～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縫藥芯焊絲（見圖）。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)藥芯焊絲便已開始開發(fā)問市，但至1957年才開始廣為商業(yè)上使用。此種方法可說是取自埋弧焊與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> 如果持續(xù)時(shí)間過長(zhǎng)，就會(huì)出現(xiàn)焊絲嚴(yán)重發(fā)紅，焊點(diǎn)發(fā)黑現(xiàn)象。就算能焊，焊補(bǔ)的時(shí)候，容易出現(xiàn)氧化，掉渣，焊不高等現(xiàn)象.，并且影響其后續(xù)加工。焊絲CO2焊編輯二氧化碳?xì)怏w保護(hù)電弧焊（簡(jiǎn)稱CO2焊）的保護(hù)氣體是二氧化碳（有時(shí)采用CO2+O2的混合氣體）。由于二氧化碳?xì)怏w的0熱物理性能的特殊影響，使用常規(guī)焊接電源時(shí)，焊絲端頭熔化金屬不可能形成平衡的軸向自由過渡，通常需要采用短路和熔滴縮頸爆斷、因此，與MIG焊自由過渡相比，飛濺較多。但如采用質(zhì)量焊機(jī)，參數(shù)選擇合適，可以得到很穩(wěn)定的焊接過程，使飛濺降低到**小的程度。由于所用保護(hù)氣體價(jià)格低廉，采用短路過渡時(shí)焊縫成形良好，加上使用含脫氧劑的焊絲即可獲得無內(nèi)部缺點(diǎn)的高質(zhì)量焊接接頭。因此這種焊接方法目前已成為黑色金屬材料**重要焊接方法之一。CO2立焊雙面成形焊絲型號(hào)編輯常用的焊絲型號(hào)：常見的氣體保護(hù)藥芯焊絲有：LQ122、LQ172、LQ212、LQ337、LQ423、LQ439、LQ451、LQ537、LQ582、LQ585、LQ605、LQ621、LQ666、LQ707等。一般直徑）常見的自保護(hù)藥芯焊絲有：LZ409、LZ410、LZ411、LZ414N、LZ430、LZ570、LZ590、LZ601、LZ603、LZ606、LZ632、LZ641、LZ642、LZ643、LZ650等。?對(duì)受條件限制不能翻轉(zhuǎn)的焊件，應(yīng)選用適于全位置焊接的焊條。</p><div
