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. 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 c…
