GTAW / TIG welding

GTAW (Gas Tungsten Arc Welding) or TIG (tungsten inert gas) welding, uses a non-consumable tungsten electrode to produce arc and weld area is protected by an inert shielding gas. GTAW / TIG welding produces superior quality welds, free of defects and spatter. TIG is widely used in thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys, AC mode should be used at aluminum and magnesium welding application.

GTAW offers many advantages: no fume, low heat input, precise penetration control, for all position welding.

GTAW process is used for manual, semi-automated, fully automated and robotic welding.

Air Liquide Canada provides best combos of filler metal (BLUESHIELDTM) and shielding gas (BLUESHIELDTM and ARCALTM) for your various applications that help you to enhance quality and productivity but save cost.


Most TIG/GTAW applications can be completed using a straight Argon mix. For applications where color match or higher deposition rates are required a Helium/Argon mix would be required
