As a special processing technology, explosive welding is widely used in fabrication of various metal clad plate. The clad plate not only has high bonding strength, but also can realize large-area composite of different metals. The cost of noble metal can be effectively reduced. In addition to introducing the basic theory, welding window and experimental technology of explosive welding, new technology and new products of explosive welding were discussed in this paper. Furthermore, the application of explosive welding clad plates in different industry fields and their future development prospects are also described.
