不能用一般氬弧焊的連續(xù)送絲手法來(lái)進(jìn)行焊接，如果一次熔化的焊絲過(guò)多，涂層熔化的也多，熔渣和熔池的鐵液就更難分清，易在背面產(chǎn)生夾渣、未熔合、咬邊及未焊透等缺點(diǎn)。進(jìn)口焊絲除可以采用上述國(guó)產(chǎn)焊絲的斷續(xù)送絲手法外，由于進(jìn)口的焊絲熔渣和鐵液流動(dòng)性較好，也可以采用連續(xù)送絲的手法焊接，但不同于一般氬弧焊連續(xù)送絲方法的是連續(xù)送絲也是送到電弧前面由焊絲自然熔化后流入熔池，而不能把焊絲直接送到熔池里面與熔池直接接觸，否則背面容易出現(xiàn)未熔化的焊絲頭。這種連續(xù)送絲手法焊接速度快，特別適合薄壁管的焊接。（4）運(yùn)弧手法國(guó)產(chǎn)的涂層焊絲焊接時(shí)電弧左右擺動(dòng)幅度要小，控制熔池的熔渣不會(huì)很快凝固。焊絲藥皮的凝固點(diǎn)比母材高，藥皮首先凝固，包住熔池中的鐵液，使鐵液不易流動(dòng)，同時(shí)對(duì)鐵液進(jìn)行保護(hù)。如果擺動(dòng)幅度過(guò)大，電弧運(yùn)動(dòng)到坡口一側(cè)時(shí)，另一側(cè)熔渣就會(huì)凝固，電弧回來(lái)后短時(shí)間內(nèi)已經(jīng)凝固的熔渣不會(huì)很快熔化，而熔化的焊絲鐵液在凝固熔渣的阻礙下不能充分及時(shí)熔化坡口邊緣，就容易形成背面熔合不良和夾渣、咬邊缺點(diǎn)。因此在電弧左右擺動(dòng)時(shí)，擺動(dòng)幅度不要太寬，電弧能熔化坡口邊緣就行。電弧運(yùn)動(dòng)到右邊時(shí)，加一滴焊絲，再運(yùn)動(dòng)到左邊時(shí)加一滴焊絲。安徽焊條訂購(gòu)在焊條前端藥皮有45°左右的倒角，這是為了便于引弧。</p><div

～HB～300適用于氮化后模具，零件表面修補(bǔ)。焊絲鑄造類有些合金，如鈷鉻鎢合金，不能鍛、軋和拔絲，而用鑄造方法制成。它主要用于工件表面的手工堆焊，以滿足如抗氧化、耐磨損和高溫下耐腐蝕等特殊性能要求。采用連續(xù)澆注和液態(tài)擠壓可制造出長(zhǎng)達(dá)數(shù)米的鈷鉻鎢焊絲，用于自動(dòng)填絲鎢極氣體保護(hù)電弧焊，以提高焊接效率和堆焊層質(zhì)量，同時(shí)還能改善勞動(dòng)條件。鑄鐵補(bǔ)焊有時(shí)也采用鑄造焊絲。焊絲藥芯類用薄鋼帶卷成圓形或異形鋼管，內(nèi)填一定成分的藥粉，經(jīng)拉制成的有縫藥芯焊絲，或用鋼管填滿藥粉拉制成的無(wú)縫藥芯焊絲（見(jiàn)圖）。用這種焊絲焊接熔敷效率高，對(duì)鋼材適應(yīng)性好，試制周期短，因而它的使用量和使用范圍不斷擴(kuò)大。這種焊絲主要用于二氧化碳?xì)怏w保護(hù)焊、埋弧焊和電渣焊。藥芯焊絲中的藥粉成分一般與焊條藥皮相似。含有造渣、造氣和穩(wěn)弧成分的藥芯焊絲焊接時(shí)不需要保護(hù)氣體，稱自保護(hù)藥芯焊絲，適用于大型焊接結(jié)構(gòu)工程的施工。早在1950年代初氣保護(hù)藥芯焊絲便已開(kāi)始開(kāi)發(fā)問(wèn)市，但至1957年才開(kāi)始廣為商業(yè)上使用。此種方法可說(shuō)是取自埋弧焊與CO2焊接。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)。</p><p>
