</p> <p> 原料質(zhì)量好壞是保證不銹鋼焊管質(zhì)量的關(guān)鍵，因此，凡是進(jìn)廠的原料在使用之前都要進(jìn)行檢驗(yàn)，驗(yàn)收質(zhì)量合格單，觀察外表，山東2507不銹鋼無(wú)縫焊管供應(yīng)，山東2507不銹鋼無(wú)縫焊管供應(yīng)，測(cè)量寬度和厚度是否均等，特別是直拔料，除檢驗(yàn)寬度、厚度外，還要進(jìn)行化學(xué)成分和拉伸試驗(yàn)的檢查，合格后才能正常投入生產(chǎn)。

不銹鋼焊管廠家的焊接操作中，大家市場(chǎng)面臨三大常見(jiàn)問(wèn)題(第三個(gè)問(wèn)題），縫不合格、未焊透或被燒穿、裂紋和氣孔，下面大家跟隨江蘇進(jìn)百洪來(lái)了解這些問(wèn)題的原因和解決方法吧，掌握正確的焊接技術(shù)，從而科學(xué)安全***的完成焊接任務(wù)。 </p> <p> <span style="display:none;"></span>（三）裂紋和氣孔。裂紋的出現(xiàn)頻率很高，一般裂紋分為熱裂紋和冷裂紋兩種。由于液體金屬在凝固過(guò)程中或略低于固相線溫度下，產(chǎn)生沿晶間邊界的、斷口上就會(huì)形成具有氧化色的熱裂紋。在固態(tài)時(shí)發(fā)生相變，或有擴(kuò)散氫存在，以及冷卻時(shí)在過(guò)大的焊接收縮應(yīng)力作用下，就會(huì)生成的具有穿晶性質(zhì)的、斷口發(fā)亮、沒(méi)有氧化色的冷裂紋。如果在使用焊絲時(shí)不合乎標(biāo)準(zhǔn)，焊接時(shí)高溫停留時(shí)間過(guò)長(zhǎng)，造成氧化、過(guò)熱和晶粒度過(guò)度長(zhǎng)大，材料本身雜質(zhì)較多，或材料本身易淬硬時(shí)均易產(chǎn)生裂紋。

必須指出的是，雖然中國(guó)經(jīng)濟(jì)增速放緩，但因?yàn)閷?duì)比基數(shù)的不斷提高，其體量規(guī)模依然巨大。同樣道理，盡管中國(guó)不銹鋼工業(yè)焊管需求增幅由兩位數(shù)回落至5%左右，但其***數(shù)量依然驚人，現(xiàn)在每1個(gè)百分點(diǎn)的增幅，就意味著增加粗鋼需求900萬(wàn)噸，相當(dāng)于上世紀(jì)90年代初期10個(gè)百分點(diǎn)的增長(zhǎng)水平。對(duì)比基數(shù)不斷提高、經(jīng)濟(jì)增速回落觸底，將使得新一年中國(guó)粗鋼需求體量依然規(guī)模巨大。初步測(cè)算，2015年中國(guó)粗鋼實(shí)際需求數(shù)量（含直接出口與未納入統(tǒng)計(jì)的產(chǎn)量，下同）將躍上9億噸，雄據(jù)全球不銹鋼焊管需求的半壁河山。
