Abstract
A welding arrangement comprises first and second parts to be welded with an edge portion of the first part and an edge portion of the second part juxtaposed to form a weld zone. An electrically-conductive sheet(s) with a higher melting temperature than a melting temperature of the first and second parts are placed over the weld zone and a force application device is used to apply a lateral compressive force to the weld zone. First and second electrodes are placed in contact with the electrically conductive sheet(s) which are resistively heated and in turn conductively heat the weld zone.
