鍍鋅鋼焊接前的準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。為了達到滲透，溝槽尺寸應(yīng)適當，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。當鋅層熔化時，應(yīng)返回到原始位置并繼續(xù)向前焊接。 </p> <p> <br /> 昆明Q355B熱鍍鋅管廠家直銷為了保證管道的暢通，所以要求鍍鋅管必須較強的耐腐性。</p><div style="width:100%;text-align:

粉塵：鍍鋅鋼管公司介紹，制作經(jīng)常是在有粉塵的場地進行，空氣中常帶有許多粉塵，它們不斷地落在設(shè)備表面。它們可以用水或堿性溶液去除掉。不過，有附著力的塵垢需要高壓水或蒸氣進行清理。 </p> <p> 劃痕：為了防止工藝潤滑劑或生成物和/或污物積留，必須對劃痕和其它粗糙表面進行機械清理(如干噴砂,磨料用玻璃珠)。 </p> <p> 銹斑：鍍鋅鋼管廠家分析，制作前或制作過程中有時會看到不銹鋼產(chǎn)品或設(shè)備上生銹，這說明表面受到嚴重污染。設(shè)備投入使用前必須把銹清理掉，徹底清理過的表面應(yīng)通過鐵試驗和/或水試驗進行檢驗。 </p> <p> 焊接引弧斑痕：焊工在金屬表面引弧時，會造成表面粗糙缺點。保護膜受損，留下潛在的腐蝕源。焊工應(yīng)在已經(jīng)焊好的焊道上或在焊縫接頭的側(cè)邊引弧。然后將引弧痕跡熔入焊縫中。緬甸熱鍍鋅管價格，云南貿(mào)軒商貿(mào)有限公司。昆明Q355B熱鍍鋅管廠家直銷</p><p
