Abstract：Abstract: The reason for the explosion welding defects of large-sized plates is not explicitly found because of the particularity in the process of explosion welding. In this paper, the cause of the defects during the explosive welding for plates sized from 3.5m to 7.0m is investigated by the Dynamic nonlinear numerical simulation. Folding deformation can be found during the explosion welding based on the study on the changes of the flyer plate at different time. The study shows that the occurrence of the plates’ folding deformation is closely related to the size of the used plates. There are some regular relations between the duration, the position, the maximum spatial depth of folding deformation and the size of the metal plates.
