quality within cleanroom fabrication cells: gowning discipline, purge gas control, /OD surface finish verification, and contamination prevention throughout the weld process.
• Perform and oversee visual, boroscopic, and dimensional weld inspection against acceptance criteria; drive root‑cause analysis and corrective action for weld discrepancies and nonconformances.
• Provide metallurgical oversight of 316L stainless steel (and related UHP alloys) including heat‑affected‑zone control, oxide/heat‑tint discoloration limits, interpass temperature, and purge gas (Ar/back‑purge) requirements to preserve corrosion resistance and surface passivation.
• Specify, evaluate, and maintain orbital welding equipment — power supplies, weld heads, and tube‑prep tooling — from manufacturers such as Arc Machines Inc. (AMI), Polysoude, Orbitalum, and equivalent, including PQ/programming, preventive maintenance, and end‑of‑life qualification.
