Orbital Welder III – Precision Fabrication

About the role

Applied Materials is seeking an experienced Orbital Welder III to join its precision‑fabrication team. You will operate orbital welding equipment to build, repair, and test mechanical, vacuum, and pneumatic assemblies used in semiconductor manufacturing equipment. The role requires strict attention to weld quality, cleanliness, and repeatability in a cleanroom‑adjacent environment.

Key responsibilities

• Set up and operate autogenous and wire‑fed orbital welding equipment to join stainless steel and specialty alloy tubing to exacting standards.
• Read and interpret work orders, blueprints, weld procedure specifications (WPS), and P&ID drawings to determine weld sequence and acceptance criteria.
• Perform mechanical assembly, disassembly, troubleshooting, and repair of vacuum, gas‑delivery, and pneumatic sub‑assemblies.
• Inspect welds visually and with precision measuring and leak‑detection instruments; document and correct defects.
• Maintain accurate records of labor, material usage, and progress in the production tracking system.
• Calibrate, maintain, and troubleshoot orbital welding heads and power supplies; report equipment issues.

Required profile

• High school diploma or GED; technical diploma or associate degree in welding technology or related trade preferred.
• 3‑5 years of hands‑on welding experience in manufacturing, aerospace, semiconductor, or high‑purity environments; orbital/TIG experience a plus.
• Current or attainable welder certification such as AWS D1.1/D1.6 or ASME Section IX.
• Ability to obtain or maintain OSHA 10 training.

Required skills

• Orbital GTAW/TIG welding of stainless‑steel tubing (typically 1/8" to 1/2" O.D.).
• Manual TIG and MIG welding proficiency.
• Reading and applying AWS welding symbols, WPS, and engineering drawings/blueprints.
• Use of leak detectors, vacuum pumps, and precision measuring equipment.
• Knowledge of high‑purity semiconductor cleanliness standards (e.g., SEMI F19/F20).
• Basic computer literacy for data entry into MES/ERP systems.

What we offer

• Salary range $23.00 – $31.40 per hour.
• Comprehensive benefits package including medical, dental, vision, 401(k) match, employee stock purchase plan, paid time off, and eligibility for bonus and stock awards.
• Supportive work culture with opportunities for learning, development, and career growth.
