Studies allowing the relationship between collision parameters and quality of explosion welded joints were carried out. Formation of the final structure of the contact zone in the joints, determining their strength and ductility, was found to depend mostly upon the mutual effect of two competing mechanisms, i.e. deformation strengthening and relaxation (recovery). Recommendations on selection of welding parameters to ensure the optimal energy balance during the strengthening and structure relaxation processes are given.
