不銹鋼精密管打底層的焊接，以往采用手工鎢極氬弧焊配以實(shí)芯焊絲施焊方式，管內(nèi)充Ar防止焊縫根部氧化，保證焊縫內(nèi)部質(zhì)量。但是管內(nèi)充Ar在現(xiàn)場(chǎng)施工難度大，設(shè)備、罐體聯(lián)頭和長(zhǎng)管道焊接時(shí)充Ar量大，特別是高空作業(yè)更不利于施工，且輔助用工多，很不經(jīng)濟(jì)。為解決這些問(wèn)題，保證焊縫質(zhì)量，在施工中，對(duì)打底層采用藥芯焊絲鎢極氬弧焊(TIG)，填充、蓋面采用氣體保護(hù)金屬極電弧焊(MAG)。打底焊接時(shí)，焊***角度、焊絲角度與碳鋼焊接基本相同。河南2205不銹鋼無(wú)縫焊管加工質(zhì)量控制是保證不銹鋼焊管質(zhì)量的必要途徑，而原料檢驗(yàn)則是不銹鋼焊管質(zhì)量控制中的首要，十分關(guān)鍵的一步。</p><div
