<P>PROBLEM TO BE SOLVED: To provide a device for joining different materials that, even if a fine oxide film is interposed between boundary surfaces, relatively easily removes the oxide film from a joined part without applying not so a large heat input, and improves joining strength. <P>SOLUTION: The device includes: an irradiation head 11 disposed to be movable relatively with respect to materials 1, 2 to be joined and irradiating a high-energy beam B to the joined part of the materials to be joined while relatively moving; and a pressure roller disposed backward in the traveling direction of an irradiation point of the high-energy beam by the irradiation head and pressing the joined part after irradiated with the high-energy beam. In the joining device, multiple pressure rollers 13a, 13b are disposed along in the traveling direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
