引弧不好，電弧不穩(wěn)，熔池淺。導(dǎo)電嘴-母材間距離過(guò)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(shì)：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(guò)大，焊平衡的作業(yè)姿勢(shì)。操作者姿勢(shì)及焊操作不好時(shí)，均得不到均勻的焊縫，因此，改變姿勢(shì)，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(kāi)閉焊開(kāi)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(kāi)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(lái)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(guò)程穩(wěn)定，飛濺小。上海鑄鐵焊條焊絲商家對(duì)各種鋼材的焊接，適應(yīng)性強(qiáng)

控制層間溫度對(duì)避免產(chǎn)生晶問(wèn)腐蝕及熱裂紋尤為重要，并可控制焊縫根部的氧化，因此焊接時(shí)應(yīng)盡量選用小線能量快速焊。層間溫度應(yīng)控制在50~60℃。焊接工藝參數(shù)焊接前將坡口內(nèi)外邊緣10~20mm處焊件表面的油污、水、銹等清理干凈，露出金屬光澤。焊接工藝參數(shù)的選擇，見(jiàn)表4所示。2、焊縫外觀檢驗(yàn)及性能試驗(yàn)焊縫外觀成形良好，尤其是焊縫背面成形美觀，無(wú)焊瘤、未熔合、未焊透等缺點(diǎn)。射線檢測(cè)按照J(rèn)B/T4730《承壓設(shè)備無(wú)損檢測(cè)》標(biāo)準(zhǔn)進(jìn)行，II級(jí)及以上為合格，經(jīng)評(píng)定為合格。力學(xué)性能試驗(yàn)按GB/T228和GB/T2653規(guī)定的試驗(yàn)方法，對(duì)焊接接頭試樣進(jìn)行了拉伸試驗(yàn)和彎曲試驗(yàn)，拉伸實(shí)驗(yàn)結(jié)果如表5所示，彎曲試驗(yàn)結(jié)果如表6所示。實(shí)驗(yàn)結(jié)果為合格。3、焊接操作要領(lǐng)不銹鋼藥芯焊絲是利用焊絲中間的藥粉熔化后，在熔敷金屬背面和正面形成熔渣進(jìn)行保護(hù)，所以根部焊接時(shí)與實(shí)芯焊絲焊接的操作方法、電弧擺動(dòng)頻率、填絲量有較大區(qū)別。（1）在焊接過(guò)程中，焊要做圓弧形擺動(dòng),其目的是使鐵水和熔渣加速分離，便于觀察熔池，同時(shí)也可增加母材坡口兩側(cè)的熱輸入量，防止出現(xiàn)單邊未熔合。在填充焊絲時(shí)，應(yīng)將焊絲送到熔池根部并向下輕壓一下，以保證根部熔透及根部?jī)?nèi)成形。。</p><p> co2氣保焊從不會(huì)到精通一、焊接開(kāi)始先打開(kāi)配電盤(pán)開(kāi)關(guān)，再打開(kāi)焊機(jī)電源開(kāi)關(guān)。（注意：再打開(kāi)電源開(kāi)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(kāi)儲(chǔ)氣瓶閥門(mén)。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(mén)，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(pán)的安裝選擇合適的焊絲直徑。向焊絲盤(pán)軸裝焊絲盤(pán)，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(guò)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(jiǎn)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(guò)經(jīng)驗(yàn)來(lái)掌握正常電弧的狀態(tài)。5.焊絲伸出長(zhǎng)度的影響：導(dǎo)電嘴-母材間距離過(guò)長(zhǎng)時(shí)，影響有：產(chǎn)生氣孔。用薄鋼帶卷成圓形或異形鋼管，內(nèi)填一定成分的藥粉，經(jīng)拉制成的有縫藥芯焊絲。</p><div
