藥芯焊絲的截面形狀多種多樣，下圖各種藥芯焊絲的截面形狀。藥芯焊絲**簡(jiǎn)單的截面形狀是“O”形，通常又稱為管狀焊絲。這種焊絲由于芯部粉劑不導(dǎo)電，電弧容易沿四周的鋼皮旋轉(zhuǎn)，使得電弧穩(wěn)定性差。因此“0”形只用于制造細(xì)徑藥芯焊絲。異形焊絲因鋼皮在整個(gè)截面上分布比較均勻，江蘇模具焊條焊絲商家，所以電弧燃燒穩(wěn)定，焊絲熔化均勻，冶金反應(yīng)進(jìn)行得比較充分，適合于制造直徑。藥芯焊絲的優(yōu)點(diǎn)生產(chǎn)效率高藥芯焊絲可進(jìn)行連續(xù)的自動(dòng)化和半自動(dòng)化生產(chǎn)，與焊條相比，**節(jié)約了更換焊條、引弧和收弧等輔助工序的時(shí)間。同時(shí)它的焊接飛濺小，不易堵塞焊嘴，所以比CO2實(shí)芯焊絲更適于機(jī)器人焊接。熔敷速度快，飛濺小：熔敷速度是指熔焊過程中，單位時(shí)間內(nèi)熔敷在焊件上的金屬量。藥芯焊絲之所以比焊條熔敷速度快，主要是因?yàn)樗梢允褂酶蟮暮附与娏?；同時(shí)，藥芯焊絲中只含質(zhì)量分?jǐn)?shù)為15%~20%左右的藥粉，而焊條的涂料藥皮質(zhì)量分?jǐn)?shù)占25%以上，因此電能可以更有效地用來熔化焊絲的金屬部分。與CO2實(shí)芯焊絲相比，由于其電流集中于外表鋼皮，電流密度大，所產(chǎn)生的電阻熱更大；此外，江蘇模具焊條焊絲商家，飛濺小，所熔化金屬可以更有效地進(jìn)入熔池，因而藥芯焊絲甚至比CO2實(shí)芯焊絲的熔敷速度還要快，江蘇模具焊條焊絲商家。?在相同焊接電流下藥芯焊絲的電流密度大，熔化速度快，其熔敷率約為85%-90%，生產(chǎn)率比焊條電弧焊高約3-5倍。江蘇模具焊條焊絲商家</p><div

盡量選擇小電流焊接，因?yàn)樵陔娏魈髸r(shí)，易造成熔池翻滾，不僅飛濺大，成形也很差。6、焊接速度：對(duì)焊縫內(nèi)部與外觀的質(zhì)量都有重要影響。焊速過快會(huì)使氣體保護(hù)不好，出現(xiàn)氣孔等缺點(diǎn)，同時(shí)焊縫的冷卻速度相應(yīng)提高，因而降低了焊縫金屬的塑性的韌性。焊速過慢時(shí)，熔池變大，焊縫變寬，易因過熱造成焊縫金屬組.織粗大或燒穿。7、噴嘴與工件的角度：當(dāng)噴嘴與工件垂直時(shí)，飛濺會(huì)很大，電弧不穩(wěn)。為避免這種情況的出現(xiàn)，可將噴嘴后傾10-15度（焊接位置不同，焊角度也不同），即可保證焊縫成形良好，焊接過程穩(wěn)定。8、運(yùn)條方法：1.直線法，直線往復(fù)法。（適合小而窄的焊縫）。2.鋸齒形（適合寬焊縫），操作要點(diǎn)：在焊縫的兩邊稍作停頓，中間過度要**.月牙形運(yùn)條法（同鋸齒形）。以下幾種不宜掌握，知道就可以，三角形（斜三角，正三角），圓圖形（斜圓圖，正圓圖），八字形。七、焊接手法及焊接缺點(diǎn)產(chǎn)生的原因1.平焊（以右手向左焊，焊縫成形好，容易觀察熔池成形情況。角度大約45度;以右手向右焊，焊縫成形差）。江蘇模具焊條焊絲商家我國(guó)在六、七十年代就有人進(jìn)行過藥芯焊絲的研究,但是工作時(shí)斷時(shí)續(xù),始終未能形成氣候。</p><div

