摘要
Explosive welding quality is deeply related to the interface morphology, and the interface morphology is mainly dependent on some process parameters such as collision velocity, welding angle, and material strength (Zeng et al. Weld World 63:967-974. 1; Zeng et al. Met Mater Eng 49(6):1977-1983. 2; Zeng et al. Baozha Yu Chongji/Explosion Shock Waves 39(5): 7. 3). In this paper, the quantitative prediction method of explosive welding interface morphology was investigated based on the fluid elastoplastic theory and experimental results. In addition, a model of shock wave propagation was proposed to study the gas movement in the gap between the plates during the welding process. The results showed that good agreement of interface morphology can be observed between the quantitative calculation results and the experiment results. The "channel effect" of gas shock wave between the base and cladding plates was proposed, which can cause the tail of the cladding plate to be lifted and change the welding parameters before the collision.
