Fitter/Welder I

About the role

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.

Responsibilities

• Production Welding - MIG & Flux-Core
• Perform GMAW (MIG) and FCAW (Flux-Core) welding on assigned workpieces, 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.
• Fit-Up & Assembly
• 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.
• Quality & Self-Inspection
• 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.
• Equipment, Safety & Housekeeping
• 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.
• 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 to take verbal direction accurately and consistently.
• Willingness to develop the complementary skill - welders growing into fit-up, or fitters pursuing welder qualification - with company support.
• Reliable attendance, strong work ethic, and a commitment to producing quality work safely.

Preferred

• Experience welding or handling stainless steel, aluminum, or abrasion-resistant (AR) plate.
• Familiarity with filler metal and shielding gas selection for carbon and stainless steel.
• Experience operating production equipment such as a band saw, cold saw, plasma table, press brake, or beamline.
• AWS Certified Welder credential and/or OSHA 10 General Industry certification.

Working Conditions

• Physical Requirements:
• Regularly stand, walk, and remain on your feet for the majority of the shift in a production shop environment.
• Frequent bending, kneeling, crouching, and reaching during welding, fit-up, grinding, and machine operation.
• Occasional lifting and carrying of materials, tooling, and components up to 50 lbs; team lifts or mechanical assists are used for heavier items.
• Sustained work requiring manual dexterity, hand-eye coordination, and physical endurance across varied fabrication tasks.
• Ability to wear and work in all required PPE - welding helmet, safety glasses, gloves, hearing protection, and protective clothing - for extended periods.
• Environmental Conditions:
• Work is performed in a custom metal fabrication shop subject to varying temperatures, noise, dust, metal particulate, and vibration.
• Regular exposure to welding fumes, arc flash, UV radiation, heat, and cutting byproducts inherent to a production fabrication environment.
• Exposure to a range of base metals - carbon steel, stainless steel, aluminum, and AR plate - each with associated handling and fume considerations.
• Proper ventilation, fume extraction, and PPE are provided and required at all times per company safety policies and OSHA regulations.

Schedule & Work Environment

Standard Monday through Friday schedule during regular facility operating hours. Occasional overtime may be required to meet production demands or project deadlines. This is an on-site position. Remote work is not applicable to the essential functions of this role.
