**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**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**鋼。由于低合金**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**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**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**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。。</p><p> 3）實芯焊絲試驗ISO16834《**鋼氣體保護電弧焊焊接材料分類》標準對屈服強度≥500MPa（或抗拉強度≥570MPa）的**鋼焊絲的成分、性能及檢測方法做了具體規(guī)定。依據(jù)該標準，進行了焊絲的試驗研究工作。兩種焊絲的化學成分檢測結(jié)果如表3所示。表1Q690E的化學成分（質(zhì)量分數(shù)）（%）成分AlTiCuNbNiVB標準值≤≤≤≤≤≤—表2Q690E的力學性能項目Re/MPaRm/MPaA（%）KV2（-40℃）/J標準值≥690770～940≥14≥34典型值試驗中發(fā)現(xiàn)，焊縫金屬的強度、沖擊韌性值對焊接參數(shù)的變化相當敏感。在焊接電流、電壓一定的情況下，當焊接速度過快，使焊接熱輸入偏低時，焊縫金屬的強度***提高、伸長率變小，低溫沖擊韌性降低；而焊接熱輸入偏大、焊縫冷卻速度慢，或?qū)樱ǖ溃╅g溫度過高時，焊縫金屬的強度、沖擊韌性都有所下降。要獲得理想的焊縫性能，必須嚴格控制預熱溫度、層（道）間溫度，并控制焊接熱輸入在～。焊接工藝：預熱溫度為120℃，道間溫度為120～170℃；焊接電流為240～280A，焊接電壓為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(cè)的焊縫，再焊中間的焊縫。焊后用石棉布覆蓋，保溫緩冷至室溫。力學性能試驗結(jié)果如表4所示。電弧穩(wěn)定劑鈉及鉀可以使電弧保持柔和順暢而且降低飛濺。</p><div

焊接的產(chǎn)品一定要有焊接角度，如果焊接的角度不好，那焊接起來效果就會打折扣，因為此焊絲的原理是完全靠母材的熱傳導熔融焊絲成型的，角度不好用燒到焊絲和焊劑，就會導致焊接失敗。主要運用于不規(guī)則的焊接處比較好是一次需要成型的，還有銅鋁漆包線的焊接，這在電子產(chǎn)品和電機產(chǎn)品上的引線用的特別多。相關的焊接介紹：用電烙鐵或者電爐低溫釬焊銅和鋁的方法銅鋁焊接案例—銅鋁導線的焊接銅鋁焊接視頻–記銅鋁漆包線的焊接銅鋁焊接視頻之M51低溫焊接銅鋁焊接之M51補充說明結(jié)語：靈活運用了以上3種焊接，基本上所有的銅鋁焊接的產(chǎn)品都可以靈活運用了。細節(jié)的產(chǎn)品因為結(jié)構(gòu)和尺寸都不一樣，所以對于這方面有產(chǎn)品改進要求的廠家可以與我們聯(lián)系，拿出你們的想法，我們可以為每一個產(chǎn)品改進尋求一個合理的焊接方案。?焊絲包裝成卷或成桶以避免線材相互糾纏或折損。SKD-11焊條焊絲銷售</p><p
