PROBLEM TO BE SOLVED: To provide a friction welding method and friction welding equipment which enable a plurality of works to be welded with gaps with sufficient strength without using any special tool. SOLUTION: A plurality of works to be welded W1 are pressed by a rotary tool 4 in a non-rotating state to eliminate gaps (402). Thereafter, the tip of the rotary tool 4 in a rotating state is pressed against the works to be welded W1, the works to be welded W1 are softened by the friction heat generated by the rotation of the rotary tool 4, and the work to be welded W1 and the work to be welded W2 subjected to plastic flow and overlapping each other are spot-welded with each other (403 or 405).
