藥芯焊絲焊接時(shí)比CO2實(shí)芯焊絲的飛濺要小得多，下圖為藥芯焊絲與CO2實(shí)芯焊絲飛濺大小的比較。焊接質(zhì)量好一般CO2實(shí)芯焊絲只適合于低碳鋼或強(qiáng)度級(jí)別較低的低合金鋼的焊接，而藥芯焊絲則適用于各種材料的焊接，不僅包括各種結(jié)構(gòu)鋼，也包括不銹鋼等特殊材料。藥芯焊絲焊縫的低溫沖擊韌度比實(shí)芯焊絲有了很大的提高，可適用于各種重要結(jié)構(gòu)的焊接，而CO2實(shí)芯焊絲一般只用于0度以上工作的一般鋼結(jié)構(gòu)。綜合焊接成本：低藥芯焊絲相對(duì)價(jià)格較高，但其綜合生產(chǎn)成本比焊條電弧焊要低許多，與CO2實(shí)芯焊絲大體相當(dāng)。藥芯焊絲的型號(hào)及牌號(hào)按GB10045—88規(guī)怎定，藥芯焊絲***部分以英文字母“EF”表示藥芯焊絲代號(hào)，代號(hào)后面的***位數(shù)字表示主要適用的焊接位置：“0”表示用于平焊和橫焊，“1”表示用于全位置焊。代號(hào)后面的第二位數(shù)字或英文字母為分類(lèi)代號(hào)。第二部分在短橫線(xiàn)后用四位數(shù)字表示焊縫金屬的力學(xué)性能。如焊絲型號(hào)EF03-5042。實(shí)際生產(chǎn)中還經(jīng)常用牌號(hào)來(lái)表示藥芯焊絲的類(lèi)型。藥芯焊絲生產(chǎn)牌號(hào)用如下符號(hào)表示：首字母“Y”表示藥芯焊絲；第二位字母表示藥芯焊絲種類(lèi)，***、第二位數(shù)字表示焊絲特點(diǎn)；第三位數(shù)字表示溶渣類(lèi)型（或第三位以后之?dāng)?shù)字及元素符號(hào)表示焊縫金屬化學(xué)成分）。線(xiàn)材表面亦需光滑平順且清潔否則將影響送絲的順暢及焊接電流的傳迅。</p><div
