裂紋和氣孔。裂紋的出現(xiàn)頻率很高，一般裂紋分為熱裂紋和冷裂紋兩種。由于液體金屬在凝固過(guò)程中或略低于固相線溫度下，產(chǎn)生沿晶間邊界的、斷口上就會(huì)形成具有氧化色的熱裂紋。在固態(tài)時(shí)發(fā)生相變，或有擴(kuò)散氫存在，以及冷卻時(shí)在過(guò)大的焊接收縮應(yīng)力作用下，就會(huì)生成的具有穿晶性質(zhì)的、斷口發(fā)亮、沒(méi)有氧化色的冷裂紋。如果在使用焊絲時(shí)不合乎標(biāo)準(zhǔn)，焊接時(shí)高溫停留時(shí)間過(guò)長(zhǎng)，造成氧化、過(guò)熱和晶粒度過(guò)度長(zhǎng)大，材料本身雜質(zhì)較多，或材料本身易淬硬時(shí)均易產(chǎn)生裂紋。而在焊件、焊絲表面有油污，無(wú)錫2205不銹鋼價(jià)格、氧化皮、鐵銹等情況，或在潮濕環(huán)境中進(jìn)行焊接，或者氬氣純度低，或氬氣保護(hù)氣不佳以及熔池高溫氧化、飛濺等情況下都容易產(chǎn)生氣孔。不銹鋼焊管的焊接要求操作人員要詳細(xì)了解不同種類(lèi)的不銹鋼的特性，無(wú)錫2205不銹鋼價(jià)格，此外，也要熟練掌握不銹鋼焊接技術(shù)的具體方法，無(wú)錫2205不銹鋼價(jià)格，因此，生產(chǎn)廠家也要進(jìn)一步加強(qiáng)操作人員的技術(shù)培訓(xùn)。

不銹鋼焊管貯運(yùn)或再加工過(guò)程中表面受到污損以后往往需要再次鈍化，除合理選擇鈍化液化學(xué)成分以外，必須嚴(yán)格控制浸泡時(shí)間，防止過(guò)度酸洗出現(xiàn)霜凍狀毛面、甚至孔蝕。一般來(lái)講，30min就應(yīng)足夠，數(shù)十小時(shí)、甚至數(shù)日的長(zhǎng)時(shí)間浸泡在酸洗或鈍化液中是不恰當(dāng)?shù)摹?硝酸和氫氟酸混合液只適合用于固溶態(tài)奧氏體或退火態(tài)鐵素體不銹鋼焊管除氧化皮酸洗。 20%~50~硝酸或4%~10~檸檬酸液都可有效洗凈除熱加工氧化皮以外的表面沾污而形成有效的鈍化皮膜。電解拋光則是適用生產(chǎn)生化工程、半導(dǎo)體工業(yè)所需超凈表面不銹鋼焊管的高逛街鈍態(tài)表面的特殊方法。值得有條件的不銹鋼焊管制造廠或用戶有選擇地進(jìn)行探索和應(yīng)用。酸洗、鈍化液使用過(guò)程中會(huì)造成鐵離子濃度增加、酸度降低，從而促進(jìn)陰云狀（閃耀狀表面侵蝕）和孔蝕的提早出現(xiàn)。因此，應(yīng)注意酸洗鈍化液反復(fù)使用中的除污泥及酸液的添加更新。普通機(jī)械磨削拋光難以徹底清楚磨屑，只適用于焊態(tài)供貨的有敏化傾向不銹鋼焊管及結(jié)構(gòu)裝飾應(yīng)用，要求較高時(shí)應(yīng)在拋磨后再經(jīng)化學(xué)鈍化處理。
