2、保护焊,使用的保护气体,分CO2和CO2+Ar两种。使用的焊丝主要是锰硅合金焊丝,超低碳合金焊丝及药芯焊丝。焊丝主要规格有:0.5mm、0.8 mm、0.9 mm、1.0 mm、1.2 mm、1.6 mm、2.0 mm、2.5 mm、3.0 mm、4.0mm等。二、二氧化碳气体保护焊特点(一)MAG焊具有下列优点:1、焊接成本低:其成本只有埋弧焊和手工电弧...
CO电弧焊的保护效果CO2气体本身是一种活性气体,它的保护作用主要是使焊接区与空气隔离,防止空气中的氮气 对熔池金属的有害作用,因为一旦焊缝金属被氮化和氧化,设法脱氧是很容易实现的,而要脱氮就很困难。CO 2气保焊在CO 2保护下能很好地排除氮气。在电弧的高温作用下 (5000K以上),CO2气体全部分解成 CO+ O,...
