Abstract
Dielectric welding apparatus has opposed electrodes that can be engaged on either side of a product to be welded and a dielectric welding power supply that supplies welding potentials to the electrodes. The apparatus includes electrically insulating buffer material adjacent to at least one of the electrodes. A recess formed in a surface of the buffer material receives an end of an electrically-conductive member in the product. The buffer material prevents arcing between the electrodes and the electrically-conductive member.
