控制層間溫度對避免產(chǎn)生晶問腐蝕及熱裂紋尤為重要，并可控制焊縫根部的氧化，因此焊接時應(yīng)盡量選用小線能量快速焊。層間溫度應(yīng)控制在50~60℃。焊接工藝參數(shù)焊接前將坡口內(nèi)外邊緣10~20mm處焊件表面的油污、水、銹等清理干凈，露出金屬光澤。焊接工藝參數(shù)的選擇，見表4所示。2、焊縫外觀檢驗及性能試驗焊縫外觀成形良好，尤其是焊縫背面成形美觀，無焊瘤、未熔合、未焊透等缺點。射線檢測按照JB/T4730《承壓設(shè)備無損檢測》標準進行，II級及以上為合格，經(jīng)評定為合格。力學性能試驗按GB/T228和GB/T2653規(guī)定的試驗方法，對焊接接頭試樣進行了拉伸試驗和彎曲試驗，拉伸實驗結(jié)果如表5所示，彎曲試驗結(jié)果如表6所示。實驗結(jié)果為合格。3、焊接操作要領(lǐng)不銹鋼藥芯焊絲是利用焊絲中間的藥粉熔化后，在熔敷金屬背面和正面形成熔渣進行保護，所以根部焊接時與實芯焊絲焊接的操作方法、電弧擺動頻率、填絲量有較大區(qū)別。（1）在焊接過程中，焊要做圓弧形擺動,其目的是使鐵水和熔渣加速分離，便于觀察熔池，同時也可增加母材坡口兩側(cè)的熱輸入量，防止出現(xiàn)單邊未熔合。在填充焊絲時，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。。</p><p> 通過外力很快就形成小部份短路移動工件上去，由于熔化得少，工件與之相比大很多。溫度很快就散發(fā)掉了。焊絲溫度不會持續(xù)上升至其整段發(fā)紅，抗紅能力***。與普通焊絲相比，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。焊接接頭的強度隨著焊絲的合金元素含量變化。</p><div
