In a friction stir welding method, a tool is inserted into a joint to be made between a first member and a second member while the tool is rotated, and the first member and the second member, and the tool are relatively moved along the joint such that the first member and the second member are softened, to perform friction stir welding of the first member and the second member. The method includes acquiring a proper rotation speed of the tool for at least two relative movement speeds, acquiring a proper condition of the proper rotation speed for the at least two relative movement speeds, based on the proper rotation speed for the at least two relative movement speeds, and performing the friction stir welding in a condition that satisfies the proper condition in a speed range in which the at least two relative movement speeds exceed 3 m/min.
A friction stir welding method in which a tool is inserted into a joint to be made between a first member and a second member while the tool is rotated, and the first member and the second member, and the tool are relatively moved along the joint to be made such that the first member and the second member are softened, to perform friction stir welding of the first member and the second member, the friction stir welding method comprising:
