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?。喝鄯笏俣仁侵溉酆高^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。</p><p> 引弧不好，電弧不穩(wěn)，熔池淺。導(dǎo)電嘴-母材間距離過短時(shí)：噴嘴容易被飛濺物堵塞，看不清焊接線，熔深變深。6.焊角度：二氧化碳?xì)怏w保護(hù)焊一般采用向前行進(jìn)法，這樣便于觀察焊接，焊縫形狀，氣體保護(hù)效果等。7.焊移動(dòng)和作業(yè)姿勢：焊由送絲軟管，氣管，控制電纜等構(gòu)成，為不影響焊接效果，應(yīng)采用保證焊彎曲不要過大，焊平衡的作業(yè)姿勢。操作者姿勢及焊操作不好時(shí)，均得不到均勻的焊縫，因此，改變姿勢，計(jì)算電壓進(jìn)行聯(lián)系，以求得到均勻的焊縫。8.收弧處理：在弧坑部開閉焊開關(guān)2~3次，使電弧重復(fù)閃滅進(jìn)行處理。在焊縫還是塊狀時(shí)，每隔，開3次即可充分埋好火口。9.焊縫連接方法：在火口前方引弧后，等電弧穩(wěn)定下來再返回火口部（接點(diǎn)）進(jìn)行焊接。五、日常檢修項(xiàng)目焊：***噴嘴，導(dǎo)電嘴，連接桿等部件上的飛濺物。導(dǎo)電嘴的檢查-焊絲是否吻合，孔徑是否合適，連接是否牢固，導(dǎo)電嘴是否在噴嘴的中間位置。檢查送絲機(jī)的零件是否有損壞或松動(dòng)，并及時(shí)***送絲部位的灰塵及贓物。檢查氣路是否有漏氣現(xiàn)象。檢查焊及焊接一體線是否有破損，如有銅線破損應(yīng)立即用絕緣膠布包好。六、氣保焊機(jī)參數(shù)調(diào)整方法1.比較好焊接規(guī)范（電流，電壓參數(shù)）的主要特征焊縫成型好。焊接過程穩(wěn)定，飛濺小。工藝性能好，焊縫成形美觀采用氣渣聯(lián)合保護(hù)，獲得良好成形。</p><div
