高強(qiáng)鋼用實(shí)芯焊絲與藥芯焊絲熔敷金屬工藝性試驗(yàn)對(duì)比研究通過具體的焊接試驗(yàn)，分析總結(jié)出700MPa、900MPa不同級(jí)別實(shí)芯焊絲與藥芯焊絲各自的焊接工藝特點(diǎn)，為公司焊材的選用提供技術(shù)支持。關(guān)鍵詞：調(diào)質(zhì)鋼；焊接熱輸入；實(shí)芯焊絲；藥芯焊絲一、概述隨著工程機(jī)械產(chǎn)品輕量化、大型化的發(fā)展，低合金高強(qiáng)鋼的應(yīng)用領(lǐng)域越來越多。我公司在履帶式起重機(jī)、全地面起重機(jī)、礦用挖掘機(jī)等工程機(jī)械中已大量使用低合金高強(qiáng)鋼。由于低合金高強(qiáng)鋼的焊接工藝在以前沒有相關(guān)的資料積累，如何在現(xiàn)有的條件下，解決低合金高強(qiáng)鋼的焊接問題，成為當(dāng)前**首要的攻關(guān)內(nèi)容。因此，本文通過對(duì)高強(qiáng)鋼用實(shí)芯焊絲與藥芯焊絲進(jìn)行焊接試驗(yàn)對(duì)比研究，為公司產(chǎn)品制造提供技術(shù)支持，同時(shí)降低生產(chǎn)成本。二、焊接試驗(yàn)針對(duì)高強(qiáng)鋼母材類型，選擇與之匹配的實(shí)芯焊絲和藥芯焊絲進(jìn)行對(duì)比試驗(yàn)。焊接試板坡口形式如附圖所示，山東焊條焊絲工廠。試板坡口形式（1）焊接試板某鋼廠生產(chǎn)的Q690E調(diào)質(zhì)鋼，板厚20mm。其化學(xué)成分及力學(xué)性能如表1、表2所示。（2）焊接材料的選擇與試驗(yàn)實(shí)芯焊絲：選用奧林康（OERLIKON）公司的Mn3Ni1CrMo，φ（ESAB）公司的okAristRod69，山東焊條焊絲工廠，φ；藥芯焊絲：選用斯泰因（STEIN-MEGAFIL）公司的MF742B，φ742M，φ，山東焊條焊絲工廠。。?焊絲焊補(bǔ)時(shí)熱影響區(qū)非常小，不會(huì)產(chǎn)生內(nèi)應(yīng)力。山東焊條焊絲工廠</p><div

src="http://tyunfile.71360.com/UploadFile/shjianmin2/637179265669208984/676197.png"></div><p> 控制層間溫度對(duì)避免產(chǎn)生晶問腐蝕及熱裂紋尤為重要，并可控制焊縫根部的氧化，因此焊接時(shí)應(yīng)盡量選用小線能量快速焊。層間溫度應(yīng)控制在50~60℃。焊接工藝參數(shù)焊接前將坡口內(nèi)外邊緣10~20mm處焊件表面的油污、水、銹等清理干凈，露出金屬光澤。焊接工藝參數(shù)的選擇，見表4所示。2、焊縫外觀檢驗(yàn)及性能試驗(yàn)焊縫外觀成形良好，尤其是焊縫背面成形美觀，無焊瘤、未熔合、未焊透等缺點(diǎn)。射線檢測按照J(rèn)B/T4730《承壓設(shè)備無損檢測》標(biāo)準(zhǔn)進(jìn)行，II級(jí)及以上為合格，經(jīng)評(píng)定為合格。力學(xué)性能試驗(yàn)按GB/T228和GB/T2653規(guī)定的試驗(yàn)方法，對(duì)焊接接頭試樣進(jìn)行了拉伸試驗(yàn)和彎曲試驗(yàn)，拉伸實(shí)驗(yàn)結(jié)果如表5所示，彎曲試驗(yàn)結(jié)果如表6所示。實(shí)驗(yàn)結(jié)果為合格。3、焊接操作要領(lǐng)不銹鋼藥芯焊絲是利用焊絲中間的藥粉熔化后，在熔敷金屬背面和正面形成熔渣進(jìn)行保護(hù)，所以根部焊接時(shí)與實(shí)芯焊絲焊接的操作方法、電弧擺動(dòng)頻率、填絲量有較大區(qū)別。（1）在焊接過程中，焊要做圓弧形擺動(dòng),其目的是使鐵水和熔渣加速分離，便于觀察熔池，同時(shí)也可增加母材坡口兩側(cè)的熱輸入量，防止出現(xiàn)單邊未熔合。在填充焊絲時(shí)，應(yīng)將焊絲送到熔池根部并向下輕壓一下，以保證根部熔透及根部內(nèi)成形。。上海日亞焊條焊絲生產(chǎn)廠美國專利公布了一種帶芯絲的藥芯焊絲制造方法,芯絲上壓涂一層膏狀藥皮,就成了焊絲中的藥芯。</p><div

