More Information
Summary:A friction stir welding device is provided to uniform the extent of frictional heat applied on the right and left of the welded part based on a welding line by improving the rotational structure of a welding tool. A friction stir welding device(200) comprises: a welding tool(210,240) rotating in order to be friction-contacted with a bonding member; a rotating member(212,242) rotating with the welding tool and having gear teeth at the exterior; a support member(220) in which a rotating member is positioned at an inner through hole and a gear teeth engaging with the gear teeth of the rotating member is formed at the inner surface of the inner through hole; and a rotating shaft member(221) functioning as a rotary center shaft of the support member and being connected to support the rotating member.
