指實心）的優(yōu)點組合而成，焊劑包在焊絲內(nèi)并藉**CO2氣體的保護可使焊接時產(chǎn)生較柔和且穩(wěn)定的電弧以及低飛濺為其特點。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**的擴展了藥芯焊絲使用的領(lǐng)域。自保護藥芯焊絲，是在氣保護藥芯焊絲問市不久，便被發(fā)展出來，而且也很快的被工業(yè)界廣為認同于特定的用途上。兩者比較大的不同點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謹，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)成份均需詳細核對以確保品質(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)過一連串抽拉動作成為***需要的絲徑，此抽拉的動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><div
