| description | Different from the traditional parallel method, double vertical explosive welding adopts a closed charge structure, and two composite plates are formed by one explosion. The energy distribution and interface morphology in the parallel methods and double methods were studied by numerical simulation and experiments. The theory of “energy flow in stages during explosive welding” was first proposed and energy balances at the start and end welding were obtained in this paper. The temporal and spatial distribution of the relevant parameters was analyzed. The value and proportion of each energy were calculated in sections by numerical simulation. The results showed that the detonation products in double method had higher internal energy and lower kinetic energy. The collision velocity obtained by the two methods was close. The kinetic energy of the flyer plate, plastic deformation energy and jet energy in the double method were about twice those in the parallel method. The experimental results showed that the dimension of the interface waves in two methods was close, but more melted microstructures were observed in the double method, whose compositions were mainly TiFe2 and TiFe3. Double vertical explosive welding improved energy efficiency and saved at least half of the explosives. |