***一位數(shù)字為“1”或“2”，分別表示氣體保護(hù)或自保護(hù),并以短劃“-”與前面部分分開。藥芯焊絲發(fā)展很快，很多的藥芯焊絲牌號(hào)目前還沒有相應(yīng)的國(guó)標(biāo)型號(hào)對(duì)應(yīng)。常用藥芯焊絲的選用下表為常用藥芯焊絲性能的介紹，供選用時(shí)參考。焊絲的使用焊絲一般以焊絲盤、焊絲卷及焊絲筒的形式供貨。焊絲表面必須光滑平整，如果焊絲生銹，必須用焊絲除銹機(jī)除去表面氧化皮才能使用。對(duì)同一型號(hào)的焊絲，當(dāng)使用Ar-O2為保護(hù)氣體焊接時(shí)，熔敷金屬的化學(xué)成分與焊絲的化學(xué)成分差別不大，但當(dāng)使用CO2為保護(hù)氣體焊接時(shí)，熔敷金屬中的Mn、Si和其它脫氧元素的含量會(huì)**減少，在選擇焊絲和保護(hù)氣體時(shí)應(yīng)予以注意。—般情況下，實(shí)芯焊絲和藥芯焊絲對(duì)水分的影響不敏感，不需做烘干處理。焊前，焊件應(yīng)做除油、除銹處理。焊絲購(gòu)貨后應(yīng)存放于**焊材庫(kù)（庫(kù)中相對(duì)濕度應(yīng)低于60%)，對(duì)于已經(jīng)打開包裝的未鍍銅焊絲或藥芯焊絲，如無**焊材庫(kù)，應(yīng)在半年內(nèi)使用。采用焊劑保護(hù)進(jìn)行焊接，使用前應(yīng)對(duì)焊劑做烘干處理；采用氣體保護(hù)進(jìn)行焊接，應(yīng)控制氣體中的含水量，焊接時(shí)風(fēng)速大于2m/s，應(yīng)停止焊接。</p><p> 鑄造是機(jī)械制造的基礎(chǔ)工藝技術(shù)，由于種種原因在生產(chǎn)過程中會(huì)存在缺點(diǎn)，廢品率較高。另外，在各種機(jī)械裝備中的鑄鐵件在使用過程中極易損壞。由于鑄鐵的焊接性差，焊后常有氣孔，易變形，易斷裂，易產(chǎn)生白口化和焊接裂紋，從而給鑄件的修復(fù)產(chǎn)生相當(dāng)?shù)碾y度。到目前為止，國(guó)際國(guó)內(nèi)對(duì)此尚沒有解決的理論及方法。C808鑄鐵常溫焊接焊絲，經(jīng)實(shí)踐證明能有效地解決了鑄鐵件在焊接過程中產(chǎn)生的上述問題，得到了用戶的一致好評(píng)。C808鑄鐵常溫焊接焊絲可從理論及工藝上解決以下幾個(gè)方面的問題：（1）白口問題C808鑄鐵常溫焊接焊絲，采用CO2保護(hù)半自動(dòng)焊接技術(shù)，電流密度大，焊后冷卻速度快，母材與焊絲熔合區(qū)硬化層從金相分析看，白口層分析是斷續(xù)的，厚度均〈。（按照國(guó)際慣例，白口層厚度如果〈1mm，對(duì)鑄件加工切削刀具無影響，基本可以忽略不計(jì)）。（2）焊接產(chǎn)生熱裂紋的問題∶通常對(duì)鑄鐵件的焊補(bǔ)，一般都要對(duì)所焊鑄鐵件進(jìn)行局部快速加熱，加熱過程中溫度不均是必然的，當(dāng)熱應(yīng)力大于被焊件鑄鐵抗拉強(qiáng)度時(shí)，就必然產(chǎn)生熱裂紋。在設(shè)計(jì)C808鑄鐵常溫焊接焊絲化學(xué)成分時(shí)，使用屈服極限比較低可<200MPa，比較高可達(dá)400-500MPa，對(duì)在焊接過程中產(chǎn)生應(yīng)力并超過200MPA時(shí)。進(jìn)入90年代,由于冶金、造船、石化等行業(yè)對(duì)藥芯焊絲需求的增加,國(guó)內(nèi)外藥芯焊絲產(chǎn)業(yè)已開始啟動(dòng)。</p><div
