Overview
The Process Piping Welding Inspector supports semiconductor tool installation projects by ensuring all high-purity process piping systems meet stringent quality, cleanliness, and compliance requirements. This role is critical to maintaining the integrity of ultra-high purity (UHP) gas and chemical delivery systems used in advanced semiconductor manufacturing.
Responsibilities
- Inspect orbital and manual welds on stainless steel tubing used in UHP gas and chemical distribution systems.
- Inspect synthetic pipe systems bonded together.
- Ensure compliance with project specifications, SEMI standards, and ASME B31.3 requirements.
- Review and verify Welding Procedure Specifications (WPS), Procedure Qualification Records (PQR), Bonding Procedure Specification (BPS) and manual welder & orbital operator certifications.
- Monitor purge gas quality, oxygen levels, and welding parameters to meet semiconductor-grade standards.
- Perform and/or witness visual inspections and borescope examinations of internal weld surfaces.
- Verify material traceability, including heat numbers, MTRs, and tubing certifications (electropolished systems).
- Ensure strict adherence to cleanliness protocols, including particle control and contamination prevention.
- Coordinate other non-destructive testing (NDT) activities where required.
- Identify, document, and track product non-conformances; ensure corrective actions are properly implemented.
- Compile and review turnover packages, including weld logs, inspection reports, and quality documentation.
- Collaborate with tool install teams, engineers, owners QA/QC personnel, to maintain schedule and quality targets.
- Enforce safety and cleanroom compliance at all times.
Requirements
- High school diploma or equivalent; technical degree or trade certification preferred.
- AWS Certified Welding Inspector (CWI Level 2) required.
- 6+ years of welding inspection experience, with at least 2–3 years in semiconductor or UHP piping environments.
- Strong expertise in orbital GTAW (TIG) welding for stainless steel tubing.
- Working knowledge of SEMI standards and high-purity piping practices.
- Experience with semiconductor systems such as gas panels, valve manifold boxes (VMBs), bulk gas and tool hook-ups.
- Ability to read and interpret Isometric drawings ISO’s, P&ID’s, ITP’s and ITR’s.
- Familiarity with oxygen/moisture analysis requirements and purge verification.
- Previous experience on the welding of Piping, Thin wall tubing, Bonding of synthetic lines and pipe support installation.
- Experience with electropolished (EP) tubing, passivation, and high-purity installation techniques.
- Additional certifications (e.g., API 570, VT Level II).
- Strong QA/QC documentation and turnover package experience.
Benefits
- Health Insurance
- Dental

Additional Information
- Work performed in semiconductor fabrication facilities (cleanroom environments).
- Strict gowning, contamination control, and protocol adherence required.
- May involve extended hours, shift work.
- Physically demanding: prolonged standing, working in confined spaces, climbing ladders, climbing access scaffolds, working from AWP’s or scissor lifts.
