Abstract
A charging system for seam welding two or more workpieces by means of explosion welding, comprising an explosive charge and an inert impulse-transmitting body located between the explosive charge and the workpiece nearest the charge. The invention is characterized in that the surface (11) of the inert body (2) facing the workpiece is so configured in a plane extending at right angles to the longitudinal extension of the ultimate weld seam that the angle .alpha. between the surface (11) and the workpiece (3) varies from the center line (C--C) of the inert body (2) perpendicularly to the surface of the workpiece and outwardly from the center line.
