ABSTRACT:
A method of explosion welding very thin plastic foil to a thicker base material. By fastening a soft material of low acoustic velocity in position on the metal foil prior to carrying out a welding operation, the pressure differences which prevail in the pressure wave incident on the metal foil are equalized in a manner to maintain a uniform pressure wave during the welding sequence. The inventive method enables the explosion welding of thin metal layers having a thickness as low as some few microns.
