不銹鋼焊管的三種焊接技術(shù)介紹。目前，工業(yè)上應(yīng)用的不銹鋼焊管的焊接方法主要有氬弧焊、高頻焊、等離子焊和激光焊等。幾種焊接方法各具特點(diǎn)，目前使用**多的是氬弧焊和高頻焊。下面，就幾類焊接工藝技術(shù)江蘇進(jìn)百洪為大家做個(gè)詳細(xì)地介紹。不銹鋼焊管工藝技術(shù)——?dú)寤『?</p> <p> 不銹鋼焊管要求熔深焊透，不含氧化物夾雜，熱影響區(qū)盡可能小，鎢極惰性氣體保護(hù)的氬弧焊具有較好的適應(yīng)性，焊接質(zhì)量高、焊透性能好，其產(chǎn)品在化工、核工業(yè)和食品等工業(yè)中得到廣泛應(yīng)用。 </p> <p> 焊接速度不高是氬弧焊的不足之處，為提高焊接速度，一般采用三電極焊炬的氬弧焊，焊接鋼管壁厚S≥2mm，焊接速度比單焊炬提高3-4倍，焊接質(zhì)量也得以改善。氬弧焊與等離子焊組合可以焊接更大壁厚的鋼管，此外，在氬氣中5-10%的氫氣，再采用高頻脈沖焊接電源，也可提高焊接速度。 </p> <p> <br /> </p> <p> <br />

關(guān)于在低溫狀態(tài)下，鐵素體不銹鋼管存在像碳素鋼那樣的低溫脆性，而奧氏體鋼則不存在。因此鐵素體或馬氏體不銹鋼產(chǎn)生低溫脆化而奧氏體系不銹鋼或鎳基合金不顯示低溫脆性。鐵素體不銹鋼管的SUS410（13Cr），SUS430（18Cr)等在低溫狀態(tài)下，顯示出沖擊值急劇下降。所以，在低溫狀態(tài)下使用時(shí)，有必要特別注意。作為改善鐵素體系列不銹鋼沖擊韌性的方法，可考慮進(jìn)行高純化工藝。借助于控制C，N等級水平，脆化溫度在-50℃到-100℃范圍內(nèi)進(jìn)行改善時(shí)，有可能將其用于與冷凍相關(guān)的工程。已將SUS430LX（18Cr-Ti，Nb-LC)和SUS436L（18Cr-Mo-Ti,Nb-LC)等應(yīng)用于冷凍器具的殼體。鐵素體不銹鋼因?yàn)槭求w心立方結(jié)構(gòu)，當(dāng)材料性能呈現(xiàn)出變?nèi)鯐r(shí)，尖銳的裂紋會(huì)迅速地?cái)U(kuò)展而造成脆性破壞。奧氏體系列不銹鋼因?yàn)槭敲嫘牧⒎浇Y(jié)構(gòu)而不會(huì)產(chǎn)生脆性破壞。奧術(shù)投入不銹鋼SUS304L（18Cr-9Ni-LC）和SUS316L（18Cr-12Ni-2Mo-LC)等顯示出在低溫狀態(tài)下仍具有優(yōu)越的沖擊特性。</p><p style="text-indent:25px"> 不銹鋼焊管開裂是什么原因？不銹鋼焊管原料含有多種金屬元素，如：鉻、鎳、碳、鐵等。正是由于這些金屬元素的存在，才使得不銹鋼管具有良好的延展性和耐蝕性。不銹鋼焊管材具有伸長率小、彈性大、硬化**高、從屈服到斷裂的塑性變形階段短等優(yōu)點(diǎn)，拉深變形后有時(shí)會(huì)出現(xiàn)拉深開裂，從凹模拉出時(shí)會(huì)立即發(fā)生開裂，深沖變形后有時(shí)會(huì)發(fā)生沖擊或振動(dòng)，深拉變形后會(huì)在貯存或使用一段時(shí)間后發(fā)生。那么，為什么不銹鋼焊管在拉深方面有缺點(diǎn)呢?開裂原因：奧氏體不銹鋼焊管的冷加工硬化**為0.34。奧氏體不銹鋼焊管是一種亞穩(wěn)定型，在變形過程中會(huì)發(fā)生相變并誘發(fā)馬氏體**，馬氏體**脆性大，易開裂，塑性變形過程中，隨著變形量的增加，誘發(fā)馬氏體**的含量越高，殘余應(yīng)力越大，加工過程中裂紋越容易發(fā)生。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。</p><div

310S不銹鋼管焊接時(shí)應(yīng)該注意什么？日常生活中我們經(jīng)常接觸到不銹鋼樓梯扶手、防盜窗、防盜門、還有不銹鋼椅子，可是它們是怎么從一根根310S不銹鋼管變成這些物品呢？焊接時(shí)有什么注意事項(xiàng)么？下面江蘇進(jìn)百洪為您簡單介紹下: </p> <p> 一、在采用垂直外特性的電源時(shí)，如果是直流電好采用正極性的，而且焊接310S不銹鋼管好連接負(fù)極。 </p> <p> 二、如果對于焊接的是比較薄的板材，使用310S不銹鋼管的焊接方式，具有焊縫成型美觀，焊接變形量小的特點(diǎn)。 </p> <p> <p> 三、在進(jìn)行310S不銹鋼管焊接的時(shí)候，其所保護(hù)的氣體是氮?dú)猓⒁馄浼兌?、焊接的電流、氮?dú)馑枰碾娏?、氮?dú)獾牧髁康取? </p> <p> 四、對于鎢絲極中所噴出的氣體長度，以4mm左右為準(zhǔn)，在一些角焊之后好以2mm為準(zhǔn)。 </p> <p> 五、在作業(yè)的時(shí)候?yàn)榱藴p少310S不銹鋼管焊接出現(xiàn)氣孔的可能性，所以焊接部位如過有鐵銹、油污等要清理干凈。 </p> <p> 六、在進(jìn)行310S不銹鋼管對接打底的時(shí)候，為減少底層焊道的背面被氧化的可能性，背面也需要實(shí)施氣體保護(hù)。 </p> <p> 七、為了保護(hù)310S不銹鋼管在焊接的時(shí)候，氮?dú)饽苈淙氲饺鄢禺?dāng)中，相關(guān)職業(yè)人員覺得鎢極中線與焊接處工件一般應(yīng)保持有一個(gè)傾斜度。 </p> <p> <br /> </p>
