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
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.
- TIG & MIG
- 6061 · 5083 · 5052
- Full-penetration, pressure-grade
Live from our U.S. floorWelding Processes
GTAW (TIG)
Gas Tungsten Arc Welding for controlled aluminum and stainless applications. TIG is used throughout FWM's cryogenic heat exchanger and fabricated-assembly work where joint quality and heat input matter.
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 support consistent positioning and weld sequence across recurring OEM builds, with inspection requirements defined by the approved program.
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.

Frequently Asked Questions
Planning your project
Prepare a production welding RFQ
Give the welding team the drawing requirements and the complete assembly context, including work needed before and after welding.
- What helps FWM review a heavier aluminum weldment?
- Send the alloy and temper, material thicknesses, joint details, weld symbols and overall assembly dimensions. Include the interfaces and acceptance criteria that matter to the finished part. FWM confirms process and equipment fit for the actual drawing.
- How do I specify the work around the weld?
- Identify cutting, forming, machined features, component mounting and finish requirements alongside the weld details. List any required qualification records, inspection methods and traceability documents so those deliverables can be confirmed in the program scope.
