藥芯焊絲的截面形狀多種多樣，下圖各種藥芯焊絲的截面形狀。藥芯焊絲**簡(jiǎn)單的截面形狀是“O”形，通常又稱為管狀焊絲。這種焊絲由于芯部粉劑不導(dǎo)電，電弧容易沿四周的鋼皮旋轉(zhuǎn)，使得電弧穩(wěn)定性差。因此“0”形只用于制造細(xì)徑藥芯焊絲。異形焊絲因鋼皮在整個(gè)截面上分布比較均勻，所以電弧燃燒穩(wěn)定，焊絲熔化均勻，冶金反應(yīng)進(jìn)行得比較充分，適合于制造直徑。藥芯焊絲的優(yōu)點(diǎn)生產(chǎn)效率高藥芯焊絲可進(jìn)行連續(xù)的自動(dòng)化和半自動(dòng)化生產(chǎn)，與焊條相比，**節(jié)約了更換焊條、引弧和收弧等輔助工序的時(shí)間。同時(shí)它的焊接飛濺小，不易堵塞焊嘴，所以比CO2實(shí)芯焊絲更適于機(jī)器人焊接。熔敷速度快，飛濺小：熔敷速度是指熔焊過程中，單位時(shí)間內(nèi)熔敷在焊件上的金屬量。藥芯焊絲之所以比焊條熔敷速度快，主要是因?yàn)樗梢允褂酶蟮暮附与娏?；同時(shí)，藥芯焊絲中只含質(zhì)量分?jǐn)?shù)為15%~20%左右的藥粉，而焊條的涂料藥皮質(zhì)量分?jǐn)?shù)占25%以上，因此電能可以更有效地用來熔化焊絲的金屬部分。與CO2實(shí)芯焊絲相比，由于其電流集中于外表鋼皮，電流密度大，所產(chǎn)生的電阻熱更大；此外，飛濺小，所熔化金屬可以更有效地進(jìn)入熔池，因而藥芯焊絲甚至比CO2實(shí)芯焊絲的熔敷速度還要快。?低合金鋼焊材的焊劑系統(tǒng)的開發(fā)融合了酸性系的作業(yè)性與堿性系的優(yōu)良機(jī)械性。</p><div
