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(jié)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(shù)支持。關(guān)鍵詞：調(diào)質(zhì)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(yīng)用領(lǐng)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。由于低合金高強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，解決低合金高強鋼的焊接問題，成為當前**首要的攻關(guān)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，為公司產(chǎn)品制造提供技術(shù)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(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實芯焊絲：選用奧林康（OERLIKON）公司的Mn3Ni1CrMo，蘇州模具焊條焊絲批發(fā)，蘇州模具焊條焊絲批發(fā)，φ（ESAB）公司的okAristRod69，φ；藥芯焊絲：選用斯泰因（STEIN-MEGAFIL）公司的MF742B，蘇州模具焊條焊絲批發(fā)，φ742M，φ。。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。蘇州模具焊條焊絲批發(fā)</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(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(yīng)進行得比較充分，適合于制造直徑。藥芯焊絲的優(yōu)點生產(chǎn)效率高藥芯焊絲可進行連續(xù)的自動化和半自動化生產(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?。喝鄯笏俣仁侵溉酆高^程中，單位時間內(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，主要是因為它可以使用更大的焊接電流；同時，藥芯焊絲中只含質(zhì)量分數(shù)為15%~20%左右的藥粉，而焊條的涂料藥皮質(zhì)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(chǎn)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。</p><p>
