鍍鋅圓管焊接特性分析： </p> <p> 一般來說，鍍鋅圓管在低碳鋼外面涂有一層鋅，鍍鋅層一般為20um厚。鋅的熔點為419℃，沸點約為908℃。在焊接中，鋅熔化成液體，漂浮在熔池表面或焊縫根部。鋅在鐵中有很大的固體溶解度。液態(tài)鋅將沿著晶界腐蝕焊接金屬，低熔點鋅將形成“液態(tài)金屬脆化”。 </p> <p> 同時，鋅和鐵會在金屬間形成脆性化合物。這些脆性相會降低焊接金屬的塑性，并在拉伸應(yīng)力下導(dǎo)致裂紋。 </p> <p> 如果角焊縫是焊接的，尤其是丁字接頭角焊縫，有可能產(chǎn)生貫穿裂紋。鍍鋅圓管焊接過程中，坡口表面和邊緣的鋅層在電弧加熱的作用下會氧化、熔化、蒸發(fā)，甚至?xí)l(fā)出白煙和蒸汽，容易造成焊縫氣孔。 </p> <p> 氧化形成的氧化鋅具有高熔點，約高于1800℃。如果焊接過程中參數(shù)太小，會導(dǎo)致氧化鋅渣夾雜。因為鋅變成了脫氧劑。產(chǎn)生Feo-mno或feo-mno-sio2低熔點氧化物渣。其次，由于鋅的蒸發(fā)，大量的白煙和灰塵被排放出來，這對人體有刺激和有害的影響。因此，焊接位置的鍍鋅層必須打磨掉。昆明40鍍鋅圓管哪個廠家的好鍍鋅圓管批發(fā)，昆明鋼好物資供應(yīng)。</p><div

如何控制鍍鋅圓管的焊接過程？ </p> <p> 鍍鋅圓管焊接前的準(zhǔn)備與普通低碳鋼相同。必須小心處理凹槽尺寸和附近的鍍鋅層。為了達(dá)到滲透，溝槽尺寸應(yīng)適當(dāng)，一般為60 ~ 65，有一定間隙，一般為1.5 ~ 2.5毫米；為了減少鋅滲透到焊縫中，可以在焊接前去除凹槽中的鍍鋅層。 </p> <p> 在實際監(jiān)理工作中，集中控制采用集中倒角和無鈍邊。雙層焊接工藝降低了不完全穿透的可能性。 </p> <p> 電極應(yīng)根據(jù)鍍鋅管的基材選擇。一般來說，J422因其可操作性而普遍用于低碳鋼。 </p> <p> 焊接方法:在焊接第壹層多層焊接時，盡量熔化鋅層，使其汽化蒸發(fā)，從焊縫中逸出，這樣可以很大程度上減少焊縫中殘留的液態(tài)鋅。 </p> <p> 焊接角焊縫時，鋅層應(yīng)盡可能在第壹層熔化、蒸發(fā)和蒸發(fā)，以從焊縫中逸出。方法是將電極末端向前移動約5 ~ 7毫米。當(dāng)鋅層熔化時，應(yīng)返回到原始位置并繼續(xù)向前焊接。 </p> <p> 如果短熔渣電極，如J427，用于交叉焊接和垂直焊接，底切趨勢將非常小；如果采用前后帶材運輸技術(shù)，可以獲得無缺陷的焊接質(zhì)量。許多新的鋼結(jié)構(gòu)工程現(xiàn)在都直接使用鍍鋅圓管，這樣可以節(jié)省時間。它會持續(xù)更久。</p><div style="width:100%;text-align: center;"><img
