GTAW(純Ar氣體保護(hù))：建議采用TIG-R31(含V)焊絲，直徑2.5mm，電流100～140A。如果有一定壁厚，管徑不是很小的話，建議采取GTAW+SMAW。SMAW：焊條采用R337，規(guī)格可以按實(shí)際情況來(lái)定。焊接完成后清理飛濺，加熱至350～450℃，保溫并緩冷的后熱措施。12Cr1MoV采用相應(yīng)成分的耐熱鋼焊條，如R310、R312、R317、R316Fe，焊前預(yù)熱250～350℃，焊后回火處理710～750℃。焊補(bǔ)缺陷或焊后不能進(jìn)行熱處理時(shí)，也可采用奧氏體鋼焊條，如A302、A307。這時(shí)，由于焊縫與母材膨脹系數(shù)不同，同時(shí)在長(zhǎng)期高溫工作時(shí)還可發(fā)生碳的擴(kuò)散遷移現(xiàn)象，而易于導(dǎo)致在融合區(qū)發(fā)生破壞。將精密鋼管送入精密鋼管機(jī)組，經(jīng)多道軋輥滾壓，精密鋼管逐漸卷起，形成有開(kāi)口間隙的圓形精密鋼管，調(diào)整擠壓輥的壓下量，使精密鋼管間隙控制在1~3mm，并使焊口兩端齊平。如間隙過(guò)大，則造成鄰近效應(yīng)減少，渦流熱量不足，精密鋼管晶間接合不良而產(chǎn)生未熔合或開(kāi)裂。如間隙過(guò)小則造成鄰近效應(yīng)增大，精密鋼管熱量過(guò)大，造成精密鋼管燒損;或者精密鋼管經(jīng)擠壓、滾壓后形成深坑，影響精密鋼管表面質(zhì)量。
