补充资料：埋弧焊
利用在焊剂层下燃烧的电弧进行焊接的方法（见图）。在焊接过程中,焊剂熔化产生的液态熔渣覆盖电弧和熔化金属，起保护、净化熔池、稳定电弧和渗入合金元素的作用。埋弧焊分为自动埋弧焊和半自动埋弧焊两种。前者应用较广泛,焊接电流可达600～2000安，焊接效率很高。埋弧焊是一种适于大量生产的焊接方法，广泛用于焊接各种碳钢、低合金钢和合金钢，也用于不锈钢和镍合金的焊接和表面堆焊。为了提高焊接效率和扩大使用范围，埋弧焊的电极可采用双丝、三丝、带极(用于堆焊)，还可在焊剂中添加金属粉等。焊剂层下的电弧与焊件接口的对正和调整，可用工业电视观察或用激光跟踪等方法探测。埋弧焊的焊接效率高,焊缝光洁，无飞溅，少烟尘，无电弧闪光，劳动卫生条件好，设备成本较低。缺点是限于平焊和长焊缝。与气体保护电弧焊相比，埋弧焊电弧不可见，接头装配要求较高，应用灵活性也较差。
