Welding Processes
Six welding technologies to match every material, joint type, and production volume.
TIG Welding (GTAW)
Precision welds on thin materials and critical joints. Ideal for stainless steel, aluminum, and titanium. Clean, high-quality beads with minimal spatter.
Best for: Aerospace brackets, food equipment, medical devices, thin-wall enclosures
MIG Welding (GMAW)
High-deposition-rate process for production welding. Faster than TIG with good penetration. Pulse MIG for aluminum and spray transfer for steel.
Best for: Structural frames, machine bases, automotive brackets, general fabrication
Robotic Welding
Automated cells for consistent, repeatable welds at high volume. Fanuc, Yaskawa, and OTC Daihen robots with seam tracking and torch cleaning.
Best for: Production runs 200+ units, automotive parts, repetitive assemblies
Spot & Projection Welding
Resistance welding for sheet metal assemblies. Fast cycle times, no filler material, minimal distortion. Up to 200kVA capacity.
Best for: Sheet metal enclosures, brackets, automotive panels, wire forms
Laser Welding
High-precision, low-distortion joining with minimal heat-affected zone. Fiber and Nd:YAG laser systems for thin materials and hermetic sealing.
Best for: Medical instruments, sensors, battery housings, precision enclosures
Flux-Cored Arc Welding
High-deposition welding for heavy structural work. Self-shielded or gas-shielded options. Excellent for thick plate and positional welding.
Best for: Heavy equipment, structural steel, pressure vessels, pipe welding
What We Fabricate
From simple brackets to turnkey multi-component assemblies — our factories handle the full fabrication workflow.
Structural Frames & Bases
Machine bases, equipment frames, chassis, and structural supports. Up to 6m long, 10 tons. Stress-relieved and precision-machined after welding.
Sheet Metal Weldments
Enclosures, cabinets, housings, guards, and covers. Laser-cut, bent, and welded with blended joints for cosmetic finish.
Pipe & Tube Assemblies
Manifolds, headers, exhaust systems, and pipe spools. CNC tube bending, orbital welding, and pressure testing available.
Precision Weldments
Fixtures, jigs, tooling, and aerospace brackets. Tight-tolerance welding with post-weld CNC machining to hold critical dimensions.
Heavy Plate Fabrication
Tanks, hoppers, chutes, and pressure vessels. Plate rolling, multi-pass welding, NDE inspection, and ASME code compliance.
Multi-Component Assemblies
Complete assemblies combining castings, machined parts, sheet metal, and hardware. Full BOM procurement through final assembly.

Why Vietnam for Welding Fabrication?
Deep Welding Talent Pool
Vietnam's shipbuilding and oil & gas industries have trained thousands of certified welders. Many hold 6G pipe qualifications and AWS certifications.
Competitive Pricing
Fabrication shop rates of $12–20/hr. Savings come from lower labor and overhead costs — not from cutting corners on quality.
Zero US Tariffs
No Section 301 surcharges on Vietnamese fabrications. Steel weldments from China face 25%+ tariffs — from Vietnam, standard MFN rates only.
Full-Service Shops
Cut, bend, weld, machine, finish, and assemble under one roof. Fewer handoffs means faster delivery and better quality.
