摘　　要：使用爆炸焊接对高纯铝与铜坯料进行连接,将超声C-scan应用于爆炸焊接复合板坯的无损探伤,并从坯料微观组织和力学性能等方面分析了焊接性能。结果表明,C-scan能够在不破坏板坯的情况下,全面快速检测爆炸焊合率;焊接完成后,铝板坯晶粒间有条状应力带,热处理后应力带消失且晶粒未异常长大。爆炸焊接能实现高纯铝与铜的高强度焊接,焊接强度约43MPa。High purity aluminum and copper were bonded by explosive welding. The bonding plate was nondestructive tested by C-scan. The welding properties of Al/Cu composite plate were analyzed in terms of microstructure and mechanical properties. The results show that C-scan, as a nondestructive testing method, can detect bonding quality rapidly. Existing in combined interface after welding, strip stress zones disappear with no grain growth after heat treatment. Explosive welding can realize the strength weld between high purity aluminum and copper with tensile strength of combined interface of about 43 MPa.
