A study on explosion welding defects of large-sized plates

In engineering application of explosion welding of large-sized Ti/steel plates,welding defects are always found in the particular area of plate's boundary.In order to solve this problem,the dynamic process of explosion welding is investigated by the numerical simulation.Folding deformation can be discovered during the explosion welding based on the research on the morphological changes of the flyer plate at different times.The calculation results are in good agreement with the experiments.The studies show that folding deformation is a crucial problem which should be noticed in the process of explosive welding.The reasons for the folding deformation are discussed in the paper.The conclusion can provide a reference for the development of explosion welding technology.
