PROBLEM TO BE SOLVED: To provide an aluminum or aluminum alloy material for friction stir spot welding, a material that can reduce a pressing load at the time of welding and that can bring a joint with a high joining strength, and also to provide a friction stir spot welding method.;SOLUTION: The average roughness on the front and the back surface of aluminum alloy materials 1, 2 as the materials to be joined in friction stir spot welding is made ≥0.05% of the plate thickness. Also, where the average roughness in one direction is Ra1, and the average roughness in the direction orthogonal to that one direction is Ra2, and if Ra1≥Ra2 is satisfied, the difference (Ra1-Ra2) between the average roughness Ra1 in the one direction and the average roughness Ra2 in the direction orthogonal thereto is made ≤10% of the average roughness Ra1 in the one direction.;COPYRIGHT: (C)2006,JPO&NCIPI
