Heavy Steel Duct Welder

Heavy Steel Duct Welder
Phoenix, AZ 85041

About the Role

This is a hands-on production welding and fit-up role focused on fabricating heavy-gauge industrial ductwork and related components (round and rectangular duct, elbows, transitions, hoppers, chutes, and specialty fabrications). You will perform all-position TIG (GTAW) and Flux-Core (FCAW) welding, including large-diameter work up to 10' diameter, Client out and fit-up from drawings, and produce high-quality work on thicker plate typical of industrial/mining applications (not light-gauge HVAC sheet metal).

What You'll Do

Production Welding

• Perform GTAW (TIG) and FCAW (Flux-Core) welding in all positions (1F–4F, 1G–4G) on heavy steel ductwork, transitions, elbows, hoppers, and related industrial fabrications.
• Weld large-diameter duct and components up to 10' diameter.
• Execute multi-pass welds on carbon steel, stainless steel, aluminum, and AR plate per company WPS and applicable acceptance criteria.
• Select and verify correct filler metals, shielding gases, and parameters for each material and joint configuration (including proper practices for stainless and aluminum).
• Consistently produce welds that meet drawing and quality requirements with minimal supervision.

Fit-Up, Layout & Assembly

• Independently Client out, fit, and assemble duct sections and custom components from fabrication drawings using tape measures, squares, levels, and other layout tools.
• Perform accurate tack welding and weld sequencing on varied geometries and thicknesses.
• Prepare joints with grinders, wire wheels, and flap discs (including contamination-prevention practices for stainless).
• Identify and report fit-up, dimensional, or drawing issues to the Shop Lead before proceeding.

Quality, Safety & Team Support

• Self-inspect completed welds and assemblies against drawings and acceptance criteria.
• Operate welding equipment, grinders, and related tools safely; perform pre-use checks and report issues.
• Maintain a clean, organized work area and follow all PPE, lockout/tagout, fume extraction, and shop safety protocols.
• Provide informal guidance to less-experienced welders or apprentices as needed.
• Perform other related duties as assigned.

What We're Looking For

Required

• High school diploma or equivalent.
• Minimum of 3 years of production welding and/or heavy fabrication experience, preferably including industrial ductwork, platework, tanks, hoppers, or structural components.
• Active welder performance qualifications in all positions using GTAW (TIG) and FCAW (Flux-Core), documented and current per applicable WPS or code.
• Demonstrated ability to perform independent structural/custom fit-up and layout from drawings.
• Strong ability to read and interpret fabrication drawings, weld symbols, dimensions, and tolerances.
• Proficiency with angle grinders and hand tools for preparation and finishing across multiple materials.
• Reliable attendance, strong work ethic, and commitment to quality and safety.
