  1. Explosive welding of multilayer packages: Duration of initial acceleration Professor Sergey Kuzmin, Russia, Volgograd State Technical University

  2. Scheme of Simultaneous Explosion Welding Initial Disposition of Plates in Sheet Pile

  3. Scheme of Simultaneous Explosion Welding Initial Disposition of Plates in Sheet Pile Process of Layer Colliding of Plates

  4. Scheme of Simultaneous Explosion Welding Initial Disposition of Plates in Sheet Pile Process of Layer Colliding of Plates

  5. Models of Process of Colliding Metal Plates in Explosion Welding of Multilayer Sheet Piles Belyaev’s model Model of VSTU • Acceleration Stages: • Starting Stage (Period of Impulse Transfer from Colliding Body to Collided Packet); • Final Stage (Acceleration Provided by Pressure of Detonation Products)

  6. Models of Process of Colliding Metal Plates in Explosion Welding of Multilayer Sheet Piles Mathematical (Computed) Model - Mass of Sheet Pile Model of VSTU - Reduced Time of Acceleration Phase p01 - Maximum Contact Point Pressure - Tuning Indexes
