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(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），江蘇優(yōu)瑞卡焊條焊絲工廠。聽聲音，看飛濺。如果溶解的很舒服，聲音是很平穩(wěn)的，江蘇優(yōu)瑞卡焊條焊絲工廠，不會乒乓作響，江蘇優(yōu)瑞卡焊條焊絲工廠，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。打開焊絲包裝應(yīng)盡快將其全部用完（要求在一周以內(nèi)），一旦焊絲直接暴露在空氣中，其防銹時間將**縮短。江蘇優(yōu)瑞卡焊條焊絲工廠</p><div

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(yīng)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(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。選擇合適的導電嘴，并擰緊。四、焊操作基礎(chǔ)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。山東鑄鐵拉延焊條焊絲供應(yīng)商?焊絲溫度不會持續(xù)上升至其整段發(fā)紅，抗紅能力***。</p><div

高強鋼用實芯焊絲與藥芯焊絲熔敷金屬工藝性試驗對比研究通過具體的焊接試驗，分析總結(jié)出700MPa、900MPa不同級別實芯焊絲與藥芯焊絲各自的焊接工藝特點，為公司焊材的選用提供技術(shù)支持。關(guān)鍵詞：調(diào)質(zhì)鋼；焊接熱輸入；實芯焊絲；藥芯焊絲一、概述隨著工程機械產(chǎn)品輕量化、大型化的發(fā)展，低合金高強鋼的應(yīng)用領(lǐng)域越來越多。我公司在履帶式起重機、全地面起重機、礦用挖掘機等工程機械中已大量使用低合金高強鋼。由于低合金高強鋼的焊接工藝在以前沒有相關(guān)的資料積累，如何在現(xiàn)有的條件下，解決低合金高強鋼的焊接問題，成為當前**首要的攻關(guān)內(nèi)容。因此，本文通過對高強鋼用實芯焊絲與藥芯焊絲進行焊接試驗對比研究，為公司產(chǎn)品制造提供技術(shù)支持，同時降低生產(chǎn)成本。二、焊接試驗針對高強鋼母材類型，選擇與之匹配的實芯焊絲和藥芯焊絲進行對比試驗。焊接試板坡口形式如附圖所示。試板坡口形式（1）焊接試板某鋼廠生產(chǎn)的Q690E調(diào)質(zhì)鋼，板厚20mm。其化學成分及力學性能如表1、表2所示。（2）焊接材料的選擇與試驗實芯焊絲：選用奧林康（OERLIKON）公司的Mn3Ni1CrMo，φ（ESAB）公司的okAristRod69，φ；藥芯焊絲：選用斯泰因（STEIN-MEGAFIL）公司的MF742B，φ742M，φ。。</p><p>
