co2氣保焊從不會(huì)到精通一、焊接開始先打開配電盤開關(guān)，再打開焊機(jī)電源開關(guān)。（注意：再打開電源開關(guān)時(shí)，應(yīng)側(cè)身操作，避免因電器短路造成燒傷等）。緩慢打開儲(chǔ)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(chǔ)氣瓶閥門，放出氣管內(nèi)殘留氣體。然后關(guān)閉電源。把設(shè)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(dǎo)電嘴，并擰緊。四、焊操作基礎(chǔ)1.引弧及焊接完成時(shí)的操作:因?yàn)橐〖昂附油瓿蓵r(shí)容易出現(xiàn)缺點(diǎn)，所以操作焊時(shí)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(shí)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(shí)，容易產(chǎn)生缺點(diǎn)（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(dǎo)電嘴距離噴嘴外緣5mm比較好。4.氣體保護(hù)效果不好的識(shí)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(shí)的熔池成沸騰狀，需經(jīng)過經(jīng)驗(yàn)來掌握正常電弧的狀態(tài)。5.焊絲伸出長度的影響：導(dǎo)電嘴-母材間距離過長時(shí)，影響有：產(chǎn)生氣孔。加入穩(wěn)弧劑使電弧穩(wěn)定，熔滴過渡均勻。江西卡博焊條焊絲工廠</p><p

焊接時(shí)聽到沙……沙的聲音，（小電流時(shí)聲音是滋滋聲）。焊接時(shí)焊機(jī)的電流表，電壓表的指針穩(wěn)定，擺動(dòng)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(xì)心調(diào)整焊接電壓，比較好的浮動(dòng)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(dá)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(shí)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(shí)應(yīng)加快焊絲速度或降低焊接電壓。當(dāng)焊絲干伸偏短時(shí)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(shí)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(shí)應(yīng)注意以下幾點(diǎn)：先把送絲速度調(diào)低點(diǎn)。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(shí)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(huì)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。江西卡博焊條焊絲工廠</p><p
