Title:
FRICTION STIR WELDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/188272
Kind Code:
A1
Abstract:
The purpose of the present invention is to implement a friction stir welding device that can achieve appropriate friction stir welding while suppressing wear and breakage of a welding tool. To this end, this friction stir welding device is provided with: a welding tool (1) that is rotated while making contact with a member to be welded and gives rise to a plastic flow phenomenon in the member to be welded; a tool holder (2) that grasps the welding tool (1) and rotates with the welding tool (1); and supply paths (202, 203, 204, 252) formed in the tool holder (2) and supplying a refrigerant to the welding tool (1).
