Product Description

Tungsten Insert Gas welding(TIG) or Gas Tungsten Arc welding(GTAW) uses a nonconsumable tungsten
Electrode which must be shielded with an inert gas. The arc is initiated between the tip of the electrode
And work to melt the metal being welded, as well as the filler metal, when used. A gas shield protects the
Electrode and the molten weld pool, and provides the required arc characteristics.
The process may employ direct current with positive or negative electrode or alternating current. In gerenal, AC is preferred for welding aluminum and magnesium. Direct current electrode negative is preferred for
Welding most other materials and for automatic welding of thick aluminum. Thin magnesium sometimes is
Welded with direct current electrode positive.
Gas tungsten arc welding is generally more expensive than SMAW due to the cost of the inert gas, and is
Only 10 to 20 perent as fast as GMAW. However, GTAW will provide the highest quality root pass, while
Accommodating a wider range of thicknesses, positions, and geometries than either SMAW or GMAW.
