北京金威 E347L-16不銹鋼焊條 E347L-16電焊條不銹鋼焊條焊接時(shí)，要特別注意所選用焊條的含碳量不要超過母材的含碳量。從焊接工藝性能考慮，近年來，鈦鈣皮焊條受歡迎，被大量使用；鈦鈣型藥皮焊條不僅焊接工藝性能好，而且可以進(jìn)行全位置焊接，是不銹鋼焊條常用的藥皮類型之一；堿皮的不銹鋼焊條很少應(yīng)用在奧氏體不銹鋼焊接上，只是在馬氏體不銹鋼或剛度很大的焊接結(jié)構(gòu)上為了解決冷裂紋才采用。為了提高電弧的穩(wěn)定性，一般多采用電離電位較低的堿金屬以及堿金屬的氧化物作為穩(wěn)弧劑。對(duì)耐蝕不銹鋼的焊接，應(yīng)該根據(jù)腐蝕介質(zhì)的工作溫度來選擇焊條，對(duì)于焊接在常溫下工作并且腐蝕介質(zhì)的腐蝕性不強(qiáng)的焊件，可以采用不含Nb或Ti的不銹鋼焊條焊接；對(duì)于工作在腐蝕介質(zhì)是稀硫酸或鹽酸液體中的焊接結(jié)構(gòu)，焊接時(shí)常選用含Mo或含Mo和cu的不銹鋼焊條焊接；當(dāng)結(jié)構(gòu)工作在300℃以上，并且介質(zhì)的腐蝕性很強(qiáng)時(shí)，應(yīng)該選用含Nb或Ti元素或者是碳的不銹鋼焊條焊接。
