钨极气体保护电弧焊
钨极气体保护电弧焊(英语:Gas tungsten arc welding,简称GTAW焊),或称钨极惰性气体保护焊(英语:tungsten inert gas welding,简称TIG焊),是一种以非熔化钨电极进行焊接的电弧焊接法。进行GTAW焊时,焊接区以遮护气体阻绝大气污染(普遍使用氩等惰性气体),并通常搭配使用焊料(填充金属),但有些自熔焊缝可省略此步骤。焊接时,由传导通过高度离子化的气体(即等离子)和金属蒸气的电弧,作为恒流焊接电源,提供能量。
GTAW焊常用于焊接不锈钢和铝、镁、铜合金等非铁金属的薄板。相较于手工电弧焊和气体保护金属极电弧焊,它更易于控制焊接处,提高焊接品质。然而,GTAW焊较为复杂、难以精通,而且焊接速度明显比其他焊接法缓慢。另一种类似于GTAW焊的焊接法:等离子弧焊,使用些微不同的焊炬,制造出更集中的焊接电弧,因此常被使用于自动化工艺[1]。
