等离子弧焊　　利用等离子弧作为热源的焊接方法（见图）。气体由电弧加热产生离解，在高速通过水冷喷嘴时受到压缩，增大能量密度和离解度，形成等离子弧。它的稳定性、发热量和温度都高于一般电弧，因而具有较大的熔透力和焊接速度。形成等离子弧的气体和它周围的保护气体一般用氩。根据各种工件的材料性质，也有使用氦或氩氦、氩氢等混合气体的。等离子弧有两种工作方式。一种是"非转移弧"，电弧在钨极与喷嘴之间燃烧，主要用于等离子喷镀或加热非导电材料；另一种是"转移弧"，电弧由辅助电极高频引弧后，电弧燃烧在钨极与工件之间，用于焊接。形成焊缝的方式有熔透式和穿孔式两种。前一种形式的等离子弧只熔透母材，形成焊接熔池，多用于0.8～3毫米厚的板材焊接；后一种形式的等离子弧只熔穿板材，形成钥匙孔形的熔池，多用于 3～12毫米厚的板材焊接。此外，还有小电流的微束等离子弧焊,特别适合于0.02～1.5毫米的薄板焊接。等离子弧焊接属于高质量焊接方法。焊缝的深／宽比大，热影响区窄，工件变形小，可焊材料种类多。特别是脉冲电流等离子弧焊和熔化极等离子弧焊的发展，更扩大了等离子弧焊的使用范围。