焊接生產(chǎn)中大量采用焊條電弧焊。在工業(yè)發(fā)達(dá)國家，焊條的產(chǎn)量仍占焊材總產(chǎn)量的30%左右。在我國，這一比例為80%~90%左右。但從世界焊材發(fā)展的總趨勢看，隨著氣體保護(hù)焊工藝的***應(yīng)用和藥芯焊絲不斷崛起，手工焊條總的需求量會(huì)逐年下滑，今后的主要應(yīng)用對(duì)象是修配及某些特殊場合。在焊絲的生產(chǎn)上，埋弧焊焊絲在我國已經(jīng)應(yīng)用得非常***，埋弧焊用薄鋼帶也有應(yīng)用。近年來氣體保護(hù)焊和藥芯焊絲的應(yīng)用得到很大發(fā)展，使焊絲在消耗焊材中所占的比例日益增加，成為一種重要的焊接材料。焊絲的分類焊絲按其結(jié)構(gòu)可分為實(shí)芯焊絲和藥芯焊絲。實(shí)芯焊絲多為冷拔鋼絲；而藥芯焊絲則是由薄鋼帶縱向折迭并加入藥粉后，再行拉拔而成。實(shí)芯焊絲使用的歷史比較長，為目前主要使用的焊絲；藥絲焊絲的使用比起實(shí)芯焊絲來晚了許多，但由于其具有一系列優(yōu)點(diǎn)，在生產(chǎn)中應(yīng)用得越來越多。焊接用的焊絲按其保護(hù)方式又可分為兩大類：一類是焊接時(shí)焊絲只起填充金屬和導(dǎo)電的作用，施焊過程中要依靠焊劑保護(hù)或氣體保護(hù)，如埋弧焊、CO2氣體保護(hù)焊中使用的實(shí)芯焊絲和CO2氣體保護(hù)焊中使用的部分藥芯焊絲；另一類焊絲在焊接過程中不需要外加氣體或焊劑的保護(hù)。</p><p> 藥芯焊絲焊接時(shí)比CO2實(shí)芯焊絲的飛濺要小得多，下圖為藥芯焊絲與CO2實(shí)芯焊絲飛濺大小的比較。焊接質(zhì)量好一般CO2實(shí)芯焊絲只適合于低碳鋼或強(qiáng)度級(jí)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*包括各種結(jié)構(gòu)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(shí)芯焊絲有了很大的提高，可適用于各種重要結(jié)構(gòu)的焊接，而CO2實(shí)芯焊絲一般只用于0度以上工作的一般鋼結(jié)構(gòu)。綜合焊接成本：低藥芯焊絲相對(duì)價(jià)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(shí)芯焊絲大體相當(dāng)。藥芯焊絲的型號(hào)及牌號(hào)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(hào)，代號(hào)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(hào)后面的第二位數(shù)字或英文字母為分類代號(hào)。第二部分在短橫線后用四位數(shù)字表示焊縫金屬的力學(xué)性能。如焊絲型號(hào)EF03-5042。實(shí)際生產(chǎn)中還經(jīng)常用牌號(hào)來表示藥芯焊絲的類型。藥芯焊絲生產(chǎn)牌號(hào)用如下符號(hào)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(diǎn)；第三位數(shù)字表示溶渣類型（或第三位以后之?dāng)?shù)字及元素符號(hào)表示焊縫金屬化學(xué)成分）。在埋弧焊、電渣焊和其他熔化極氣體保護(hù)電弧焊時(shí)，焊絲既是填充金屬，同時(shí)焊絲也是導(dǎo)電電極。</p><div
