②MF742B堿***芯焊絲的特點(diǎn)是：粗熔滴過(guò)渡，焊道略凸，煙塵較大，熔渣由氟化物和堿土金屬氧化物組成，焊縫金屬具有較高的沖擊韌性和抗裂紋能力。MF742M金屬粉末型藥芯焊絲的特點(diǎn)是：細(xì)熔滴射流過(guò)渡，熔渣覆蓋率低，藥芯成分由金屬合金和鐵粉組成，并含有電弧增強(qiáng)劑，熔敷效率高，再引弧性好。③比較實(shí)芯焊絲和藥芯焊絲可以看出，藥芯焊絲焊縫金屬Ni的含量比實(shí)芯焊絲高，因此焊縫的塑性和韌性更好，-60℃時(shí)仍有較高的沖擊韌性。（1）焊接試板：某鋼廠生產(chǎn)的Q960E調(diào)質(zhì)鋼板，板厚20mm。其化學(xué)成分及力學(xué)性能如表7、表8所示。（2）焊接材料的選擇實(shí)芯焊絲：選用奧林康（OERLIKON）公司的Mn4Ni2CrMo，φ（ESAB）公司的okAristRod89，φ；藥芯焊絲：選用斯泰因（STEINMEGAFIL）公司的MF745B，φ1100M，φ。（3）實(shí)芯焊絲試驗(yàn)依據(jù)ISO16834標(biāo)準(zhǔn)，山東鑄鐵拉延焊條焊絲廠家，并參照焊絲生產(chǎn)廠家提供的相關(guān)技術(shù)資料，進(jìn)行了焊絲的試驗(yàn)研究工作。兩種焊絲的化學(xué)成分檢測(cè)結(jié)果如表9所示，山東鑄鐵拉延焊條焊絲廠家。焊接工藝：預(yù)熱溫度為150℃，道間溫度為150～170℃；焊接電流為240～280A，山東鑄鐵拉延焊條焊絲廠家，電弧電壓為24～30V，保護(hù)氣體為80%Ar+20%CO2混合氣體保護(hù)；焊接熱輸入～。多道焊時(shí)，先焊坡口兩側(cè)的焊縫，再焊中間的焊縫。焊后用石棉布覆蓋。含有造渣、造氣和穩(wěn)弧成分的藥芯焊絲焊接時(shí)不需要保護(hù)氣體，稱(chēng)自保護(hù)藥芯焊絲。山東鑄鐵拉延焊條焊絲廠家</p><div

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）。湖南日亞焊條焊絲批發(fā)焊絲是作為填充金屬或同時(shí)作為導(dǎo)電用的金屬絲焊接材料。</p><div
