Our CWI Welding Alloys transform into MIG, TIG and SUB-ARC Welding Technologies

CWI MIG Welding

CWI MIG ( Metal Inert Gas ) weld many types of metals: carbon steel, stainless steel, cobalt, nickel,copper, aluminum, silicon bronze, magnesium & other alloys. This process offers good productivity due to high deposition rates.

Dia: .023" .030" .035" .045" 1/16"
  0.60mm 0.70mm 0.90mm 1.14mm 1.60mm

Spools: 2lb(0.907Kg) to 350lb(158.75Kg)

CWI TIG Welding

CWI TIG (Tungsten Inert Gas) is a weld process capable of producing the highest quality welds and control. It is the process of choice for pipe roots and other difficult weld joint configurations. It is widely used for weld overlay due to good dilution control.

Dia: 1/16" 3/32" 1/8" 5/32" 3/16"
  1.60mm 2.40mm 3.20mm 4.00mm 4.76mm

Tubes: 10 lb(4.53Kg) or Bulk Packaging: 400lb(181.43 Kg)


CWI SUB ARC (submerged arc welding) welding has deep weld penetration. Minimal welding fume or weld flash is emitted. No edge preparation is necessary depending on joint configuration and required penetration.

Dia: 5/64" 3/32" 1/8" 5/32"
  2.00mm 2.40mm 3.20mm 4.00mm

Coils : 60lb(27.21Kg) & 120lb(54.43Kg)
