Abstract: A method of manufacturing an outer joint member of a constant velocity universal joint includes forming cup and shaft members of medium carbon steel, forging the cup member to have integrally formed cylindrical and bottom portions, and machining a joining end surface on an outer surface of the bottom portion after the forging. The method also includes preparing the shaft member to have a joining end surface to be joined to the bottom portion of the cup member, which is formed by machining, bringing the joining end surfaces of the cup and shaft members into abutment against each other and welding the cup and shaft members by radiating a beam from an outer side of the cup member to an abutment portion between the cup and shaft members in a radial direction of the cup member.
