纯钨极
纯钨极钇钨极复合极PURETUNGSTEN/YTTRIATEDTUNGSTEN/COMPOSITEELECTRODES特色:1、纯钨电极在所有的钨电极中价格***便宜,适合在交流条件下镁、铝及其合金的焊接。2、钇钨电极在焊接时,弧束细长,压缩程度大,尤其在中、大电流条件下溶深***大,目前主要用于***和航空航天工业。3、复合电极是在钨中添加了两种或更多种的稀土氧化物,各添加物互为补充,相得益彰,使其焊接性能更出众。Characteristics:1.puretungsten,theleastexpensiveofalltungsten,isgenerallyusedintheACweldingofaluminumandmagnesiumalloys.2.YttriatedTungstenisprimarilyusedinmilitaryand***iationindustrywithnarrowarcbeam,highcompressingstrength,highestweldingpenetrationatmediumandhighcurrent.3.TheperformancesofCompositeElectrodesinweldingcanbemuchimprovedbyaddingtwoormorerareearthoxideswhicharemutuallycompletementary.)
