焊接生產(chǎn)中大量采用焊條電弧焊。在工業(yè)發(fā)達國家，焊條的產(chǎn)量仍占焊材總產(chǎn)量的30%左右。在我國，這一比例為80%~90%左右。但從世界焊材發(fā)展的總趨勢看，隨著氣體保護焊工藝的***應(yīng)用和藥芯焊絲不斷崛起，手工焊條總的需求量會逐年下滑，今后的主要應(yīng)用對象是修配及某些特殊場合。在焊絲的生產(chǎn)上，埋弧焊焊絲在我國已經(jīng)應(yīng)用得非常***，埋弧焊用薄鋼帶也有應(yīng)用。近年來氣體保護焊和藥芯焊絲的應(yīng)用得到很大發(fā)展，使焊絲在消耗焊材中所占的比例日益增加，成為一種重要的焊接材料。焊絲的分類焊絲按其結(jié)構(gòu)可分為實芯焊絲和藥芯焊絲。實芯焊絲多為冷拔鋼絲；而藥芯焊絲則是由薄鋼帶縱向折迭并加入藥粉后，再行拉拔而成。實芯焊絲使用的歷史比較長，為目前主要使用的焊絲；藥絲焊絲的使用比起實芯焊絲來晚了許多，但由于其具有一系列優(yōu)點，在生產(chǎn)中應(yīng)用得越來越多。焊接用的焊絲按其保護方式又可分為兩大類：一類是焊接時焊絲只起填充金屬和導(dǎo)電的作用，施焊過程中要依靠焊劑保護或氣體保護，如埋弧焊、CO2氣體保護焊中使用的實芯焊絲和CO2氣體保護焊中使用的部分藥芯焊絲；另一類焊絲在焊接過程中不需要外加氣體或焊劑的保護。河南SKD-11焊條焊絲廠藥芯焊絲的制造過程控制非常嚴(yán)謹，由于熔填金屬來自鋼片皮材及焊劑所含的成份。</p><div

②MF742B堿***芯焊絲的特點是：粗熔滴過渡，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是：細熔滴射流過渡，熔渣覆蓋率低，藥芯成分由金屬合金和鐵粉組成，并含有電弧增強劑，熔敷效率高，再引弧性好。③比較實芯焊絲和藥芯焊絲可以看出，藥芯焊絲焊縫金屬Ni的含量比實芯焊絲高，因此焊縫的塑性和韌性更好，-60℃時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）實芯焊絲試驗依據(jù)ISO16834標(biāo)準(zhǔn)，并參照焊絲生產(chǎn)廠家提供的相關(guān)技術(shù)資料，進行了焊絲的試驗研究工作。兩種焊絲的化學(xué)成分檢測結(jié)果如表9所示。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，電弧電壓為24～30V，保護氣體為80%Ar+20%CO2混合氣體保護；焊接熱輸入～。多道焊時，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。</p><p>

焊接時聽到沙……沙的聲音，（小電流時聲音是滋滋聲）。焊接時焊機的電流表，電壓表的指針穩(wěn)定，擺動小。2.比較好規(guī)范的調(diào)整方法：根據(jù)焊件厚度，焊縫位置，選擇焊絲直徑，氣體流量，焊接電流。在試板上試焊，根據(jù)選擇的送絲速度，細心調(diào)整焊接電壓，比較好的浮動焊接電壓一般在1-2V之間。根據(jù)試板上焊縫成形情況，適當(dāng)調(diào)整送絲速度，焊接電壓，達到比較好焊接規(guī)范。在工件上正式焊接過程中，應(yīng)注意焊接回路，接觸電阻引起的電壓降，及時調(diào)整（微調(diào)）焊接電壓，確保焊接過程穩(wěn)定。3.焊接規(guī)范匹配不良的焊接現(xiàn)象及排除：當(dāng)焊絲端頭始終有滴狀金屬小球存在，且過度頻率偏低，此情況說明焊接電壓偏高，此時應(yīng)加快焊絲速度或降低焊接電壓。當(dāng)焊絲干伸偏短時能正常焊接，稍長就出現(xiàn)頂絲現(xiàn)象，說明焊接電壓偏低，此時應(yīng)通過降低送絲速度或升高焊接電壓。4、調(diào)試焊接參數(shù)時應(yīng)注意以下幾點：先把送絲速度調(diào)低點。再調(diào)焊接電壓，焊接電流應(yīng)根據(jù)焊接母材的厚度來控制。再調(diào)送絲速度，這時把送絲調(diào)到正好（電弧能夠把焊絲溶解，且溶解的很舒服）。聽聲音，看飛濺。如果溶解的很舒服，聲音是很平穩(wěn)的，不會乒乓作響，飛濺也少。5、在保證焊縫熔透（這里不是焊穿的意思）的情況下。河南優(yōu)瑞卡焊條焊絲價格</p><p
