鎢極氣體保護電弧焊(英語:Gas tungsten arc welding,簡稱GTAW焊),或稱鎢極惰性氣體保護焊(英語:tungsten inert gas welding,簡稱TIG焊),是一種以非熔化鎢電極進行焊接的電弧焊接法。進行GTAW焊時,焊接區以遮護氣體阻絕大氣汙染(普遍使用氬等惰性氣體),並通常搭配使用焊料(填充金屬),但有些自熔焊縫可省略此步驟。焊接時,由傳導通過高度離子化的氣體(即電漿)和金屬蒸氣的電弧,作為恆流焊接電源,提供能量。
GTAW焊常用於焊接不鏽鋼和鋁、鎂、銅合金等非鐵金屬的薄板。相較於手工電弧焊和氣體保護金屬極電弧焊,它更易於控制焊接處,提高焊接品質。然而,GTAW焊較為複雜、難以精通,而且焊接速度明顯比其他焊接法緩慢。另一種類似於GTAW焊的焊接法:等離子弧焊,使用些微不同的焊炬,製造出更集中的焊接電弧,因此常被使用於自動化工藝[1]。
