  • 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

  • Laser roll joining method for dissimilar metals and laser roll joining apparatus
    Publication number: 20050230371
    Abstract: An object is to provide a laser roll joining process for dissimilar metals capable of improving the joining strength of a joint by increasing the amount of generation of ductile intermetallic compound and a laser roll joining equipment. A laser roll joining process for dissimilar metals for joining a first metal sheet 3 and a second metal sheet 4 of different materials held in non-contact state by after only the first metal sheet 3 is heated by laser irradiation, pressing a heated portion of the first metal sheet 3 against the second metal sheet 4 with a pressure welding roller 15 so that they are brought into a firm contact with each other and subjected to plastic deformation, wherein a joining portion between the first metal sheet 3 and the second metal sheet 4 is cooled.
