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內(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><p> 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)過程和脫渣過程充分進(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,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。應(yīng)按焊接性較差的不銹鋼確定焊接工藝及規(guī)范。</p><div
