Fitter/Welder II

About the role

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.

Responsibilities

• Production Welding - All-Position MIG & Flux-Core
• 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.
• Select and verify 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.
• Fit-Up & Assembly
• 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.
• 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.
• Drawing & Blueprint Interpretation
• 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.
• Weld Quality & Self-Inspection
• 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.
• Team Support, Equipment & Safety
• 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 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.

Requirements

• High school diploma or equivalent.
• 5-8 years of production welding and/or fabrication experience across multiple product types.
• Active welder performance qualifications in all positions (1F-4F, 1G-4G) using GMAW (MIG) and FCAW (Flux-Core) per applicable welding code or company WPS, current and documented.
• Demonstrated ability to perform structural fit-up and assembly independently using measuring and layout tools.
• Ability to read and interpret fabrication drawings and standard weld symbols and apply them to layout, fit-up, and welding.
• Proficiency with angle grinders and hand tools for material preparation and weld finishing across multiple material types.
• Reliable attendance, strong work ethic, and a commitment to producing quality work safely.

Preferred

• Exposure to a broad range of fabricated product types - structural steel, tanks, equipment frames, ducting, or wear components.
• Familiarity with filler metal and shielding gas selection for carbon steel, stainless steel, and aluminum.
• AWS Certified Welder credential and/or OSHA 10 General Industry certification.
