Document Type and Number:
WIPO Patent Application WO/2019/189509
Kind Code:
A1
Abstract:
A friction stir welding device comprising a device main body (2), a control device (12), a C-frame (4), a holder part (6), and a welding tool (7), wherein: the C-frame (4) comprises a held part (4a) that is connected to the device main body (2) by a first vertical drive mechanism part (3), a holder part holding part (4b) that is connected to the holder part (6) by a second vertical drive mechanism part (5), and a pressure receiving part (4c) that is connected to an other end of the C-frame (4) and accepts the pressure from the welding tool (7); the control device (12) has a first welding mode, and a second welding mode for performing friction stir welding on the basis of a welding command signal, and a second holding position determination signal that corrects a first holding position determination signal such that the depth and range of a weld part are constant in accordance with the state of the pressure receiving part (4c); and the first welding mode and the second welding mode being included in a single weld pass from the insertion of the welding tool (7) into the members (10) to be welded until the withdrawal of the welding tool (7).
