Capability

Production aluminum and stainless steel welding for complex OEM assemblies

FWM provides TIG, MIG, and orbital welding for build-to-print aluminum and stainless steel weldments, structural frames, skids, enclosures, cryogenic assemblies, stainless tube assemblies, and recurring OEM production. Welding is integrated with cutting, CNC machining, forming, inspection, assembly, and shipment from one U.S. manufacturing facility.

Best for

OEMs needing repeatable aluminum or stainless weldments with documentation, traceability, and production capacity.

Product types

Welded aluminum frames, equipment skids, fabricated enclosures, extrusion-based assemblies, cryogenic assemblies, stainless steel tube and pipe assemblies, racks, carts, and finished OEM products.

Aluminum and stainless weldments FWM manufactures

Welding at FWM is structured around recurring, build-to-print production rather than one-off commodity weldments. Common categories include:

  • Large welded aluminum frames
  • Equipment skids and base structures
  • Fabricated enclosures
  • Extrusion-based assemblies
  • Cryogenic assemblies
  • Stainless steel tube and pipe assemblies
  • Racks, platforms, fixtures, and carts
  • Finished OEM products
On the floor

Clean, repeatable welds, start to finish.

Qualified welders lay down full-penetration, pressure-grade joints on aluminum and stainless assemblies, every pass run to print in our U.S. shop.

Welding Processes

GTAW (TIG)

Gas Tungsten Arc Welding for high-precision, thin-gauge aluminum and stainless applications. Clean, spatter-free joints with full penetration control. Used extensively in cryogenic heat exchanger production where weld integrity is critical to pressure containment and thermal performance.

GMAW (MIG)

Gas Metal Arc Welding for thicker structural weldments requiring high deposition rates. Production-grade MIG welding for aluminum frames, structural assemblies, and heavy fabrication where throughput matters without sacrificing weld quality.

Production Fixturing

Repeatable welding fixtures for high-volume production runs. Consistent positioning and weld quality across thousands of identical assemblies with minimal variation. Ideal for OEM programs requiring tight statistical process control.

Pulse Welding

Advanced pulse welding technology for superior control of heat input and weld pool dynamics. Reduces distortion on thin-gauge aluminum, minimizes porosity, and produces cleaner welds where the Heat Affected Zone must be tightly controlled.

Orbital Welding (Stainless Tube)

Automated orbital GTAW on stainless steel tube for consistent, repeatable, full-penetration welds. Uniform bead profile and documented, repeatable parameters make it ideal for stainless tube assemblies where weld consistency and traceability matter.
