PROBLEM TO BE SOLVED: To provide a frictional agitation joining method capable of restraining damage of a metallic member in joining, and capable of preventing joining failure by a metal shortage.SOLUTION: The frictional agitation joining method is provided for joining the metallic members 1 and 2 by using this joining rotary tool F having an agitation pin F2, and includes a butting process of forming a butting part J1 by butting the mutual metallic members 1 and 2 at an angle, a padding welding process of covering the inner corner with welding metal M by applying padding welding to the inner corner of the mutual metallic members 1 and 2 formed in the butting process, and an inner corner joining process of executing frictional agitation joining of the butting part J1 by plastically fluidizing the welding metal M and the mutual metallic members 1 and 2 by inserting only the rotated agitation pin F2 into the inner corner. |
