id="0cy34cf" class="khcont8">如間隙過大，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)生未熔合或開裂。如間隙過小則造成鄰近效應(yīng)增大，精密鋼管熱量過大，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。精密鋼管的特點就是精密度高，而且不容易生銹。但是并不是說既然精密鋼管不容易生銹我們平常就不用管它了，直接把它放在一邊就可以了。這樣做就錯了，因為如果精密鋼管平常不保養(yǎng)的話，它的使用壽命就會縮短，也會給我們精密鋼管廠帶來不必要的損失。如何對精密鋼管進行酸洗。對精密鋼管進行酸洗，在對精密鋼管進行酸洗時一都會用化學(xué)和電解兩種方法，這兩種方法可有將精密鋼管管道的氧化皮去除掉。之所以會將其分成兩種方法進行原因是由于化學(xué)清洗只可以將表面清潔的非常徹底，對于一些細縫中就很難達到人們所想的結(jié)果了。</div><p><img

GTAW(純Ar氣體保護)：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)格可以按實際情況來定。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℃。焊補缺陷或焊后不能進行熱處理時，也可采用奧氏體鋼焊條，如A302、A307。這時，由于焊縫與母材膨脹系數(shù)不同，同時在長期高溫工作時還可發(fā)生碳的擴散遷移現(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組，經(jīng)多道軋輥滾壓，精密鋼管逐漸卷起，形成有開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)生未熔合或開裂。如間隙過小則造成鄰近效應(yīng)增大，精密鋼管熱量過大，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。
