(Means for solving the problem) A means for solving the above technical problem is to provide a plurality of clutch covers on the inner circumference of an automobile clutch cover consisting of a cover core, a pressure plate, and a diaphragm spring. In a pivot ring made of a hard steel wire that is positioned and held by a tongue, the hard steel wire is cut into a ring shape, and when the opening of the pivot ring is welded, the welded part of the pivot ring is shaped like the pivot ring. This is a pivot ring welding method in which the pivot ring is held with a matching copper backing metal and joined by TIG welding.

の必要がなく接合できるものである。(Operation) The technical means operates as follows. That is, by holding the opening of the pivot ring in the groove on the backing metal and performing TIG welding, an arc discharge is generated using a tungsten electrode, and inert gas (Ar) is
Since welding is performed while blocking air and preventing oxidation of the welded part, there is no need for upsetting.As a result, no burrs are generated on the surface of the hard steel wire, so welding can be performed without the need for removal.

By performing welding, there is no burr generation in the welded part, and as a result, there is no need for deburring man-hours, making it possible to significantly reduce costs. As mentioned above, during butt welding, the rings are welded while moving to butt together, resulting in a misalignment of the welded parts 11, which is disadvantageous in terms of strength and function as a pivot ring.However, in this case, the alignment centers of the welded parts are shifted. It is possible to manufacture a high-quality pivot ring without causing any deviation in the roundness of the pivot ring.
