style="text-indent:25px">鍍鋅圓管可以焊接嗎？應(yīng)注意什么？焊接鍍鋅圓管的前提就是要打磨。但是焊接部位的鍍鋅層必須打磨，否則會產(chǎn)生氣泡、沙眼、假焊等。它還會使焊縫脆性，降低剛性。鍍鋅鋼的焊接特性：鍍鋅鋼通常在低碳鋼的外面涂上一層鋅，鍍鋅層厚度通常為20um。鋅的熔點為419C，沸點為908C左右。在焊接過程中，鋅會熔化成液體，浮在熔池表面或焊縫根部。鋅在鐵中有很高的固溶性。液態(tài)鋅沿晶界對焊縫金屬進(jìn)行深度腐蝕，低熔點鋅會形成“液態(tài)金屬脆化”。同時，鋅和鐵可以形成金屬間脆性化合物。這些脆性相降低了焊縫金屬的塑性，在拉應(yīng)力作用下產(chǎn)生裂紋。如果角焊縫，特別是t形接頭的角焊縫，容易產(chǎn)生穿透性裂紋。鍍鋅鋼焊接時，坡口表面和邊緣的鋅層在電弧熱的作用下產(chǎn)生氧化、熔化、蒸發(fā)甚至蒸發(fā)白色粉塵和蒸汽，容易產(chǎn)生焊縫氣孔。氧化形成的氧化鋅熔點大于1800c，如果焊接參數(shù)過小，會引起氧化鋅夾渣，同時。因為鋅變成了脫氧劑。生產(chǎn)了低熔點氧化鐵爐渣。其次，由于鋅的蒸發(fā)，大量的白煙揮發(fā)，對人體有刺激和有害的影響。因此，焊接現(xiàn)場有必要對鍍鋅層進(jìn)行拋光。昆明鍍鋅圓管哪家便宜</p></p><br
