This is a friction welding method for joining a rim and a disc of a disc wheel and apparatus therefore wherein an outside material or a rim and an inside material or a disc, each of which is a component of a disc wheel, are joined together. This friction welding apparatus comprises, typically, a mechanism for fixing firmly the circumference of one materi- al almost entirely circumferentially, a mechanism for rotat- ing another material, a mechanism for generating frictional heat between the two materials, with the inside material fitted into the outside material, by pressurizing the rotat- ed material to the fixed material. This method employs a lap joint process instead of a butt joint process. Either or both of the materials can be provided with a projection on the circumference. A projec- tion absorbs the turning force, inertia force and braking force produced at the time of joining operation to prevent the above forces from being concentrated on a local portion of the materials in process. This prevents the finished products from deformation.
