Discussion on some problems of small face impact bonding effect

Impact bonding has attracted much attention due to its excellent performance. In order to understand impact bonding effect with small face, the interface morphology by impact welding was investigated, the affecting of interface morphology on mechanical properties of welds was discussed, and it is indicated that the wavy interface is important for a reliable weld. In addition, based on bonding process of impact welding workpiece with large face, the formation mechanism of wavy interface was further analyzed. On this basis, the formation mechanism of wavy interface produced for impact welding workpiece with small face was discussed. It is indicated that an artificially set collision angle is necessary to form a wavy interface. Moreover, it is proposed that the effective method to solve the asymmetric problem occurred in impact welding workpiece with small face is to change the bonding surface of flying plate with conical bonding face.
