PROBLEM TO BE SOLVED: To install a cooling nozzle capable of changing an ejection direction of gas for cooling the outer circumferential side of a friction stir welding tool.SOLUTION: A friction stir welding device is provided with: a frame longer than the length of a welding line on which works are welded; a pair of work fastening surface plate disposed on an upper surface of the frame so as to form a gap extended along the welding line between the works; a welding device main body including a friction stir welding tool which is located below the gap and is protruded upward from the gap, a main shaft which has the friction stir welding tool provided on the upper end part and a main shaft rotation driving device which turns the main shaft; a linear guide mechanism which supports the welding device main body freely movably along the gap; and a movement device which moves the welding device main body along the gap. The friction stir welding device further includes an elastomer which supports the friction stir welding tool between the friction stir welding tool and the main shaft. |
