釷鎢電極是一種廣泛使用的添加氧化物電極，它有比純鎢電極及其它氧化物添加電極還要優(yōu)越的綜合焊接性能，在長期使用過程中，它是其它氧化物電極所不可替代的。釷鎢電極操作簡便，電流負荷大，引弧容易，電弧穩(wěn)定，斷弧間隙大，損耗小，使用壽命長，再結(jié)晶溫度更高，導(dǎo)電率更好，機械切割性能好。釷鎢電極廣泛使用于碳鋼、不銹鋼、鎳合金和鈦金屬焊接，是高品質(zhì)焊接的首選材料。 Thorium-TungstenElectrodeiswidelyusedasanadditiveoxideelectrode,havingmuchmoreadvancedcomprehensiveweldingperformancethanthepropertiesofpuretungstenelectrodeandotheradditiveoxideelectrodes.Itcannotbereplacedbyotheroxideelectrodesduringthelongusingprocess.Itcanbeoperatedeasily,hasahighcurrentloadandproducesarceasilyandsteadily.Inaddition,thegapofthebreakingarcisbig,losslessandlifelonger.Ithashigherrecrystallizingtemperature,betterconductivityandmechanicalcuttingproperty.Now,Thorium-TungstenElectrodeiswidelyusedinweldingcarbonsteel,stainlesssteel,nickelalloyandtitaniummetal.Itbecomesthefirstselectionmaterialforhighqualitywelding. 牌號Model添加的氧化物OxideAddictive雜質(zhì)含量%ImpuritiesContent鎢含量%TungstenContent色標Colorstandard種類Varieties含量Content%WT10ThO20.90-1.20 0.2余量balance黃yellowWT20ThO21.80-2.20 0.2余量balance紅redWT30ThO22.80-3.20 0.2余量balance紫purpleWT40ThO23.80-4.20 0.2余量balance桔黃orange
