鍍鋅圓管的焊接注意事項(xiàng)：焊接前必須拋光焊縫。焊接位置的鍍鋅層必須打磨掉，否則會(huì)出現(xiàn)氣泡、砂眼、假焊等。會(huì)發(fā)生。它還會(huì)使焊縫變脆并降低剛性。 </p> <p> 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(diǎn)為419℃，沸點(diǎn)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(diǎn)鋅將形成“液態(tài)金屬脆化”。 </p> <p> 同時(shí)，鋅和鐵會(huì)在金屬間形成脆性化合物。這些脆性相會(huì)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(huì)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(diǎn)，約高于1800℃。如果焊接過程中參數(shù)太小，會(huì)導(dǎo)致氧化鋅渣夾雜。因?yàn)殇\變成了脫氧劑。產(chǎn)生Feo-mno或feo-mno-sio2低熔點(diǎn)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(duì)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。昆明質(zhì)量鍍鋅圓管價(jià)錢焊接鍍鋅圓管的前提就是要打磨。</p><div

style="text-indent:25px">常說的鍍鋅圓管，煤氣、暖氣用的那種鐵管也是鍍鋅圓管，鍍鋅圓管作為水管，使用幾年后，管內(nèi)產(chǎn)生大量銹垢，流出的黃水不僅污染潔具，而且夾雜著不光滑內(nèi)壁滋生的細(xì)菌，銹蝕造成水中重金屬含量過高，嚴(yán)重危害人體的健康。先利用溶劑清洗鋼材表面，把表面的有機(jī)物去除，然后使用工具除銹（鋼絲刷）,去除松動(dòng)或傾斜的規(guī)模，鐵銹，焊渣等,使用酸洗的方式。鍍鋅分為熱鍍和冷鍍，熱鍍不易生銹，冷鍍較易生銹。鍍鋅圓管管口對(duì)接后出現(xiàn)兩支管口對(duì)接不嚴(yán)現(xiàn)象，導(dǎo)致焊口薄厚不均勻；以及鋼管由于本身原因或運(yùn)輸磕碰，造成管口橢圓，建議將鋼管管頭截掉一小段兒后再進(jìn)行加工。熱鍍鋅圓管是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層，從而使基體和鍍層二者相結(jié)合。熱鍍鋅圓管是先將鋼管進(jìn)行酸洗，為了去除鋼管表面的氧化鐵，酸洗后，通過氯化銨或氯化鋅水溶液或氯化銨和氯化鋅混合水溶液槽中進(jìn)行清洗，然后送入熱浸鍍槽中。熱鍍鋅具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。目前消防給水管道基本上是鍍鋅管，鍍鋅管外層涂有油漆，其實(shí)它們只是經(jīng)過鍍鋅圓管加工而成。</p><div

鍍鋅圓管的焊接過程控制：鍍鋅圓管焊接前的準(zhǔn)備與低碳鋼相同。應(yīng)注意槽的尺寸和附近的鍍鋅層應(yīng)小心處理。為了滲透，槽的尺寸應(yīng)適當(dāng)，一般60-65度，留有一定的間隙，一般1.5-2.5 mm。為了減少鋅對(duì)焊縫的滲透，在焊接前，可將槽內(nèi)的鍍鋅層去除，然后焊接。 </p> <p> 在實(shí)際監(jiān)理工作中，采用集中開槽、無鈍邊技術(shù)和雙層焊接技術(shù)對(duì)集中開槽進(jìn)行控制，降低了不穿透的可能性。 </p> <p> 焊條應(yīng)根據(jù)鍍鋅管的基材選用。J422由于操作簡(jiǎn)單，是低碳鋼的常用選擇。 </p> <p> 焊接方式:多層焊縫第壹層焊接時(shí)，盡量使鋅層在焊縫外熔化汽化蒸發(fā)，可很大程度上減少焊縫中殘留的液態(tài)鋅。 </p> <p> 當(dāng)角焊縫焊接時(shí)，鋅層在第壹層熔化，蒸發(fā)蒸發(fā)，從焊縫中逸出。方法是將電極頭向前移動(dòng)5- 7mm左右，待鋅層融化回到原來位置后繼續(xù)焊接。 </p> <p> 短渣電極如J427用于交叉焊和立焊時(shí)，咬邊傾向很小;采用前后輸送桿技術(shù)，可獲得無缺陷焊接質(zhì)量。昆明鍍鋅圓管批發(fā)報(bào)價(jià)，云南鍍鋅圓管報(bào)價(jià)表，昆明鋼好物資供應(yīng)。昆明質(zhì)量鍍鋅圓管價(jià)錢</p><p
