摘要： A temperature sensor is provided inside the protrusion portion of the welding tool, and when welding is performed, the control device controls a rotation speed, a movement speed, or both rotation speed and movement speed of the welding tool, and thus the temperature detected by the temperature sensor is managed so as to fall within the predetermined management temperature range, and welding quality is equalized.

摘要： 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.

摘要： Provided are a friction stir welding apparatus and a friction stir welding method that achieve highly accurate and highly reliable joining while minimizing an effect of bending of a pressing force receiving portion (carrying table) as a result of a press by a joining tool unit. The friction stir welding apparatus joins joining target members by friction stir welding. The friction stir welding apparatus is characterized by including: an apparatus main body; a control device that controls an operation of the friction stir welding apparatus; a C-shaped frame connected to the apparatus main body via a first vertical movement drive mechanism unit; a holder unit connected to one end of the C-shaped frame via a second vertical movement drive mechanism unit; and a joining tool held by the holder unit. The C-shaped frame includes a held portion connected to the apparatus main body via the first vertical movement drive mechanism unit, a holder unit holding portion connected to the holder unit via the second vertical movement drive mechanism unit, and a pressing force receiving portion connected to the other end of the C-shaped frame and receiving a pressing force from the joining tool. The control device includes a first joining mode that performs friction stir welding based on a joining command signal that determines a joining condition of the joining tool, and a first holding position determining signal that determines a first holding position of the first vertical movement drive mechanism unit, and a second joining mode that performs friction stir welding based on the joining command signal and a second holding position determining signal obtained by correcting the first holding position determining signal such that a depth or a range of a joined portion becomes constant in accordance with a state of the pressing force receiving portion. The first joining mode and the second joining mode are included in one joining pass from insertion of the joining tool into the joining target members to extraction of the joining target members.
