PROBLEM TO BE SOLVED: To provide a friction pressure welding method where, even if three or more components are welded by friction pressure welding, the core dislocation of a welded body as a finished product can be suppressed. SOLUTION: The friction pressure welding method where three or more components 7a to 7e are successively subjected to friction pressure welding by a friction pressure welding device 1, so as to be integrally formed comprises: a stage where the component 7a set in a stationary part 2 and the component 7b set in a rotary part 3 are subjected to friction pressure welding; a stage where the maximum swinging directionαof a welded body 8 by the friction pressure welding is measured; a stage where the welded body 8a is set in the stationary part 2 in such a manner that the maximum swinging directionαbecomes a direction rotated by about 180°(¾α-θ¾≈180°) or within the range of 180°±30°(150°≤¾α-θ¾≤210°) to the directionθin which the swinging of the friction pressure welding device 1 is easy to occur; and a stage where the welded body 8a set in the stationary part 2 and the following component 7c set in the rotary part 3 are subjected to friction pressure welding, and these stages are continuously repeated.
