Aluminum Welding Fabricator (GTAW/GMAW Specialist)

Express Saint Louis

Job Description

Job Description

Aluminum Welding Fabricator (GTAW/GMAW Specialist) A Day in the Shop

You clock in to a clean, organized bay and scan the day’s mix of projects: a production run of aluminum subassemblies and a one-off custom fixture. You review prints, mark weld symbols, and prep joints. You dial in your parameters—deciding between pulse MIG or a tight, controlled TIG puddle—then fit, tack, and weld. After blending and finishing, you verify bead appearance, penetration, and dimensions before moving the assembly with an overhead crane for final checks. By mid-day, you’re troubleshooting a porosity issue on a machined component, and by afternoon you’re perfecting distortion control on thin sheet. It’s hands-on, precise, and satisfying work—done with pride.

We’re hiring two welders to support a growing manufacturing team working with aluminum in both production and custom fabrication environments. We welcome candidates across the experience spectrum who have solid welding fundamentals and a drive to master aluminum fabrication.

What You’ll Do
  • Perform MIG (GMAW) and TIG (GTAW) welding on aluminum components and assemblies
  • Handle full-cycle fabrication: fit-up, welding, grinding, blending, finishing, and assembly
  • Prep aluminum joints and surfaces for quality welds
  • Set and adjust welding equipment and parameters for aluminum work
  • Read and interpret blueprints, fabrication drawings, and weld symbols
  • Fit and align fabricated components and assemblies to print
  • Inspect welds for appearance, penetration, and dimensional accuracy
  • Identify and correct defects such as porosity, lack of fusion, and distortion
  • Operate grinders, saws, drills, fixtures, cranes, and related fabrication tools
  • Maintain a safe, clean, and efficient work area
  • Meet production goals while upholding high-quality standards
Qualifications
  • Previous MIG and/or TIG welding experience
  • Aluminum welding experience strongly preferred
  • Fabrication and precision fit-up experience preferred
  • Blueprint and weld symbol literacy preferred
  • Strong mechanical aptitude and attention to detail
  • Comfort working independently and collaboratively
  • Ability to perform physically demanding manufacturing work
  • Welding certification, technical training, or equivalent hands-on experience is a plus
Senior-Level Focus (If This Is You)
  • 5+ years of professional welding and fabrication experience
  • Deep aluminum MIG (GMAW) and TIG (GTAW) expertise
  • Experience with aluminum sheet, plate, extrusion, and machined parts
  • Mastery of weld prep, heat input, distortion management, and contamination control
  • Ability to troubleshoot porosity, cracking, lack of fusion, and distortion
  • Proven precision fit-up on complex fabricated assemblies
  • Familiarity with AWS D1.2 Aluminum Structural Welding Code
Who Thrives Here

Dependable welders who take pride in clean, accurate work. You don’t need to check every preferred box to apply—strong fundamentals, reliability, and a willingness to learn matter. We’re serious about quality and safety, and we value teammates who are too.

Compensation

Competitive pay commensurate with your welding experience, skill level, and demonstrated fabrication ability.
