Tungsten Inert Gas welding (TIG) also known as GTAW is a unique welding process that uses an unconsumable tungsten electrode to create an arc of electricity between it and the parent material while using a shielding gas, typically Argon. When the arc is struck a weld, puddle is formed and can fuse two materials together or a filler material can be added.  

GTAW Tig Welding in process


TIG welding can produce much stronger welds compared to laser welding. Some important factors to note when wanting products GTAW welded:

  • Parts must have enough material to where they will not distort.
  • Thicker walled parts so burn through is kept minimal.
  • Weld joints or areas are easy to access to stick the torch into without arcing out in unwanted areas.

TIG welding allows for more penetration into the parent material giving the welded area more strength. Parts or assemblies that are subject to large amounts of force and stresses benefit more from a TIG weld over a Laser weld. Our capabilities allow us to TIG weld with as little as 1/10th of an amp leaving parts with minimal excess material for little secondary machining, buffing, or polishing.

Common applications include welding carbon steel, aluminum, stainless steel, and titanium alloys where the integrity is critical. Our customers in the medical, aerospace, and food industries can greatly benefit from this type of welding.
