摘要

为实现铜与钛异种金属的可靠连接，探索了一种热辅助超声波焊接的工艺方法。以MCGS触摸屏作为上位机，陶瓷加热片作为辅助加热热源，搭建了热辅助超声波焊接成套装置。通过MCGS软件开发的人机界面及控制程序，实现了热辅助超声波焊接工艺过程的实时控制。通过对不同加热温度下Cu/Ti超声波焊接接头力学性能和微观组织的分析，建立了热辅助超声焊接过程界面反应模型，以此阐释了Cu/Ti热辅助超声波焊接接头的形成机理。试验结果表明，辅助加热不仅提高了焊接区峰值温度，还促进了界面元素的相互扩散，使反应区的宽度和有效连接面积显著增加，机械嵌合作用明显增强，是Cu/Ti接头抗剪切强度显著提高的主要原因。

Abstract

In order to achieve a reliable connection between copper and titanium dissimilar metals, a heat-assisted ultrasonic welding process method was explored. Firstly, a heat-assisted ultrasonic welding package was built using an MCGS touch screen as the host computer and a ceramic heating pad as the auxiliary heating heat source. Secondly, the human-machine interface and control program developed by MCGS software achieves real-time control of the heat-assisted ultrasonic welding process. Finally, through the analysis of the mechanical properties and microstructure of Cu/Ti ultrasonic welded joints under different heating temperatures, an interface response model of the thermal-assisted ultrasonic welding process was established to explain the formation mechanism of Cu/Ti thermal-assisted ultrasonic welded joints. The analysis of the experimental results shows that the auxiliary heating increases the peak temperature of the weld zone and promotes the mutual diffusion of the interfacial elements, resulting in a significant increase in the width of the reaction zone and the effective joint area, and a significant increase in the mechanical embedding effect, which is the main reason for the significant increase in the shear strength of the Cu/Ti joint.
