  3087無縫鋼管(guan)(guan)的(de)化學(xue)成分(fen)有碳C、硅Si、錳Mn、硫(liu)S、磷P、鉻(ge)Cr。磁(ci)(ci)(ci)偏(pian)吹的(de)形成是管(guan)(guan)金屬中(zhong)存在(zai)剩(sheng)磁(ci)(ci)(ci)的(de)結果。通常,將剩(sheng)磁(ci)(ci)(ci)分(fen)為感應磁(ci)(ci)(ci)性(xing)(xing)和工(gong)(gong)(gong)藝磁(ci)(ci)(ci)性(xing)(xing)兩種(zhong)。感應磁(ci)(ci)(ci)性(xing)(xing)常產生在(zai)工(gong)(gong)(gong)廠制管(guan)(guan)的(de)環節中(zhong),如(ru):金屬熔煉、采用(yong)(yong)(yong)電(dian)(dian)磁(ci)(ci)(ci)起(qi)重機進行(xing)裝卸(xie)、鋼管(guan)(guan)在(zai)強(qiang)磁(ci)(ci)(ci)場中(zhong)停置、用(yong)(yong)(yong)磁(ci)(ci)(ci)化法完(wan)成無損巡查、鋼管(guan)(guan)接近強(qiang)力供(gong)電(dian)(dian)線(xian)放置等等。工(gong)(gong)(gong)藝磁(ci)(ci)(ci)性(xing)(xing)常產生在(zai)進行(xing)裝配焊(han)接作(zuo)業及采用(yong)(yong)(yong)磁(ci)(ci)(ci)性(xing)(xing)夾持器(qi)、夾具與用(yong)(yong)(yong)直流電(dian)(dian)焊(han)接管(guan)(guan)道時,如(ru):長時間接觸與直流電(dian)(dian)源相連的(de)電(dian)(dian)導線(xian),導線(xian)裸(luo)露段(duan)或(huo)者電(dian)(dian)焊(han)鉗與管(guan)(guan)子的(de)短路等。

  焊接(jie)帶磁性鋼管時,經常(chang)會(hui)看到電(dian)弧(hu)引(yin)燃的破壞、在磁場(定(ding)義:傳遞(di)實物間磁力作用的場)中(zhong)電(dian)弧(hu)的偏離、液體金屬和渣熔(rong)融體從焊接(jie)熔(rong)池(chi)中(zhong)的濺出。

  為了穩定焊(han)接過程,改善焊(han)接接頭質(zhi)量(liang),被磁(ci)化了的鋼管在焊(han)接前(qian)要進(jin)行消(xiao)磁(ci)。
