Use of Emulsion Explosives in Experimental Studies of Flows in the Bonding Zone in Explosive Welding

摘要

Bonding of steels of different hardness through a ductile layer was obtained by explosive welding using an emulsion explosive. In the bonding 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 size are proposed that take into account the influence of the strength and density of the colliding materials on them. Cracking in the bonding zone can be avoided by reducing the wave size.
