Abstract: Different from the traditional welding processes, HVIW might effectively reduce the formation of heat-affected zones and continuous intermetallic compounds, thus the mechanics properties of the bonding zones were ensured. HVIW might almost achieve the connection between arbitrary metal materials, which had a wide range of possibilities for further developments and applications. HVIW might be divided into two processes: driving flyer plate moving at high speed and impact welding. HVIW included explosive welding, magnetic pulse welding, laser impact welding and vaporizing foil actuator welding. The basic principles, characteristics and application fields of four kinds of impact welding processes were briefly introduced. The metallurgical studies, interface phenomena, mechanics properties, welding window and numerical simulation in impact welding processes were summarized. Some problems in current researches were analyzed, which provide a basis for further researches.

Key words: high velocity impact welding（HVIW）, welding technology, microstructure characteristic, mechanics property, numerical simulation

摘要： 与传统的熔焊工艺不同，高速冲击连接可以有效地减小热影响区和连续金属间化合物的形成，从而保证结合区域的机械性能，并且几乎能够实现任意金属材料间的连接，具有广阔的发展和应用前景。高速冲击连接可以分为驱动飞板高速移动和冲击连接两个过程，主要包括爆炸连接、电磁脉冲连接、激光冲击连接和汽爆连接四种工艺。简要介绍了四种冲击连接过程的基本原理、特点及应用范围，综述了冲击连接过程中的冶金行为、界面现象、力学性能、焊接工艺窗口和数值模拟等方面的最新进展，分析了目前研究中存在的一些问题，为进一步的研究提供了依据和参考。
