如果持續(xù)時間過長，就會出現(xiàn)焊絲嚴重發(fā)紅，焊點發(fā)黑現(xiàn)象。就算能焊，焊補的時候，容易出現(xiàn)氧化，掉渣，焊不高等現(xiàn)象.，并且影響其后續(xù)加工。焊絲CO2焊編輯二氧化碳氣體保護電弧焊（簡稱CO2焊）的保護氣體是二氧化碳（有時采用CO2+O2的混合氣體）。由于二氧化碳氣體的0熱物理性能的特殊影響，使用常規(guī)焊接電源時，焊絲端頭熔化金屬不可能形成平衡的軸向自由過渡，通常需要采用短路和熔滴縮頸爆斷、因此，與MIG焊自由過渡相比，飛濺較多。但如采用質(zhì)量焊機，參數(shù)選擇合適，可以得到很穩(wěn)定的焊接過程，使飛濺降低到**小的程度。由于所用保護氣體價格低廉，采用短路過渡時焊縫成形良好，加上使用含脫氧劑的焊絲即可獲得無內(nèi)部缺點的高質(zhì)量焊接接頭。因此這種焊接方法目前已成為黑色金屬材料**重要焊接方法之一。CO2立焊雙面成形焊絲型號編輯常用的焊絲型號：常見的氣體保護藥芯焊絲有：LQ122、LQ172、LQ212、LQ337、LQ423、LQ439、LQ451、LQ537、LQ582、LQ585、LQ605、LQ621、LQ666、LQ707等。一般直徑）常見的自保護藥芯焊絲有：LZ409、LZ410、LZ411、LZ414N、LZ430、LZ570、LZ590、LZ601、LZ603、LZ606、LZ632、LZ641、LZ642、LZ643、LZ650等。</p><p> 6）為避免在接頭收弧時產(chǎn)生縮孔，應盡量采用短弧焊，焊擺動要均勻，要保證藥芯焊絲的焊接冶金反應過程和脫渣過程充分進行，焊接速度應與送絲頻率成正比。收弧時不要向前移動太遠，應斜向前收弧，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，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芯焊絲背面充氬保護的焊接方法。特別是焊接固定管口、死口連頭等背面充氬保護困難的位置時，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，其熔敷金屬力學性能達到了相關(guān)標準的規(guī)定。此工藝方法可應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用。?焊接過程中產(chǎn)生很大的內(nèi)應力，易使焊縫產(chǎn)生裂紋，應選用抗裂性能好的堿性低氫焊條。</p><div
