Wave formation in explosive welding

Abstract

Abstract The interface between explosively welded metals frequently exhibits a regular wave-like profile. The circumstances under which such a profile develops are not fully understood, and existing theories fail to predict some of its observed characteristics. In the present paper it is suggested that the principal features of wave-like welds are consistent with a mechanism in which the waves arise as a result of hydrodynamic instability between the re-entrant jet and the surface along which it propagates.
