PROBLEM TO BE SOLVED: To provide a method and a device for manufacturing a wide metallic material, by which a strain is excellently suppressed when a large sized panel or the like is manufactured by joining metallic materials. SOLUTION: A friction stir joining of metallic members 5 using a rotating tool 3 is performed in the way that the joined part by the friction stir joining is cooled by ejecting water W from a cooling nozzle 9, the strain is corrected by pressurizing the joined part 5a with a roller 7 after the friction stir joining, further, the metallic members 5 are restricted on a backing jig 1 curved in the reverse direction of the generation of the strain. Thus, the strain which is hardly eliminated only by cooling is excellently eliminated. Further, the water W is saved and also it is prevented that the water W adversely affect a driving system, by blocking the ejected water W with a leakage-prevention wall 11 of coolant and recovering and reusing the water with a circulation pump 13. |
