**依靠焊絲自身的合金元素及高溫時的反應(yīng)來防止空氣中氧、氮等氣體的侵入，以及調(diào)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(nèi)已開始生產(chǎn)，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(shù)字表示熔敷金屬的比較低抗拉強度，短劃后面的數(shù)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(shù)字分開。舉例如下：氣體保護焊焊絲的直徑比較小，**小為。上海鑄鐵拉延焊條焊絲若外觀顏色匹配是重要指標時，選擇焊絲時必須考慮所形成焊縫組.織的成分及組.織。</p><div

在制冷行業(yè)使用得尤其多，比如銅鋁管的套接，鋁管與鋁管的套接。另外在變壓器行業(yè)的銅鋁導排的搭接，角接也應(yīng)用得特別多，如何讓連接的導電排能夠在高壓和高電流的環(huán)境下工作，焊層的致密性尤為重要。相關(guān)的焊接介紹：銅鋁焊絲AlCu-Q303的操作及性能說明AlCu-Q303如何實現(xiàn)制冷行業(yè)的銅鋁焊接方法二：WE53實心釬料，解決所有白色金屬類的焊接，但是鋁合金運用得多，尤其包括鋁合金及各種鑄鋁的焊接。說明：因為WE53是實心釬料，在焊接過程中無需使用任何焊粉和焊劑，并且焊接后的強度非常高，所以一般很得需要有一定的焊接強度要求，并且又對變形有特殊要求的產(chǎn)品的焊接非常合適。在母材的溫度達到400度的時候，用WE53像搽橡皮搽一樣搽拭焊接處成型，焊接到哪，哪就是成型焊縫。在汽修行業(yè)用的特別多的是水箱，中冷器根部的補焊，空調(diào)管的補焊，冰箱角度不好的管路補焊，厚薄交界處的補焊等。相關(guān)的焊接介紹：鋁水箱焊接視頻—低溫釬焊鋁水箱鋁焊接視頻—記WE53氣焊鋁簡易操作WE53精彩鋁焊視頻教學分解方法三：M51+M51-F，低溫銅鋁焊接。說明：屬于低溫釬焊銅鋁焊接，對于特別薄，甚至有一些夸張的薄的情況下，運用這種焊接時**合適不過了，但是現(xiàn)場經(jīng)驗證明。</p><p>

盡量選擇小電流焊接，因為在電流太大時，易造成熔池翻滾，不*飛濺大，成形也很差。6、焊接速度：對焊縫內(nèi)部與外觀的質(zhì)量都有重要影響。焊速過快會使氣體保護不好，出現(xiàn)氣孔等缺點，同時焊縫的冷卻速度相應(yīng)提高，因而降低了焊縫金屬的塑性的韌性。焊速過慢時，熔池變大，焊縫變寬，易因過熱造成焊縫金屬組.織粗大或燒穿。7、噴嘴與工件的角度：當噴嘴與工件垂直時，飛濺會很大，電弧不穩(wěn)。為避免這種情況的出現(xiàn)，可將噴嘴后傾10-15度（焊接位置不同，焊角度也不同），即可保證焊縫成形良好，焊接過程穩(wěn)定。8、運條方法：1.直線法，直線往復法。（適合小而窄的焊縫）。2.鋸齒形（適合寬焊縫），操作要點：在焊縫的兩邊稍作停頓，中間過度要**.月牙形運條法（同鋸齒形）。以下幾種不宜掌握，知道就可以，三角形（斜三角，正三角），圓圖形（斜圓圖，正圓圖），八字形。七、焊接手法及焊接缺點產(chǎn)生的原因1.平焊（以右手向左焊，焊縫成形好，容易觀察熔池成形情況。角度大約45度;以右手向右焊，焊縫成形差）。存取及搬運焊絲時小心不要弄破包裝，特別是內(nèi)包裝“熱收縮膜”。南京卡博焊條焊絲銷售</p><p
