摘要:

材，在規(guī)劃的路徑上層層堆積成形三維實(shí)體金屬構(gòu)件，具有制造成本低、制造自由度與成形效率高等優(yōu)點(diǎn)，尤其適用于大型尺寸及中低結(jié)構(gòu)復(fù)雜度金屬構(gòu)件的形性一體化成形。近年來，電弧增材制造技術(shù)在國(guó)內(nèi)外得到了廣泛研究與長(zhǎng)足發(fā)展，在電弧增材制造裝備、過程控制、及高性能金屬材料在電弧增材制造過程中的冶金行為等方面均取得了有價(jià)值的研究成果，且電弧增材制造關(guān)鍵金屬構(gòu)件在航空、航天、船舶等高端制造領(lǐng)域均具有成熟的應(yīng)用案例。分別從電弧增材制造裝備系統(tǒng)、過程控制策略、及電弧增材制造過程中高性能金屬材料的冶金行為3個(gè)方面綜述了國(guó)內(nèi)外的重要研究成果，指出了目前研究中存在的不足，并列舉了電弧增材制造的典型應(yīng)用案例，最后對(duì)電弧增材制造技術(shù)未來的發(fā)展方向進(jìn)行了展望。

Abstract:

Wire arc additive manufacturing (WAAM) is one of the most rapidly developed additive-manufacturing technologies in recent years, which utilizes the arc as heat source to melt the metal wire, and realizes the forming of 3D solid metal components by depositing on the planned path. WAAM possesses the advantages of low manufacturing cost, high manufacturing freedom and high forming efficiency, especially suitable for the shape and properties integration forming of large size and low complexity components. In recent years, WAAM technology has received extensive research and development, and valuable researches have been achieved in the aspects of WAAM equipment, process control, metallurgical behavior of high-performance metal during WAAM process, etc. And there are mature application cases of WAAM for key metal components in aviation, aerospace, ship and other high-end manufacturing fields. This article presents a comprehensive overview of development of WAAM, including: WAAM equipment system, process control strategy, and metallurgical behavior of high-performance metal materials during WAAM process. The shortcomings of current researches are pointed out, and typical application cases of WAAM are listed. Finally, the future development direction of WAAM technology is prospected.
