TIG stands for Tungsten Inert Gas welding. It is a welding process that uses a non-consumable tungsten electrode to produce the weld. The “TIG” acronym refers to the tungsten electrode and the inert gas, typically argon or helium, that shields the weld from oxidation and contamination.
In TIG welding, an arc is formed between the tungsten electrode and the workpiece, which heats the metal and creates a molten pool.
The welder then adds filler metal to the pool to create the final weld. TIG welding is known for its precision and ability to produce high-quality welds and is often used in applications that require high accuracy, such as in the aerospace, automotive, and medical industries.
