指實(shí)心）的優(yōu)點(diǎn)組合而成，焊劑包在焊絲內(nèi)并藉**CO2氣體的保護(hù)可使焊接時(shí)產(chǎn)生較柔和且穩(wěn)定的電弧以及低飛濺為其特點(diǎn)。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(kuò)展了藥芯焊絲使用的領(lǐng)域。自保護(hù)藥芯焊絲，是在氣保護(hù)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(rèn)同于特定的用途上。兩者比較大的不同點(diǎn)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(yán)謹(jǐn)，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(xué)成份均需詳細(xì)核對(duì)以確保品質(zhì)。由于焊材內(nèi)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(jié)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(zhǎng)條逐段經(jīng)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(jīng)***的密封滾卷步驟，將焊劑緊緊的滾壓在管形焊絲內(nèi)卷成管形的焊絲再經(jīng)過一連串抽拉動(dòng)作成為***需要的絲徑，此抽拉的動(dòng)作也可以使填充的焊劑均勻的固定在焊絲皮材內(nèi)。制造/生產(chǎn)過程中如何不使焊絲內(nèi)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(chǎn)品質(zhì)的關(guān)鍵。</p><p> 另外線材表面亦需光滑平順且清潔否則將影響送絲的順暢及焊接電流的傳迅。焊絲包裝成卷或成桶以避免線材相互糾纏或折損，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(shí)斷面多為對(duì)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(shí)，絲材內(nèi)需較大的空間包容焊劑與合金元素?cái)嗝嫘螤顒t多成疊接或心形（LAP及HEARAPED）接頭。焊絲特點(diǎn)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(xué)成分與機(jī)械性之功能。生產(chǎn)效率上又有氣體保護(hù)金屬電弧焊及埋弧焊的特點(diǎn)。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(guó)產(chǎn)藥芯焊絲的品種和用量與日俱增。與實(shí)心焊絲相比藥芯焊絲有如下優(yōu)缺點(diǎn)。⑴優(yōu)點(diǎn)：1）對(duì)各種鋼材的焊接，適應(yīng)性強(qiáng)調(diào)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(xué)成分。2）工藝性能好，焊縫成形美觀采用氣渣聯(lián)合保護(hù)，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。?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。</p><div
