WebApr 13, 2024 · Gas tungsten arc welding (GTAW) GTAW or TIG welding is often considered to be the most difficult. Tungsten electrodes create the arc. Inert gases like argon or helium or a mix of the two are used to protect the shield. Filler wires add molten material if needed.
Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or … See more After the discovery of the short pulsed electric arc in 1801 by Humphry Davy and of the continuous electric arc in 1802 by Vasily Petrov, arc welding developed slowly.
