co2氣保焊從不會到精通一、焊接開始先打開配電盤開關(guān)，再打開焊機電源開關(guān)。（注意：再打開電源開關(guān)時，應側(cè)身操作，避免因電器短路造成燒傷等）。緩慢打開儲氣瓶閥門。調(diào)節(jié)合適的氣壓。調(diào)節(jié)合適的電流，電壓。二、焊接結(jié)束關(guān)閉儲氣瓶閥門，放出氣管內(nèi)殘留氣體。然后關(guān)閉電源。把設備整理好放回原處。三、焊絲盤的安裝選擇合適的焊絲直徑。向焊絲盤軸裝焊絲盤，并固定牢固。將焊絲插入焊絲插口處。用焊絲加壓手柄給焊絲施加合適的壓力。選擇合適的導電嘴，并擰緊。四、焊操作基礎1.引弧及焊接完成時的操作:因為引弧及焊接完成時容易出現(xiàn)缺點，所以操作焊時一定要遵守噴嘴-工件間距離及焊角度。在引弧前的間隔，受到焊絲接觸時的沖擊而回升，注意勿使焊因沖擊而回升。2.噴嘴-工件間距離：噴嘴-工件間距離過大時，容易產(chǎn)生缺點（氣孔，坑等）。一般情況下采用焊絲直徑的10倍距離左右（如焊絲，選用距離為10毫米左右）。3.導電嘴距離噴嘴外緣5mm比較好。4.氣體保護效果不好的識別：根據(jù)電弧聲音及熔池狀態(tài)等就可以很簡單地判斷正常電弧，異常電弧時的熔池成沸騰狀，需經(jīng)過經(jīng)驗來掌握正常電弧的狀態(tài)。5.焊絲伸出長度的影響：導電嘴-母材間距離過長時，影響有：產(chǎn)生氣孔。江蘇優(yōu)瑞卡焊條焊絲訂購藥芯焊絲是很有發(fā)展前途的新型焊接材料，國產(chǎn)藥芯焊絲的品種和用量與日俱增。</p><div

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，此時應加快焊絲速度或降低焊接電壓。當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。</p><p> 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”形只用于制造細徑藥芯焊絲。異形焊絲因鋼皮在整個截面上分布比較均勻，所以電弧燃燒穩(wěn)定，焊絲熔化均勻，冶金反應進行得比較充分，適合于制造直徑。藥芯焊絲的優(yōu)點生產(chǎn)效率高藥芯焊絲可進行連續(xù)的自動化和半自動化生產(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間。同時它的焊接飛濺小，不易堵塞焊嘴，所以比CO2實芯焊絲更適于機器人焊接。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，主要是因為它可以使用更大的焊接電流；同時，藥芯焊絲中只含質(zhì)量分數(shù)為15%~20%左右的藥粉，而焊條的涂料藥皮質(zhì)量分數(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入熔池，因而藥芯焊絲甚至比CO2實芯焊絲的熔敷速度還要快。藥芯焊絲的制造過程控制非常嚴謹，熔填金屬來自鋼片皮材及焊劑所含的成份。</p><div
