Abstract
Joint of steels of different hardness through a plastic layer was obtained by explosive welding using an emulsion explosive. In the weld zone, two types of waves were found: large waves and small waves which have not been observed in previous experiments. Empirical relations for calculating the wave dimensions are proposed that take into account the influence of the strength and density of the colliding materials on them. Cracking in the weld zone can be avoided by reducing the wave dimensions.
