Study on Defects of Large-sized Ti/Steel Composite Materials in Explosive Welding

In this paper, the dynamic process of explosive welding for large-sized plates is studied by numerical simulation. Folding deformation could be found during the process of explosive welding based on the studies on the morphological changes of the flyer plate at different time. The calculation results are in good agreement with the practical projects. The study shows that folding deformation is a crucial problem which should be noticed in the process of explosive welding, and the reasons for folding deformation are discussed in the paper. The conclusion can give reference for the development of explosive welding technology.
