补充资料:焊接:等离子弧焊
利用等离子弧作为热源的焊接方法(见图 等离子弧焊(穿孔式) )。气体由电弧加热產生离解﹐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﹑发热量和温度都高於一般电弧﹐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氬。根据各种工件的材料性质﹐也有使用氦或氬氦﹑氬氢等混合气体的。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﹐主要用於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﹐用於焊接。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﹐多用於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﹐多用於 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﹐特别适合於0.02~1.5毫米的薄板焊接。等离子弧焊接属於高质量焊接方法。焊缝的深/宽比大﹐热影响区窄﹐工件变形小﹐可焊材料种类多。特别是脉衝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。
