不銹鋼的使用越來(lái)越普遍,不論生活還是生產(chǎn)中,因此對(duì)它的了解需要更深入,本文來(lái)探討不銹鋼材質(zhì)的常用焊接方法。首先,手工焊接。手工焊是一種特別普遍的、常用的,同時(shí)也是操作簡(jiǎn)單使用方便的焊接法。電弧的長(zhǎng)度可以依靠操作者手工來(lái)進(jìn)行合理調(diào)節(jié),而調(diào)節(jié)則是根據(jù)電焊條和需要焊接的工件之間的縫隙來(lái)進(jìn)行,根據(jù)縫隙的大小調(diào)節(jié)電弧的長(zhǎng)度。焊條不僅可以作為焊接不銹鋼材質(zhì)的工具,同時(shí),它在一定的情況下也可以作為焊縫的一種有效填充材料。而這種材料,可以更好地接合不銹鋼工件,達(dá)到更好的兼容性。其次,金屬極氣體保護(hù)焊。金屬氣體保護(hù)焊是一種自動(dòng)氣體保護(hù)電弧焊。在使用此種方法的過(guò)程中,電弧在保護(hù)氣體約束下,在焊絲和不銹鋼工件之間進(jìn)行燃燒焊接。機(jī)械焊接設(shè)備送入的焊絲就是一根根焊條,通過(guò)電弧下融化為液體不銹鋼。鑒于MAG焊接法的通用性和特殊性兼有的特殊性能,是當(dāng)今不銹鋼焊接行業(yè)使用**為***的一種焊接法。而且,因?yàn)槠渚邆涠囗?xiàng)優(yōu)點(diǎn),在很長(zhǎng)一段時(shí)間內(nèi)也一定是***的焊接方法。再次,鎢極惰性氣體保護(hù)焊。在這種使用方法中,電弧產(chǎn)生在穩(wěn)定的鎢電焊絲和不銹鋼材質(zhì)工件。當(dāng)母材中碳、硫、磷等元素的含量偏高時(shí)，焊縫中容易產(chǎn)生裂紋，應(yīng)選用抗裂性能好的堿性低氫型焊條。</p><div

不能用一般氬弧焊的連續(xù)送絲手法來(lái)進(jìn)行焊接，如果一次熔化的焊絲過(guò)多，涂層熔化的也多，熔渣和熔池的鐵液就更難分清，易在背面產(chǎn)生夾渣、未熔合、咬邊及未焊透等缺點(diǎn)。進(jìn)口焊絲除可以采用上述國(guó)產(chǎn)焊絲的斷續(xù)送絲手法外，由于進(jìn)口的焊絲熔渣和鐵液流動(dòng)性較好，也可以采用連續(xù)送絲的手法焊接，但不同于一般氬弧焊連續(xù)送絲方法的是連續(xù)送絲也是送到電弧前面由焊絲自然熔化后流入熔池，而不能把焊絲直接送到熔池里面與熔池直接接觸，否則背面容易出現(xiàn)未熔化的焊絲頭。這種連續(xù)送絲手法焊接速度快，特別適合薄壁管的焊接。（4）運(yùn)弧手法國(guó)產(chǎn)的涂層焊絲焊接時(shí)電弧左右擺動(dòng)幅度要小，控制熔池的熔渣不會(huì)很快凝固。焊絲藥皮的凝固點(diǎn)比母材高，藥皮首先凝固，包住熔池中的鐵液，使鐵液不易流動(dòng)，同時(shí)對(duì)鐵液進(jìn)行保護(hù)。如果擺動(dòng)幅度過(guò)大，電弧運(yùn)動(dòng)到坡口一側(cè)時(shí)，另一側(cè)熔渣就會(huì)凝固，電弧回來(lái)后短時(shí)間內(nèi)已經(jīng)凝固的熔渣不會(huì)很快熔化，而熔化的焊絲鐵液在凝固熔渣的阻礙下不能充分及時(shí)熔化坡口邊緣，就容易形成背面熔合不良和夾渣、咬邊缺點(diǎn)。因此在電弧左右擺動(dòng)時(shí)，擺動(dòng)幅度不要太寬，電弧能熔化坡口邊緣就行。電弧運(yùn)動(dòng)到右邊時(shí)，加一滴焊絲，再運(yùn)動(dòng)到左邊時(shí)加一滴焊絲。湖南GGG70L焊條工廠</p><p
