4）可用較大焊接電流進(jìn)行全位置焊接。⑵缺點(diǎn)1）焊絲制造過(guò)程復(fù)雜2）焊接時(shí)，送絲較實(shí)心焊絲困難3）焊絲外表容易銹蝕，粉劑易吸潮，因此對(duì)藥芯焊絲保存一管理的要求更為嚴(yán)格焊絲焊劑功能編輯與被覆焊條相同，藥芯焊絲的制造商對(duì)焊劑成份均為其特有的配方，隨著焊材適用的功能不同，焊劑成份組成亦各不同。焊劑成份的基本功能略述如下：⑴除氧劑與除氮?jiǎng)┯捎诘c氧可使焊道金屬造成氣孔或脆化，焊劑中必須添加錳與硅等除氧劑，至于自保護(hù)藥芯焊絲，焊劑中另需添加AL為除氮?jiǎng)?。以上添加除氧劑及除氮?jiǎng)┠康木谟趦艋厶罱饘?。⑵焊渣形成劑鈣、鉀、鈉或硅等均為焊渣形成劑，添加在焊劑中可以有效保護(hù)熔池不受大氣污染，焊渣可使焊道具較佳的外觀而且快速冷卻后又可以支撐全姿勢(shì)焊接時(shí)的熔池。焊渣的覆蓋更可緩和熔填金屬冷卻速率，此功能對(duì)低合金鋼的焊接尤其重要。⑶電弧穩(wěn)定劑鈉及鉀可以使電弧保持柔和順暢而且降低飛濺。⑷合金元素鉬、鉻、碳、錳、鎳及釩等合金元素的添加，河南特種焊條訂購(gòu)，可以提高（改善）熔填金屬的強(qiáng)度、延性、硬度及韌性等。⑸氣體形成劑氟石、石灰石等需添加在自保護(hù)藥芯焊絲中使燃燒產(chǎn)生保護(hù)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(jī)械性。酸性焊條焊接工藝性好，河南特種焊條訂購(gòu)，電弧穩(wěn)定，可交，河南特種焊條訂購(gòu)、直流兩用，飛濺小、熔渣流動(dòng)性和脫渣性好。河南特種焊條訂購(gòu)</p><div

不能用一般氬弧焊的連續(xù)送絲手法來(lái)進(jìn)行焊接，如果一次熔化的焊絲過(guò)多，涂層熔化的也多，熔渣和熔池的鐵液就更難分清，易在背面產(chǎn)生夾渣、未熔合、咬邊及未焊透等缺點(diǎn)。進(jìn)口焊絲除可以采用上述國(guó)產(chǎn)焊絲的斷續(xù)送絲手法外，由于進(jìn)口的焊絲熔渣和鐵液流動(dòng)性較好，也可以采用連續(xù)送絲的手法焊接，但不同于一般氬弧焊連續(xù)送絲方法的是連續(xù)送絲也是送到電弧前面由焊絲自然熔化后流入熔池，而不能把焊絲直接送到熔池里面與熔池直接接觸，否則背面容易出現(xiàn)未熔化的焊絲頭。這種連續(xù)送絲手法焊接速度快，特別適合薄壁管的焊接。（4）運(yùn)弧手法國(guó)產(chǎn)的涂層焊絲焊接時(shí)電弧左右擺動(dòng)幅度要小，控制熔池的熔渣不會(huì)很快凝固。焊絲藥皮的凝固點(diǎn)比母材高，藥皮首先凝固，包住熔池中的鐵液，使鐵液不易流動(dòng)，同時(shí)對(duì)鐵液進(jìn)行保護(hù)。如果擺動(dòng)幅度過(guò)大，電弧運(yùn)動(dòng)到坡口一側(cè)時(shí)，另一側(cè)熔渣就會(huì)凝固，電弧回來(lái)后短時(shí)間內(nèi)已經(jīng)凝固的熔渣不會(huì)很快熔化，而熔化的焊絲鐵液在凝固熔渣的阻礙下不能充分及時(shí)熔化坡口邊緣，就容易形成背面熔合不良和夾渣、咬邊缺點(diǎn)。因此在電弧左右擺動(dòng)時(shí)，擺動(dòng)幅度不要太寬，電弧能熔化坡口邊緣就行。電弧運(yùn)動(dòng)到右邊時(shí)，加一滴焊絲，再運(yùn)動(dòng)到左邊時(shí)加一滴焊絲。河南特種焊條訂購(gòu)焊條由焊芯及藥皮兩部分構(gòu)成。其種類不同，焊芯也不同。</p><div
