  A sequence of the interface transition states was investigated. A transition
state has been found, during which cusps look like splashes. Images of the
splashes for different joints have been obtained. The processes of
self-organization of the splashes into a quasi-wave surface and a perfect wavy
surface have been revealed. Simulations experiments have been conducted.
Heterogeneity and the interface bending of one of the contacting materials have
been detected. They imitate the heterogeneity on the interface arising upon
explosive welding.
