  • Process for laser welding resinous members, apparatus for the same and laser-welded resinous product
    Patent number: 8038828
    Abstract: A process is for laser-welding resinous members, and includes the steps of overlapping a transparent resinous member on an absorptive resinous material, and irradiating the transparent resinous member with a laser beam, thereby welding an interface between the transparent resinous member and the absorptive resinous member as a strip shape, wherein the energy of the laser beam acting on a side of a major-curvature-radius curved part of the strip-shaped welded interface and the energy of the laser beam acting on a side of a minor-curvature-radius curved part thereof are averaged.
    Type: Grant
    Filed: February 18, 2009
    Date of Patent: October 18, 2011
    Assignees: Toyota Jidosha Kabushiki Kaisha, Fine Device Co., Ltd., Laser X Company, Ltd.
    Inventors: Masaki Terada, Akihiko Tsuboi, Seijirou Soeda, Jun Hayakawa, Kyouji Kokufuda, Tsuyoshi Tanigaki
