Gas Tungsten Arc Welding (GTAW), also known as Tungsten Inert Gas (TIG) welding, is a precise and high-quality welding process that uses a non-consumable tungsten electrode to produce the weld. An inert shielding gas, usually argon or helium, protects the weld area from atmospheric contamination. TIG welding can be used on a wide range of metals, including stainless steel, aluminum, and copper alloys. It provides excellent control over heat input and weld appearance, resulting in clean, strong, and high-integrity welds. Commonly used in aerospace, piping, and fabrication industries, TIG welding is ideal for thin materials and applications requiring superior finish and precision.
