Fitter​/Welder I

Capitol Engineering is an established and expanding custom fabrication company delivering high quality engineered & fabricated steel products to a wide variety of industries including mining, agriculture, and general industrial applications. Capitol Engineering was established in 1937 and we are currently growing at a rapid pace and are looking to add a Quality Control Assistant to our team.

This position requires an experienced and detail-focused individual that wants to be part of a growing team. The ideal candidate will have a keen eye for detail, strong analytical skills, and a proactive approach to problem solving.

Capitol Engineering is hiring a Welder / Fitter 1 for our Phoenix fabrication shop. This is a hands‑on production role that combines MIG (GMAW) and Flux‑Core (FCAW) welding with material fit‑up and assembly across the full range of custom products we build - structural steel, tanks, ducting, mining and wear equipment, and other specialty fabrications in carbon steel, stainless steel, aluminum, and abrasion‑resistant (AR) plate.

We welcome candidates whose strength is welding, whose strength is fitting, or who do both. Whichever describes you, we want to hear from you - day‑to‑day assignments and skill placement are based on hands‑on ability, and there is a clear path to grow into the other side of the trade over time.

• Perform GMAW (MIG) and FCAW (Flux‑Core) welding on assigned work pieces, in the positions for which you are qualified, in accordance with applicable Welding Procedure Specifications (WPS) and company quality standards.
• Weld on a variety of product types - structural components, tank sections, ducting, equipment frames, wear parts, and other custom fabrications - following work order instructions.
• Set up welding equipment and adjust parameters (wire feed speed, voltage, travel speed, shielding gas) per WPS requirements for each material and joint configuration.
• Perform tack welding to secure components in position prior to final welding sequences.

• Position and secure components for structural assemblies, tank sections, equipment frames, ducting, and other custom fabrications in accordance with work orders and shop sketches.
• Use measuring and layout tools - tape measure, combination square, torpedo level, framing square, soapstone - to verify component dimensions, squareness, and alignment before tacking.
• Prep weld joints using grinders, wire wheels, and flap discs, applying the correct tooling and contamination‑prevention practices for the material being prepared.
• Report fit‑up discrepancies or missing information to the Shop Lead before proceeding.

• Verify joint cleanliness, fit‑up condition, and WPS parameters before beginning each weld assignment.
• Perform visual self‑inspection of completed welds against acceptance criteria - size, length, profile, fusion, porosity, undercut, and overlap - before releasing work.
• Report weld defects, non‑conformances, or quality concerns to the Shop Lead immediately.

• Operate welding equipment, wire feeders, power sources, cutting tools, and associated tooling proficiently and safely; perform pre‑use checks each shift and report issues promptly.
• Wear all required PPE at all times and follow facility safety protocols, lockout/tagout procedures, fume extraction requirements, and material‑specific handling and ventilation practices.
• Maintain a clean, organized, and safe work station throughout the shift and report unsafe conditions or near‑misses to supervision immediately.
• Perform other related duties as assigned in support of production operations.

• High school diploma or equivalent.
• 3-5 years of production welding and/or fabrication experience across multiple product types.
• Strength in one or both sides of the role: an active welder performance qualification using GMAW (MIG) per applicable welding code or company WPS, and/or demonstrated fit‑up and assembly ability using measuring and layout tools.
• Ability to read and follow work orders, shop sketches, and WPS documentation, and…
