4）可用較大焊接電流進行全位置焊接。⑵缺點1）焊絲制造過程復雜2）焊接時，送絲較實心焊絲困難3）焊絲外表容易銹蝕，粉劑易吸潮，因此對藥芯焊絲保存一管理的要求更為嚴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除氧劑與除氮劑由于氮與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，至于自保護藥芯焊絲，焊劑中另需添加AL為除氮劑。以上添加除氧劑及除氮劑目的均在于凈化熔填金屬。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的熔池。焊渣的覆蓋更可緩和熔填金屬冷卻速率，此功能對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***皮中含有大量的堿性造渣物（大理石、螢石等），并含有一定數(shù)量的脫氧劑和滲合金劑。湖南沒有硬度鑄鐵焊條供應商</p><p

通常成卷絲材均以塑膠套包封后并放置干燥劑使避免材料受潮，包封后的材料再放入硬紙盒內(nèi)送出。在母材較厚時斷面多為對接（BUTT）方式且焊劑量較少，絕大多數(shù)的碳鋼及低合金鋼，絲徑在，類如不銹鋼等高合金且絲徑較大時，絲材內(nèi)需較大的空間包容焊劑與合金元素斷面形狀則多成疊接或心形（LAP及HEARAPED）接頭。焊絲特點前已述及藥芯焊絲突顯了許多焊接方法的有利特性，例如焊劑部分扮演了與被覆焊條能改善熔填金屬化學成分與機械性之功能。生產(chǎn)效率上又有氣體保護金屬電弧焊及埋弧焊的特點。藥芯焊絲可用于碳鋼，低合金高張力鋼，**度淬火回火鋼，不銹鋼以及硬面耐磨鋼材等的焊接。藥芯焊絲是很有發(fā)展前途的新型焊接材料，國產(chǎn)藥芯焊絲的品種和用量與日俱增。與實心焊絲相比藥芯焊絲有如下優(yōu)缺點。⑴優(yōu)點：1）對各種鋼材的焊接，適應性強調整焊劑的成分和比例極為方便和容易，可以提供所要求的焊縫化學成分。2）工藝性能好，焊縫成形美觀采用氣渣聯(lián)合保護，獲得良好成形。加入穩(wěn)弧劑使電弧穩(wěn)定，熔滴過渡均勻。3）熔敷速度快。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。江蘇THW焊條批發(fā)</p><p
