埋弧焊用不銹鋼焊絲化學成分及質量要求
有填充(chong)絲的(de)熔(rong)(rong)(rong)化(hua)焊(han)(han)(han)(han)(han)時，焊(han)(han)(han)(han)(han)縫的(de)化(hua)學成(cheng)(cheng)(cheng)分和(he)性(xing)能(neng)決定于焊(han)(han)(han)(han)(han)絲（焊(han)(han)(han)(han)(han)條的(de)焊(han)(han)(han)(han)(han)芯）、焊(han)(han)(han)(han)(han)劑（焊(han)(han)(han)(han)(han)條藥(yao)皮(pi)）和(he)被熔(rong)(rong)(rong)入的(de)母(mu)材以及它們各自所(suo)占的(de)比例。埋弧焊(han)(han)(han)(han)(han)時焊(han)(han)(han)(han)(han)接(jie)電流大，熔(rong)(rong)(rong)深大，母(mu)材金屬熔(rong)(rong)(rong)合比高，故母(mu)材金屬成(cheng)(cheng)(cheng)分對(dui)焊(han)(han)(han)(han)(han)縫成(cheng)(cheng)(cheng)分和(he)性(xing)能(neng)的(de)影響比焊(han)(han)(han)(han)(han)條電弧焊(han)(han)(han)(han)(han)時更(geng)大，同時焊(han)(han)(han)(han)(han)接(jie)參數也會(hui)對(dui)焊(han)(han)(han)(han)(han)縫化(hua)學成(cheng)(cheng)(cheng)分和(he)性(xing)能(neng)帶來一定...
