成份優(yōu)良材料內(nèi)部組.織均勻，硬度穩(wěn)定，而且耐磨性、韌性、耐高溫等...。特性皆比一般同等級之材料為佳。氮化零件焊補(bǔ)焊絲>～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)擠壓可制造出長達(dá)數(shù)米的鈷鉻鎢焊絲，用于自動填絲鎢極氣體保護(hù)電弧焊，以提高焊接效率和堆焊層質(zhì)量，同時還能改善勞動條件。鑄鐵補(bǔ)焊有時也采用鑄造焊絲。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。南京鑄鐵拉延焊條焊絲供貨廠進(jìn)入90年代,由于冶金、造船、石化等行業(yè)對藥芯焊絲需求的增加,國內(nèi)外藥芯焊絲產(chǎn)業(yè)已開始啟動。</p><div

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。在母材較厚時斷面多為對接（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，絲材內(nèi)需較大的空間包容焊劑與合金元素斷面形狀則多成疊接或心形（LAP及HEARAPED）接頭。焊絲特點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。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，國產(chǎn)藥芯焊絲的品種和用量與日俱增。與實心焊絲相比藥芯焊絲有如下優(yōu)缺點。⑴優(yōu)點：1）對各種鋼材的焊接，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。南京鑄鐵焊條焊絲</p><p
