  • Patent number: 11794273
    Abstract: 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.

  • Patent number: 11285562
    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.
