摘要
冷金属过渡连接技术可数字化协调送丝运动和熔滴过渡,通过焊丝回抽帮助熔滴脱离焊丝,在异种金属焊接领域中具有独特的优势。阐述了铝-钢、镁-钢、铝-钛、镁-钛、铜-钛、镁-铜、铝-铜、铝-镁等异种金属冷金属过渡技术的发展及研究进展,指出界面反应机制、金属间化合物层、接头质量的控制方法、焊接新材料等是需要研究的重点和方向。
The cold metal transfer welding technology can digitally coordinate wire feeding movement and droplet transfer, and the droplet is removed from the wire by wire discharge. It has unique advantage in the field of dissimilar materials welding. The development and research progress of dissimilar metals cold metal transfer welding technology were introduced, which included Al-steel, Mg-steel, Al-Ti, Mg-Ti, Cu-Ti, Mg-Cu, AI-Cu and Al-Mg. It was pointed out that the interfacial reaction mechanism, intermetallic compounds layer, the control methods of joint quality and the new welding materials were the focus and direction of research.
