ABSTRACT:
A method for making an electrical bushing having an enlarged intermediate portion and reduced portions at opposite ends. The method is characterized by the steps of mounting an annular flange around one of the reduced portions to form a peripheral gutter adjacent to the one portion, mounting a cap on the other of the reduced portions to form a peripheral gutter adjacent to the other portion, placing a solid solder ring in each gutter, and with the open sides of the gutters upright, heating the solder rings to a molten temperature and cooling the molten solder to below its melting temperature in order to provide a joint between the flange and the one portion and the cap and the other portion.
