Abstract
A friction stir welding apparatus and method maintains a depth of a welded part constant without varying a depth-direction position of a welding tool leading end part relative to welded members. A control device controls an operation of the friction stir welding apparatus, and a holder unit is connected to a swing mechanism unit via a revolving mechanism section, and a welding tool is held to the holder unit. The control device has a first welding mode in which friction stir welding is performed on the basis of a welding condition signal for deciding a welding condition of the welding tool, a swing control signal for controlling the swing mechanism unit, a first hold position decision signal, and a second welding mode in which friction stir welding is performed on the basis of the welding condition signal, the swing control signal, and a second hold position decision signal.
