To provide a means for obtaining a welded product having excellent strength and appearance, which is capable of easily and reliably closing a drawing hole formed at a welding terminal in the friction stir welding.
In the friction stir welding for integrally welding members 1, 1 to be welded with each other by relatively advancing the working head 20 of a friction stir welding tool 2 while the working head is rotated in a buried state, a solder or a brazing filler metal 4a is filled in the drawing hole 3 formed by pulling up the working head 20 at the welding terminal; and the solder or the brazing filler metal 4a is melted by the remaining heat of the friction stir welding remaining in the members 1, 1 and the external heat by a burner or a heating iron, and solidified to integrate the members 1, 1 with each other.
