開(kāi)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(kāi)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(wèn)市不久，便被發(fā)展出來(lái)，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(guò)程控制非常嚴(yán)謹(jǐn)，由于熔填金屬來(lái)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(niǎo).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(guò)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(guò)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(guò)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(méi)有焊劑）是藥芯焊絲生產(chǎn)品質(zhì)的關(guān)鍵。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。</p><div

中間消除應(yīng)力熱處理對(duì)消除焊接殘余應(yīng)力具有積極作用，為保證堆焊層的耐蝕及抗裂性能，條件允許下應(yīng)盡量進(jìn)行中間消除應(yīng)力熱處理。（4）總結(jié)與應(yīng)用①各廠家309LMo及316L藥芯焊絲焊接工藝性能良好，無(wú)明顯差異，GT廠焊絲組合過(guò)渡層焊絲與面層焊絲配合優(yōu)良，可得到無(wú)論是化學(xué)成分還是鐵素體含量（圖示法及磁性儀法兩種檢測(cè)方法）均較穩(wěn)定的堆焊層組.織。②各廠家焊絲組合堆焊試樣按GB/T4334方法E法進(jìn)行晶間腐蝕試驗(yàn)通過(guò)，晶間腐蝕性能滿足標(biāo)準(zhǔn)技術(shù)要求。GT及DS焊絲堆焊層塑性良好，彎曲試驗(yàn)未出現(xiàn)彎裂現(xiàn)象，JQ焊絲堆焊層塑性相對(duì)略差，出現(xiàn)了彎裂現(xiàn)象。各廠家藥芯焊絲組合堆焊層硬度性能均滿足氣化爐相關(guān)技術(shù)要求。③各廠家藥芯焊絲堆焊組合中：GT公司藥芯焊絲綜合性能更為良好，可選擇其用于氣化爐不銹鋼藥芯焊絲氣保焊堆焊，已成功應(yīng)用于我公司多個(gè)氣化爐項(xiàng)目；DS公司藥芯焊絲堆焊層化學(xué)成分及鐵素體含量（按WRC計(jì)算FN偏高）均勻穩(wěn)定性有待提高，并需進(jìn)一步的驗(yàn)證；JQ公司藥芯焊絲鐵素體含量偏下限，且堆焊焊縫塑性較差，需提高和進(jìn)一步的驗(yàn)證。3.結(jié)語(yǔ)（1）堆焊316L藥芯焊絲時(shí)采用309LMo藥芯焊絲進(jìn)行過(guò)渡層焊接可起到很好緩沖母材稀釋影響的過(guò)渡作用。</p><div
