高強鋼用實芯焊絲與藥芯焊絲熔敷金屬工藝性試驗對比研究通過具體的焊接試驗，分析總結出700MPa、900MPa不同級別實芯焊絲與藥芯焊絲各自的焊接工藝特點，為公司焊材的選用提供技術支持。關鍵詞：調質鋼；焊接熱輸入；實芯焊絲；藥芯焊絲一、概述隨著工程機械產(chǎn)品輕量化、大型化的發(fā)展，低合金高強鋼的應用領域越來越多。我公司在履帶式起重機、全地面起重機、礦用挖掘機等工程機械中已大量使用低合金高強鋼，上海優(yōu)瑞卡焊條焊絲廠家。由于低合金高強鋼的焊接工藝在以前沒有相關的資料積累，如何在現(xiàn)有的條件下，解決低合金高強鋼的焊接問題，成為當前**首要的攻關內(nèi)容。因此，本文通過對高強鋼用實芯焊絲與藥芯焊絲進行焊接試驗對比研究，上海優(yōu)瑞卡焊條焊絲廠家，為公司產(chǎn)品制造提供技術支持，同時降低生產(chǎn)成本。二、焊接試驗針對高強鋼母材類型，選擇與之匹配的實芯焊絲和藥芯焊絲進行對比試驗。焊接試板坡口形式如附圖所示。試板坡口形式（1）焊接試板某鋼廠生產(chǎn)的Q690E調質鋼，板厚20mm，上海優(yōu)瑞卡焊條焊絲廠家。其化學成分及力學性能如表1、表2所示。（2）焊接材料的選擇與試驗實芯焊絲：選用奧林康（OERLIKON）公司的Mn3Ni1CrMo，φ（ESAB）公司的okAristRod69，φ；藥芯焊絲：選用斯泰因（STEIN-MEGAFIL）公司的MF742B，φ742M，φ。。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氣體，稱自保護藥芯焊絲。上海優(yōu)瑞卡焊條焊絲廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海優(yōu)瑞卡焊條焊絲廠家,焊條焊絲" src="http://tyunfile.71360.com/UploadFile/shjianmin2/637179275546289062/980359.png"></div><p> 藥芯焊絲焊接時比CO2實芯焊絲的飛濺要小得多，下圖為藥芯焊絲與CO2實芯焊絲飛濺大小的比較。焊接質量好一般CO2實芯焊絲只適合于低碳鋼或強度級別較低的低合金鋼的焊接，而藥芯焊絲則適用于各種材料的焊接，不僅包括各種結構鋼，也包括不銹鋼等特殊材料。藥芯焊絲焊縫的低溫沖擊韌度比實芯焊絲有了很大的提高，可適用于各種重要結構的焊接，而CO2實芯焊絲一般只用于0度以上工作的一般鋼結構。綜合焊接成本：低藥芯焊絲相對價格較高，但其綜合生產(chǎn)成本比焊條電弧焊要低許多，與CO2實芯焊絲大體相當。藥芯焊絲的型號及牌號按GB10045—88規(guī)怎定，藥芯焊絲***部分以英文字母“EF”表示藥芯焊絲代號，代號后面的***位數(shù)字表示主要適用的焊接位置：“0”表示用于平焊和橫焊，“1”表示用于全位置焊。代號后面的第二位數(shù)字或英文字母為分類代號。第二部分在短橫線后用四位數(shù)字表示焊縫金屬的力學性能。如焊絲型號EF03-5042。實際生產(chǎn)中還經(jīng)常用牌號來表示藥芯焊絲的類型。藥芯焊絲生產(chǎn)牌號用如下符號表示：首字母“Y”表示藥芯焊絲；第二位字母表示藥芯焊絲種類，***、第二位數(shù)字表示焊絲特點；第三位數(shù)字表示溶渣類型（或第三位以后之數(shù)字及元素符號表示焊縫金屬化學成分）。上海優(yōu)瑞卡焊條焊絲廠家焊絲主要用于二氧化碳氣體保護焊、埋弧焊和電渣焊。</p><div

具有工藝性能良好、操作方便、焊接質量穩(wěn)定的特點。在不易進行背面充氬保護的管道焊接作業(yè)及高空作業(yè)時其優(yōu)點更為突出，值得在火力發(fā)電廠安裝工程中推廣應用。1、焊接材料與工藝本次試驗中母材采用1Cr18Ni9奧氏體不銹鋼，規(guī)格為Ф42mm×5mm，化學成分及力學性能見表1、表2。焊絲為昆山京群焊材科技有限公司生產(chǎn)的GTS-F308L藥芯焊絲，符合AWS-95R308LT1-5及GB/T17853-99R308LT1-5標準。焊絲規(guī)格為Ф×915mm，藥芯焊絲熔敷金屬的化學成分見表3。坡口尺寸的選擇坡口型式、對口參數(shù)及焊道設計見附圖。由于奧氏體不銹鋼的導熱系數(shù)小而線膨脹系數(shù)大，焊接時變形大。如果在焊接時選用的坡口較大，則將會增多填充金屬，增加焊的擺動距離，降低焊接速度，加大了變形量，增加了焊縫在高溫段的停留時間，增加了產(chǎn)生晶間腐蝕及熱裂紋的可能性，所以在保證焊縫質量及焊工易操作的前提下，應適當減少坡口尺寸。經(jīng)過反復實踐，將坡口尺寸選擇為55°±5°。對口間隙也適當增大，有利于熔渣流到焊縫根部以保護根部焊縫不受氧化。附圖坡口型式與焊道設計焊接位置為45°斜焊（6G）。打底層和該面層全部采用藥芯焊絲進行焊接。層間溫度的控制奧氏體不銹鋼焊接中。</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(chǎn)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(chǎn)效率。例如，采用C808鑄鐵常溫焊接焊絲對內(nèi)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(jīng)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。焊劑為堿性系統(tǒng)的焊材可使熔填金屬獲得非常優(yōu)良的延性與韌性，但作業(yè)性遠較酸性系為差。南京卡斯特林焊條焊絲訂購</p><p
