ABSTRACT:
A method is provided for welding an edge surface of a curved metal brake shoe web to a metal brake shoe table. The brake shoe table surface has a greater radius of curvature than the brake shoe web prior to welding. The method consists of the steps of positioning the brake shoe table in longitudinal alignment with the brake shoe web with one end portion of the table surface abutting the brake shoe web surface over a predetermined distance and with the table surface diverging away from the brake shoe web edge to form a vertex where the surfaces abut. The abutting surfaces of the brake shoe web and the brake table are then pressed together at the vertex. The diverging surfaces of the brake shoe web and the brake table are contacted by separate electrodes. The high frequency alternating potential is then provided to each of the electrodes contacting the table and the web to induce a current to flow therebetween and thereby heat the interfacing surfaces in the area of the vertex. The brake shoe table and the brake shoe web are then rotated together along a curvelinear path while the pressure therebetween and the high frequency heating current applied thereto is maintained thereby welding the interfacing surfaces together. The rotation is stopped before the electrodes contacting the table traverse the other side of the diverging table surface and the alternating potential is allowed to reduce thereby allowing the high frequency heating current to dissipate.
