ABSTRACT:
An explosion welding method in which plating material is explosion welded to a base material with the aid of a reflected percussion wave generated by a detonating charge. The invention is characterized by placing the explosive charge (1) on that surface of the base material (3) which is remote from the ultimate bonded surface; placing the plating material (2) at a distance from the base material (3) and in contact with a pressure medium (6, 7), said pressure medium functioning to reflect and return a pressure wave introduced in the pressure medium (6, 7); placing along a short length between the base material (3) and the plating material (2) a pressure transmitting element (5) in abutment with both the base material and the plating material, initiation of the explosive charge (1) being effected at said pressure transmitting element (5), such that upon detonation of said charge the percusison wave will be transmitted through the base material (3) and initially through that part of the plating material (2) which lies in contact with the base material through the intermediary of the pressure transmitting element (5), and thereafter through that part of the plating material (2) which lies in contact with the base material (3) through bonding, said percussion wave being further propagated into the pressure medium (6, 7) where said wave is reflected and returned to the plating material which is therewith thrown against the base material.
