Abstract: With the development of explosive welding technology, the demands of explosive welding of Zr/Steel plate are increasing. Composite plate of the Zr/Steel, as a specific anti-corrosion composite material, possesses the combined characteristics of the excellent corrosion resistance property of zirconium and the high-strength property of steel. Based on the theory of explosive welding, the dynamic process of the explosive welding was simulated by ANSYS/LS-DYNA software. The influences of gap values on welding joint formations of the R60702/TAI/16MnIII metal sheets were analyzed. The results showed that when the assorted gaps among zirconium and titanium/titanium and steel were 12 mm and 6 mm, the welding quality was favorable. Interfacial bonding of the R60702/TAI/16MnIII composite material obtained by explosive welding experiment was studied by a scanning electron microscope. These experimental data could be used to choose the suitable technical conditions, which was beneficial to guiding production practice.
