不銹鋼的使用越來越普遍,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，山東TM-2000焊條供貨廠,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，山東TM-2000焊條供貨廠。在使用此種方法的過程中,電弧在保護(hù)氣體約束下，山東TM-2000焊條供貨廠,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。</p><div

防止出現(xiàn)單邊未熔合。在填充焊絲時(shí)，應(yīng)將焊絲送到熔池根部并向下輕壓一下，以保證根部熔透及根部?jī)?nèi)成形。（2）焊絲端部應(yīng)始終處于氬氣保護(hù)之中，防止合金元素的氧化、燒損。為使熔渣盡快浮出，根據(jù)情況可用焊絲對(duì)高溫熔池進(jìn)行適當(dāng)攪拌，不宜依靠降低焊速來促使熔渣浮出。焊后在焊縫表面形成的熔渣薄而脆，高溫時(shí)極易自行脫落，故焊接時(shí)應(yīng)戴好防護(hù)眼鏡，防止灼傷眼睛。（3）要獲得美觀均勻的焊縫很大程度上取決于正確掌握熔池的溫度。當(dāng)發(fā)現(xiàn)熔池增大出現(xiàn)下凹，說明熔池溫度過高，這時(shí)應(yīng)迅速減少焊與工件的夾角，并加快焊接速度。當(dāng)熔池小焊縫窄而高時(shí)，說明熔池溫度低，這時(shí)應(yīng)增大焊與工件的夾角，減慢焊接速度，減少焊絲添加量。（4）1Cr18Ni9不銹鋼在450~800℃溫度區(qū)加熱，常發(fā)生沿晶界的腐蝕破壞，稱為晶間腐蝕。為防止打底層焊縫金屬產(chǎn)生晶間腐蝕，應(yīng)以快焊快冷為原則，盡量采用小的焊接熱輸入、快速焊、短弧焊、小幅擺動(dòng)。（5）焊接時(shí)焊要等速移動(dòng)，禁止抖動(dòng)。焊絲與工件表面的夾角在25°左右，既可保證藥芯焊絲冶金反應(yīng)的充分性，又可避免填充金屬的過熱。鎢極端頭與熔池表面的距離應(yīng)保持在3mm左右，使操作者的視線寬廣，送絲方便，避免焊縫夾鎢。。</p><div

在坡口兩側(cè)停留時(shí)間要短，左右擺動(dòng)運(yùn)弧速度要慢，向前焊接速度要稍快，這樣熔池溫度較低，里口不易咬邊和塌陷，同時(shí)避免焊縫金屬過熱。進(jìn)口焊絲由于熔渣和鐵液流動(dòng)性較好，在運(yùn)弧時(shí)基本和一般氬弧焊相近，但在左右擺動(dòng)時(shí)不可過快。（5）仰位置焊接方法國(guó)產(chǎn)焊絲由于涂層較厚，鐵液流動(dòng)性差，不易往下淌，在焊接水平固定口的仰焊位置時(shí)只要把焊絲送到坡口的背面，背面的焊縫高度就能凸出來，其他焊接手法按照前述4點(diǎn)操作就行。進(jìn)口焊絲仰焊位置操作方法：電弧在坡口的根部，焊絲在坡口的背面，并且始終在電弧的前端，一定要多送焊絲，送的少就會(huì)因?yàn)殍F液不夠造成內(nèi)凹，但又不能送入熔池里。同時(shí)焊前進(jìn)的速度要小，如果速度太快，內(nèi)口每個(gè)焊紋之間連接不上，就會(huì)在焊紋之間形成咬邊和內(nèi)凹缺點(diǎn)。間隙較大時(shí)，焊絲可以隨電弧一起擺動(dòng)送絲。進(jìn)口焊絲鐵液流動(dòng)性好，仰焊位置內(nèi)口焊縫高度凸出，比國(guó)產(chǎn)焊絲難度較大，成形沒有國(guó)產(chǎn)的好。（6）接頭方法收弧比較好收在坡口側(cè)，否則容易出現(xiàn)縮孔或者夾渣。比較好把接頭打磨成斜坡，否則容易出現(xiàn)接頭熔合不好或者內(nèi)口臺(tái)階狀焊道。焊接接頭時(shí)先熔化接頭再添加焊絲焊接，如果焊接接頭時(shí)背面熔渣已經(jīng)脫落，此時(shí)的接頭速度要較快。</p><div
