Fitter​/Welder II

About this position

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 2 for our Phoenix fabrication shop. This is a mid-level production role that pairs strong all-position MIG (GMAW) and Flux-Core (FCAW) welding with the ability to lay out and fit up assemblies independently from drawings - across the full range of custom products we build, including 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. At this level we expect confident capability on at least one side and working proficiency across both - handling assignments of increasing complexity with minimal supervision, reading fabrication drawings and weld symbols, and helping bring less-experienced shop staff up to speed.

• Perform GMAW (MIG) and FCAW (Flux-Core) welding in all positions (1F-4F, 1G-4G) on a wide variety of custom products - structural components, tanks, equipment frames, wear parts, ducting, and other specialty fabrications.
• Handle assignments of increasing complexity - multi-pass welds, varied joint configurations, and different product geometries - with minimal supervision.
• Weld on carbon steel, stainless steel, aluminum, and AR plate as assigned, selecting and verifying the correct WPS, filler metals, and shielding gases for each application before beginning work.
• Consistently produce welds that meet applicable code and drawing acceptance criteria.
• Perform structural and custom fit-up and assembly independently using layout tools and measuring instruments, working from drawings and work orders across a variety of product geometries and sizes.
• Use tape measure, combination square, torpedo level, framing square, and other layout tools to establish accurate positioning and verify dimensional compliance and squareness before tacking.
• Perform tack welding and weld sequencing to secure assemblies across varied product types and material thicknesses.
• Prepare weld joints using grinders, wire wheels, and flap discs, selecting appropriate tooling and abrasives for the material - including contamination-prevention practices for stainless steel.
• Identify and report fit-up discrepancies, dimensional issues, or missing information to the Shop Lead before proceeding.

• Read and interpret fabrication drawings, weld symbols, dimensions, tolerances, bills of material, and general notes to understand the full scope of an assigned job.
• Extract weld requirements, assembly details, and dimensional data from drawings to set up and execute assigned work correctly.
• Identify and communicate drawing errors, missing information, or material conflicts to the Shop Lead before work proceeds.

• Verify joint cleanliness, fit-up condition, and WPS parameters before beginning each weld assignment.
• Perform thorough self-inspection of completed welds and assembled components against drawing requirements and applicable acceptance criteria before releasing work.
• Report weld defects, non-conformances, or quality concerns to the Shop Lead immediately.

• Provide informal support and guidance to Welder / Fitter 1 and apprentice personnel on fit-up methods, material handling, and drawing interpretation.
• Operate welding equipment, wire feeders, power sources, cutting tools, and associated tooling proficiently and safely; perform pre-use…
