Abstract
A method and apparatus for wheel nut cap welding in which two capped wheel nuts are axially aligned with their capped ends facing one another and spaced apart from one another by a cylindrical electrically conductive ring the opposite ends of which contact the sheath of the capped nut adjacent the area at which the weld has to be formed. The capped nuts and ring are telescopically assembled within a cylindrical guide sleeve of insulating material so that the conical, threaded opening end of each of the nuts extends beyond the ends of the guide sleeve where they are each contacted by cylindrical electrodes having conical indentations to fit the nut conical ends. The cylindrical ring positioned between the nuts constitutes a connecting electrode within the guide sleeve of insulating material so that the electrical current may pass from one of the electrodes in contact with the conical end of a nut through the nut and connecting electrode and to the other electrode contacting the conical end of the other nut to form a welding circuit. The welding method and apparatus provides the advantages of producing two welded capped nuts per welding cycle while developing a more consistent welding current pattern and greater efficiency in use of welding current while utilizing an easily maintained electrode in contact with the sensitive welding surfaces of the caps.
