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.
Claims20
A method for dielectric welding of a product comprising first and second layers and an electrically-conductive member attached to at least the first layer, the method comprising:
- providing a first electrode;
- placing the first layer adjacent to the first electrode with the electrically-conductive member projecting into a recess in a buffer material adjacent to the first electrode and the second layer adjacent to the first layer on its side away from the first electrode;
- compressing the first and second layers between the first electrode and a second electrode complementary to the first electrode;
- applying a high frequency welding potential between the first and second electrodes for a time sufficient to cause the first and second layers to fuse in their portions between the first and second electrodes.
A method for dielectric welding of a product comprising a plurality of layers of a dielectric material and an electrically-conductive member passing through at least one layer of the plurality of layers, the method comprising:
- placing the plurality of layers between first and second electrodes with the electrically-conductive member projecting into a recess in an electrically non-conducting buffer material adjacent to one of the first and second electrodes;
- compressing the plurality of layers between the first and second electrodes;
- and,
- applying a high frequency welding potential between the first and second electrodes for a time sufficient to cause the plurality of layers to fuse in their portions between the first and second electrodes.
