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。安徽鑄鐵拉延焊條銷售廠焊接過(guò)程中，空氣中的氧、氮及水蒸氣浸入焊縫，會(huì)給焊縫帶來(lái)不利的影響。</p><div

6）為避免在接頭收弧時(shí)產(chǎn)生縮孔，應(yīng)盡量采用短弧焊，焊擺動(dòng)要均勻，要保證藥芯焊絲的焊接冶金反應(yīng)過(guò)程和脫渣過(guò)程充分進(jìn)行，焊接速度應(yīng)與送絲頻率成正比。收弧時(shí)不要向前移動(dòng)太遠(yuǎn)，應(yīng)斜向前收弧，避免產(chǎn)生弧抗。4、結(jié)束語(yǔ),根部焊道采用藥芯焊絲手工鎢極氬弧焊時(shí)，不僅改善了背面成形，提高了焊接質(zhì)量，而且節(jié)約了氬氣和大量輔助用工，降低了成本，提高了生產(chǎn)效率，從而可替代以往的手工鎢極氬弧焊填充實(shí)芯焊絲背面充氬保護(hù)的焊接方法。特別是焊接固定管口、死口連頭等背面充氬保護(hù)困難的位置時(shí)，其優(yōu)越性能更為***。采用藥芯焊絲工藝性能好，焊接工藝操作簡(jiǎn)便，電弧穩(wěn)定、飛濺小、脫渣容易、焊縫成形美觀，其熔敷金屬力學(xué)性能達(dá)到了相關(guān)標(biāo)準(zhǔn)的規(guī)定。此工藝方法可應(yīng)用于其它奧氏體不銹鋼管子的打底層及蓋面層的焊接，值得在火力發(fā)電廠安裝工程中推廣應(yīng)用。</p><p> 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(lái)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(shuō)明熔池溫度過(guò)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(shuō)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(guò)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。。焊條焊接時(shí)，焊芯金屬占整個(gè)焊縫金屬的一部分。</p><div

在火力發(fā)電廠安裝中，采用藥芯焊絲對(duì)奧氏體不銹鋼管道進(jìn)行打底焊接，背面不用充氬保護(hù)，節(jié)省了大量的氬氣及充氬輔助工具。具有工藝性能良好、操作方便、焊接質(zhì)量穩(wěn)定的特點(diǎn)。在不易進(jìn)行背面充氬保護(hù)的管道焊接作業(yè)及高空作業(yè)時(shí)其優(yōu)點(diǎn)更為突出，值得在火力發(fā)電廠安裝工程中推廣應(yīng)用。1、焊接材料與工藝本次試驗(yàn)中母材采用1Cr18Ni9奧氏體不銹鋼，規(guī)格為Ф42mm×5mm，化學(xué)成分及力學(xué)性能見表1、表2。焊絲為昆山京群焊材科技有限公司生產(chǎn)的GTS-F308L藥芯焊絲，符合AWS-95R308LT1-5及GB/T17853-99R308LT1-5標(biāo)準(zhǔn)。焊絲規(guī)格為Ф×915mm，藥芯焊絲熔敷金屬的化學(xué)成分見表3。坡口尺寸的選擇坡口型式、對(duì)口參數(shù)及焊道設(shè)計(jì)見附圖。由于奧氏體不銹鋼的導(dǎo)熱系數(shù)小而線膨脹系數(shù)大，焊接時(shí)變形大。如果在焊接時(shí)選用的坡口較大，則將會(huì)增多填充金屬，增加焊的擺動(dòng)距離，降低焊接速度，加大了變形量，增加了焊縫在高溫段的停留時(shí)間，增加了產(chǎn)生晶間腐蝕及熱裂紋的可能性，所以在保證焊縫質(zhì)量及焊工易操作的前提下，應(yīng)適當(dāng)減少坡口尺寸。經(jīng)過(guò)反復(fù)實(shí)踐，將坡口尺寸選擇為55°±5°。對(duì)口間隙也適當(dāng)增大，有利于熔渣流到焊縫根部以保護(hù)根部焊縫不受氧化。酸性焊條的藥皮中含有較多的二氧化硅、氧化鐵及氧化鈦，氧化性較強(qiáng)，因而焊縫金屬塑性和韌性較低。安徽鑄鐵拉延焊條銷售廠</p><p
