Abstract
A friction stir welding device includes a table that has a placement surface on which a workpiece is to be placed and is rotatable about a table rotation axis intersecting the placement surface, a tool holder movable relative to the table in a direction along the placement surface and rotatable about a holder rotation axis parallel to the table rotation axis, and a welding tool supported by the tool holder and rotating about a tool rotation axis intersecting the holder rotation axis. A control device has a biaxial operation mode in which the welding tool in a rotating state is pressed against a welding portion of a side surface of the workpiece, the welding tool is relatively moved along the welding portion by rotating the table, and the tool holder is rotated so that the welding tool is directed in a normal direction of the welding portion.
