PARAMETERS CALCULATION SOFTWARE OF EXPLOSIVE WELDING CONDITIONS
(pp. 21-27)

Abstract. Application of new CLMs (Composite Layer Materials) currently involves synthesis of the internal structure, selection of the optimal technology flow diagram and parameters for its explosion welding. Process of explosive welding is characterized by a large numbers of dynamic, energy and physical parameters, describing initial welding conditions and external processes ensuring acceleration and collision of bodies being joined. The article considers calculation principles of collision explosive welding parameters to ensure sound joint with minimal structure and chemical composition heterogenity. The specific energy spent for plastic deformation was used as criterion parameter to determinate lower boundary of explosive welding (criterion used by E. I. Astrov). Therefore, the position of the lower boundary is affected primarily by mechanical properties of the metals and the ratio of their collision parameters. The one-dimensional and two-dimensional flying methods were used to model the interface geometry (cladding plate) and to determine energy and kinematic parameters (explosive welding conditions) such as the impact velocity, the collision point velocity, the dynamic angle, the plastic strain energy for various stand-off distance. Thanks to a large number parameters under consideration, the calculation of explosive welding condi-tion is very complicated and multi-alternative. The specialized applied software was developed to determine explosive welding conditions for this purpose. The results obtained from calculations were validated by means of pin-measurements and the variable-resistance transducer methods. The misalignment between theory and experiment was less than 10…15 %. The software allows design and optimization of the technology conditions of explosive welding two layer composite materials without the labor-extensive and prolonged experiments.

Keywords: Explosive welding; Composite materials; Plastic deformation; Welding conditions.
