Abstract : The patent describes explosive spot welding of relatively-thin metal alloy plates or sheets accomplished by using a very-narrow angle between the plates or sheets to be welded and with a short overlap in which one edge of one sheet intersects the contiguous face of the other sheet, before welding, and forming a line contact. The welding force is applied by an explosive charge which is provided by a relatively small-size pellet placed over the center of the overlap above the upper-most panel or sheet to be joined. Only slight holding force is applied to the parts to be joined and this is only sufficient to hold such parts in position one with respect to the other before the weld takes place.
