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（其中兩個(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> （一）焊縫不合格。焊縫不合格是因焊接工藝參數(shù)選擇不當(dāng)，或操作技術(shù)不熟練，導(dǎo)致焊縫高低寬窄不一，焊縫成形不良，背面焊縫下凹。造成焊縫減弱過(guò)多，使焊縫強(qiáng)度不夠。 </p> <p> （二）未焊透或被燒穿。未焊透是主要有以下原因，一是電流過(guò)小，二是操作技術(shù)不熟練，焊接速度太快，對(duì)接間隙小，三是電弧過(guò)長(zhǎng)或電弧未對(duì)準(zhǔn)焊縫等，如果導(dǎo)致焊絲與基體金屬未熔合在一起或焊接金屬中局部未熔合的時(shí)候，該部位應(yīng)及時(shí)進(jìn)行補(bǔ)焊。燒穿的原因是因焊接電流過(guò)大，熔池溫度過(guò)高，焊絲加入不及時(shí)，帶鋼對(duì)接間隙過(guò)大，焊接速度過(guò)慢等，導(dǎo)致焊縫上出現(xiàn)單個(gè)或連續(xù)的穿孔。使焊縫強(qiáng)度減弱，從而被燒穿。 </p> <p> <br /> </p><p> 不銹鋼焊管工藝技術(shù)——高頻焊。 </p> <p> 頻焊接具有較電源功率，對(duì)不同的材質(zhì)、外徑壁厚的鋼管都能達(dá)到較高的焊接速度。與氬弧焊相比，是其比較高焊接速度的10倍以上。因此，生產(chǎn)一般用途的不銹鋼管具有較高的生產(chǎn)率。 </p> <p> 因?yàn)楦哳l焊接速度高，給焊管內(nèi)毛刺的去除帶來(lái)困難。目前，高頻焊不銹鋼管尚不能為化工、核工業(yè)所接受，這也是其原因之一。從焊接材質(zhì)看，高頻焊可以焊接各種類型的奧氏體不銹鋼管。同時(shí)，新鋼種的開(kāi)發(fā)和成型焊接方法的進(jìn)步，也成功地焊接了鐵素體不銹鋼AISI409等鋼種。 </p> <p> <br /> 組合焊接法有：氬弧焊加等離子焊、高頻焊加等離子焊、高頻預(yù)熱加三焊炬氬弧焊、高頻預(yù)熱加等離子加氬弧焊。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="黑龍江309s不銹鋼無(wú)縫焊管加工定制,不銹鋼無(wú)縫焊管"
