gas tungsten arc welding, gas-tungsten arc welding, GTAW, tungsten inert gas welding, tungsten inert-gas welding, TIG welding, GTA welding, TIG-welding, WIG welding, tungsten arc welding, gas-shielded arc welding with non-consumable tungsten electrode
kaarkeevituse protsess/operatsioon, kus keevituskaar põleb mittesulava volframelektroodi otsa ja keevisvanni vahel ja kaarevahemikku kaitstakse gaasiga (taval. argoon või heelium) või gaasiseguga (vrd kaitsegaas-metallkaarkeevitus; MIG-keevitus; MAG-keevitus), an arc welding process that produces coalescence of metals by heating them with an arc between a tungsten (non-consumable) electrode and the work; shielding is obtained from a gas or gas mixture (compare: gas metal arc welding/GMAW; MIG-welding; MAG-welding)
