生產(chǎn)效率高在相同焊接電流下藥芯焊絲的電流密度大，熔化速度快，其熔敷率約為85%-90%，生產(chǎn)率比焊條電弧焊高約3-5倍。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，可以提高（改善）熔填金屬的強(qiáng)度、延性、硬度及韌性等。</p><p> 盡量選擇小電流焊接，因?yàn)樵陔娏魈髸r(shí)，易造成熔池翻滾，不僅飛濺大，成形也很差。6、焊接速度：對(duì)焊縫內(nèi)部與外觀的質(zhì)量都有重要影響。焊速過快會(huì)使氣體保護(hù)不好，出現(xiàn)氣孔等缺點(diǎn)，同時(shí)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(shí)，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(dāng)噴嘴與工件垂直時(shí)，飛濺會(huì)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(yùn)條方法：1.直線法，直線往復(fù)法。（適合小而窄的焊縫）。2.鋸齒形（適合寬焊縫），操作要點(diǎn)：在焊縫的兩邊稍作停頓，中間過度要**.月牙形運(yùn)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(diǎn)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）。絕大部分的藥芯焊絲均由一扁平金屬薄片長條逐段經(jīng)過滾卷成U型斷面。</p><div
