ABSTRACT:
The invention is an apparatus and a process for the explosive joining of a flyer plate and a base plate. The apparatus consists of a flyer plate positioned over a base plate. The flyer plate has a notch containing a filler material in intimate contact with the flyer plate. An adhesive means holds a ribbon explosive partially overlapping the notch in the flyer plate. A detonating means initiates the ribbon explosive that drives the flyer plate to accomplish a high velocity, angular collision between the mating surfaces. This collision creates surface melts and effacing bonding, resulting in electron-sharing linkups between the plates. An unbonded tab of the flyer plate is lifted and levered to apply a peeling stress to the limit of the bond. The unbonded tab fractures at a base of the notch leaving a bond to an edge of the attached flyer plate.
