引弧不好，電弧不穩(wěn)，熔池淺。導電嘴-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：二氧化碳氣體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，控制電纜等構成，為不影響焊接效果，應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，計算電壓進行聯系，以求得到均勻的焊縫。8.收弧處理：在弧坑部開閉焊開關2~3次，使電弧重復閃滅進行處理。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，導電嘴，連接桿等部件上的飛濺物。導電嘴的檢查-焊絲是否吻合，孔徑是否合適，連接是否牢固，導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象。檢查焊及焊接一體線是否有破損，如有銅線破損應立即用絕緣膠布包好。六、氣保焊機參數調整方法1.比較好焊接規(guī)范（電流，電壓參數）的主要特征焊縫成型好。焊接過程穩(wěn)定，飛濺小。南京卡博焊條焊絲供應商?焊絲溫度不會持續(xù)上升至其整段發(fā)紅，抗紅能力***。</p><div

指實心）的優(yōu)點組合而成，焊劑包在焊絲內并藉**CO2氣體的保護可使焊接時產生較柔和且穩(wěn)定的電弧以及低飛濺為其特點。開發(fā)之初只有大絲徑焊絲（—），用于重大工件的平焊與橫焊。直至1972年小絲徑焊絲開始發(fā)展才**的擴展了藥芯焊絲使用的領域。自保護藥芯焊絲，是在氣保護藥芯焊絲問市不久，便被發(fā)展出來，而且也很快的被工業(yè)界廣為認同于特定的用途上。兩者比較大的不同點在第二單元便已有所述明，本單元將做整體的探討。焊絲介紹藥芯焊絲的制造過程控制非常嚴謹，由于熔填金屬來自鋼片皮材及焊劑所含的成份，制造前尺寸與化學成份均需詳細核對以確保品質。由于焊材內部空間受到限制，焊劑顆粒的大小愈顯得重要，顆粒間形成類似鳥.巢般結合在一起，焊劑成份元素不均勻。絕大部分的藥芯焊絲均由一扁平金屬薄片長條逐段經過滾卷成U型斷面，粒狀焊劑填充于U型金屬槽中然后再經***的密封滾卷步驟，將焊劑緊緊的滾壓在管形焊絲內卷成管形的焊絲再經過一連串抽拉動作成為***需要的絲徑，此抽拉的動作也可以使填充的焊劑均勻的固定在焊絲皮材內。制造/生產過程中如何不使焊絲內因管制不良而造成部分線材形成中空（沒有焊劑）是藥芯焊絲生產品質的關鍵。</p><p> 控制層間溫度對避免產生晶問腐蝕及熱裂紋尤為重要，并可控制焊縫根部的氧化，因此焊接時應盡量選用小線能量快速焊。層間溫度應控制在50~60℃。焊接工藝參數焊接前將坡口內外邊緣10~20mm處焊件表面的油污、水、銹等清理干凈，露出金屬光澤。焊接工藝參數的選擇，見表4所示。2、焊縫外觀檢驗及性能試驗焊縫外觀成形良好，尤其是焊縫背面成形美觀，無焊瘤、未熔合、未焊透等缺點。射線檢測按照JB/T4730《承壓設備無損檢測》標準進行，II級及以上為合格，經評定為合格。力學性能試驗按GB/T228和GB/T2653規(guī)定的試驗方法，對焊接接頭試樣進行了拉伸試驗和彎曲試驗，拉伸實驗結果如表5所示，彎曲試驗結果如表6所示。實驗結果為合格。3、焊接操作要領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行保護，所以根部焊接時與實芯焊絲焊接的操作方法、電弧擺動頻率、填絲量有較大區(qū)別。（1）在焊接過程中，焊要做圓弧形擺動,其目的是使鐵水和熔渣加速分離，便于觀察熔池，同時也可增加母材坡口兩側的熱輸入量，防止出現單邊未熔合。在填充焊絲時，應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內成形。。?有些合金，如鈷鉻鎢合金，不能鍛、軋和拔絲，而用鑄造方法制成。</p><div

**依靠焊絲自身的合金元素及高溫時的反應來防止空氣中氧、氮等氣體的侵入，以及調整焊縫金屬成分，這類焊絲稱為自保護藥芯焊絲，是一種很有發(fā)展前途的新型焊絲。國內已開始生產，但使用尚不***。實芯焊絲實芯焊絲的分類：實芯焊絲分氣體保護焊用碳素鋼、低合金鋼焊絲（鋼絲），熔化焊用鋼絲，銅及銅合金焊絲，鋁及鋁合金焊絲，鎳及鎳合金焊絲等。氣體保護焊用焊絲（鋼絲）主要包括二氧化碳氣體保護焊、鎢極氣體保護焊和等離子弧焊的焊絲。熔化焊用鋼絲主鼕包括適用于埋弧焊和電渣焊、氣焊等用途的冷拉鋼絲。為了防止焊絲生銹，保持焊絲的光潔，焊絲表面一般都鍍有—層銅，這也是為什么焊絲表面顏色為黃紅色的原因。鍍銅焊絲不影響焊絲的使用性能。氣體保護焊焊絲：（GB/T8110—1995)本標準適用于碳素鋼、低合金鋼熔化極氣體保護焊用的實芯焊絲，推薦用于鎢極氣體保護電弧焊和等離子弧焊的填充焊絲。焊絲型號的表示方法為：ERXX-X。字母ER表示焊絲，ER后面的兩位數字表示熔敷金屬的比較低抗拉強度，短劃后面的數字或字母表示焊絲化學成分分類代號。如還附加其它化學成分時，直接用元素符號表示，并以短劃與前面數字分開。舉例如下：氣體保護焊焊絲的直徑比較小，**小為。自保護藥芯焊絲，是在氣保護藥芯焊絲問市不久，便被發(fā)展出來，也很快的被工業(yè)界廣為認同于特定的用途上。南京卡博焊條焊絲供應商</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，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)點生產效率高藥芯焊絲可進行連續(xù)的自動化和半自動化生產，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?。喝鄯笏俣仁侵溉酆高^程中，單位時間內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，藥芯焊絲中只含質量分數為15%~20%左右的藥粉，而焊條的涂料藥皮質量分數占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。上海高溫焊條焊絲批發(fā)</p><p
