    • Abstract
  • The different explosive welding process of composite tube welding induces a different progress in welding process compared to the composite plate welding. The relatively confined space of the composite tube lead to difficulties in the observation of the welding process. This paper simulate the explosive welding process of composite tube through software AUTODYN. On the basis of the verification of the model, the formation of the jet and the unique structure of waveform interface were analyzed. The jet induced wavy bonding satisfies the penetrating mechanism hypothesis. The simulation results are in good agreement with the experimental results, which provide important information for the further study on the wave structure and jet formation mechanism of explosive welding.
