引弧不好，電弧不穩(wěn)，熔池淺。導(dǎo)電嘴-母材間距離過短時：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保護焊一般采用向前行進法，這樣便于觀察焊接，焊縫形狀，氣體保護效果等。7.焊移動和作業(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，均得不到均勻的焊縫，因此，改變姿勢，計算電壓進行聯(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)閃滅進行處理。在焊縫還是塊狀時，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）進行焊接。五、日常檢修項目焊：***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。檢查送絲機的零件是否有損壞或松動，并及時***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。湖南卡博焊條焊絲供貨廠?二氧化碳?xì)怏w保護電弧焊（簡稱CO2焊）的保護氣體是二氧化碳（有時采用CO2+O2的混合氣體）。</p><div

⑸氣體形成劑氟石、石灰石等需添加在自保護藥芯焊絲中使燃燒產(chǎn)生保護氣體。⒊2焊渣的類別焊劑的成份決定焊材的焊接作業(yè)性與熔填金屬的機械性，焊劑成份中若以酸性為主，焊接后便生成酸性焊渣，同樣的以堿性（石灰質(zhì)）焊劑為主將產(chǎn)生堿性焊渣。酸性系統(tǒng)的焊材焊接性非常好，焊接過程中電弧平順穩(wěn)定，形態(tài)類似射流弧，飛濺量少，作業(yè)上廣為焊接人員所喜歡，熔填金屬機械性普通但可達AWS規(guī)范的要求。焊劑為堿性系統(tǒng)的焊材可使熔填金屬獲得非常優(yōu)良的延性與韌性，但作業(yè)性遠(yuǎn)較酸性系為差。熔滴的過渡多以球滴過渡為主，飛濺較多。低合金鋼焊材的焊劑系統(tǒng)的開發(fā)融合了酸性系的作業(yè)性與堿性系的優(yōu)良機械性。焊絲電火花類編輯電火花放電涂層冷焊機**焊絲，應(yīng)用于在常溫狀態(tài)下進行堆焊或焊接時用，焊補一秒后特點是焊絲溫度不超過40攝氏度，持續(xù)焊不超高80攝氏度。主要用于一些不耐熱的零件修復(fù)，焊補時，溫度一般控制在40攝氏度左右，壁厚在，比較高不高于一百攝氏度。焊絲焊補時熱影響區(qū)非常小，不會產(chǎn)生內(nèi)應(yīng)力。非常適合鑄造件缺點，零件表面拉傷、磨損，模具缺點的修復(fù)。焊絲溫度為什么這么低，因為該焊絲熔化時是微熔狀態(tài)，在與工件接觸時。</p><p> 藥芯焊絲焊接時比CO2實芯焊絲的飛濺要小得多，下圖為藥芯焊絲與CO2實芯焊絲飛濺大小的比較。焊接質(zhì)量好一般CO2實芯焊絲只適合于低碳鋼或強度級別較低的低合金鋼的焊接，而藥芯焊絲則適用于各種材料的焊接，不僅包括各種結(jié)構(gòu)鋼，也包括不銹鋼等特殊材料。藥芯焊絲焊縫的低溫沖擊韌度比實芯焊絲有了很大的提高，可適用于各種重要結(jié)構(gòu)的焊接，而CO2實芯焊絲一般只用于0度以上工作的一般鋼結(jié)構(gòu)。綜合焊接成本：低藥芯焊絲相對價格較高，但其綜合生產(chǎn)成本比焊條電弧焊要低許多，與CO2實芯焊絲大體相當(dāng)。藥芯焊絲的型號及牌號按GB10045—88規(guī)怎定，藥芯焊絲***部分以英文字母“EF”表示藥芯焊絲代號，代號后面的***位數(shù)字表示主要適用的焊接位置：“0”表示用于平焊和橫焊，“1”表示用于全位置焊。代號后面的第二位數(shù)字或英文字母為分類代號。第二部分在短橫線后用四位數(shù)字表示焊縫金屬的力學(xué)性能。如焊絲型號EF03-5042。實際生產(chǎn)中還經(jīng)常用牌號來表示藥芯焊絲的類型。藥芯焊絲生產(chǎn)牌號用如下符號表示：首字母“Y”表示藥芯焊絲；第二位字母表示藥芯焊絲種類，***、第二位數(shù)字表示焊絲特點；第三位數(shù)字表示溶渣類型（或第三位以后之?dāng)?shù)字及元素符號表示焊縫金屬化學(xué)成分）。?熔滴的過渡多以球滴過渡為主，飛濺較多。</p><div
