②MF742B堿***芯焊絲的特點是：粗熔滴過渡，焊道略凸，煙塵較大，熔渣由氟化物和堿土金屬氧化物組成，焊縫金屬具有較高的沖擊韌性和抗裂紋能力。MF742M金屬粉末型藥芯焊絲的特點是：細熔滴射流過渡，熔渣覆蓋率低，藥芯成分由金屬合金和鐵粉組成，并含有電弧增強劑，熔敷效率高，再引弧性好。③比較實芯焊絲和藥芯焊絲可以看出，藥芯焊絲焊縫金屬Ni的含量比實芯焊絲高，因此焊縫的塑性和韌性更好，-60℃時仍有較高的沖擊韌性。（1）焊接試板：某鋼廠生產的Q960E調質鋼板，板厚20mm。其化學成分及力學性能如表7、表8所示。（2）焊接材料的選擇實芯焊絲：選用奧林康（OERLIKON）公司的Mn4Ni2CrMo，φ（ESAB）公司的okAristRod89，φ；藥芯焊絲：選用斯泰因（STEINMEGAFIL）公司的MF745B，φ1100M，φ。（3）實芯焊絲試驗依據ISO16834標準，并參照焊絲生產廠家提供的相關技術資料，進行了焊絲的試驗研究工作。兩種焊絲的化學成分檢測結果如表9所示。焊接工藝：預熱溫度為150℃，道間溫度為150～170℃；焊接電流為240～280A，電弧電壓為24～30V，保護氣體為80%Ar+20%CO2混合氣體保護；焊接熱輸入～。多道焊時，先焊坡口兩側的焊縫，再焊中間的焊縫。焊后用石棉布覆蓋。安徽優(yōu)瑞卡焊條焊絲藥芯焊絲制造工藝和裝備的發(fā)展歷史藥芯焊絲制造工藝過關并形成商品是50年代和60年代初。</p><div

M）含鉻17%的鐵素體型堆焊藥芯焊絲，用于耐腐蝕的硬面堆焊，具有良好的耐高溫腐蝕性能，以及不銹鋼復合鋼打底焊接，、DY-YD414N（M）含氮馬氏體型堆焊藥芯焊絲，以氮代碳來提高它的硬度及抗裂性，具有良好的耐腐蝕、耐磨損以及耐熱沖擊性能。用于連鑄輥的硬面堆焊焊接，HRC43.焊絲存放編輯1、存放焊絲的倉庫應具備干燥通風環(huán)境，避免潮濕；拒絕水、酸、堿等液體極易揮發(fā)有腐蝕性的物質存在，更不宜與這些物質共存同一倉庫。2、焊絲應放在木托盤上，不能將其直接放在地板或緊貼墻壁。3、存取及搬運焊絲時小心不要弄破包裝，特別是內包裝“熱收縮膜”。4、打開焊絲包裝應盡快將其全部用完（要求在一周以內），一旦焊絲直接暴露在空氣中，其防銹時間將**縮短（特別在潮濕、有腐蝕介質的環(huán)境中）5、按照“先進先出”的原則發(fā)放焊絲，盡量減少產品庫存時間。6、請按焊絲的類別、規(guī)格分類存放、防止錯用。參考資料1.蔣旻,栗卓新,蔣建敏等.高硬度高耐磨自保護金屬芯堆焊焊絲[J].焊接學報,2006,27(1):69-71.．萬方數(shù)據庫[引用日期2017-09-25]詞條標簽：科學百科工程技術分類。</p><p> 并能確保其加工精度，還可使焊區(qū)顏色與母材一致。C808鑄鐵常溫焊接焊絲中含有少量Al，對鑄鐵而言，它是強石墨化元素，有一定的防止在焊接熔合區(qū)產生白口組.織的作用。采用C808鑄鐵常溫焊接焊絲，不必在焊件待焊部位開出的坡口底部加焊藥，并能確保保證優(yōu)良焊接效果。C808鑄鐵常溫焊接比現(xiàn)有的其它各種鑄鐵常溫焊接的熔化焊技術具有更好的抗裂性、可加工性，并可確保其熔合區(qū)Hbmax＜220,且焊區(qū)顏色與母材相比趨于一致。C808鑄鐵常溫焊接焊絲使用工藝過程簡單，焊工易于掌握，在焊前不預熱，焊后不熱處理的前提下，焊后可直接上機械加工線進行切削加工，能節(jié)省材料費用和電能，提高生產效率。例如，采用C808鑄鐵常溫焊接焊絲對內燃機鑄鐵件加工面缺點的修復，可進行小孔的焊接焊補及焊后加工，并能確保保修鑄件的加工精度和質量，從而可使用戶獲得滿意的結果和明顯的經濟效益。實施例：對柴油機機體加工面上的M6螺紋孔處進行焊接焊補修復,其材料為HT250，已完成全部機械加工(見圖1)，要求焊接焊補過程不破壞機體的形狀、位置、精度。采用C808鑄鐵常溫焊接焊絲焊接后，對螺紋孔的重新加工要求達到規(guī)定的技術要求，并要求消除焊接焊補痕跡。主要操作方法：（1）用φ10鉆頭鉆孔。對各種鋼材的焊接，適應性強調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成分。</p><div

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電，電弧容易沿四周的鋼皮旋轉，使得電弧穩(wěn)定性差。因此“0”形只用于制造細徑藥芯焊絲。異形焊絲因鋼皮在整個截面上分布比較均勻，所以電弧燃燒穩(wěn)定，焊絲熔化均勻，冶金反應進行得比較充分，適合于制造直徑。藥芯焊絲的優(yōu)點生產效率高藥芯焊絲可進行連續(xù)的自動化和半自動化生產，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間。同時它的焊接飛濺小，不易堵塞焊嘴，所以比CO2實芯焊絲更適于機器人焊接。熔敷速度快，飛濺小：熔敷速度是指熔焊過程中，單位時間內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，主要是因為它可以使用更大的焊接電流；同時，藥芯焊絲中只含質量分數(shù)為15%~20%左右的藥粉，而焊條的涂料藥皮質量分數(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實芯焊絲相比，由于其電流集中于外表鋼皮，電流密度大，所產生的電阻熱更大；此外，飛濺小，所熔化金屬可以更有效地進入熔池，因而藥芯焊絲甚至比CO2實芯焊絲的熔敷速度還要快。焊絲主要用于二氧化碳氣體保護焊、埋弧焊和電渣焊。安徽優(yōu)瑞卡焊條焊絲</p><p
