Heavy Welding & Fabrication Highlights
|Arc/Resistance Welding Process||FCAW (Flux Core Arc Welding)
This process uses similar equipment as GMAW but in place of standard solid wire uses wire consisting of a steel electrode surrounding a powder fill material.
GMAW (Gas Metal Arc Welding)
Also known as metal inert gas or MIG welding.
GTAW (Gas Tungsten Arc Welding)
Also known as Tungsten Inert Gas (TIG) welding. This process uses a
Metal Inert Gas welding, also referred to as Gas Metal Arc Welding.
Also known as Tube Arc Welding, this process is used for the circumferential welding of tubes, pipes and round stock.
SMAW (Shielded Metal Arc Welding)
Also known as Manual Metal Arc Welding or Stick welding. This process uses a consumable electrode rod, which as the filler material, is covered in flux and protects the weld area from oxidation and contamination.
Spray welding is a process where weld material is sprayed onto a workpiece. This process can be used to apply wear and heat
Submerged Arc Welding (SAW) is a welding process in which the arc is struck beneath a layer of flux which increases arc quality and blocks atmospheric contaminants.
Tungsten Inert Gas welding. Also referred to as Gas Tungsten Arc Welding.
