Abstract
A friction stir welding apparatus is used at a butted portion where a second workpiece is butted against a first workpiece such that the second workpiece is upright on the first workpiece. The friction stir welding apparatus includes: a rotary tool that is plunged into one inner corner of a pair of inner corners that are positioned, at the butted portion, on both sides of the second workpiece, respectively; an inner corner presser that presses the other inner corner of the pair of inner corners; and a mover that moves the rotary tool and the inner corner presser along a direction in which the butted portion extends. The inner corner presser includes a pressing roller that presses the other inner corner while rolling in a state where the inner corner presser is being moved by the mover.
