Bruno Debeze has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus for laser welding using a CW laser beam combined with a pulsed laser beam
    Patent number: 7265314
    Abstract: A method for laser welding at least two metal parts, wherein the parts are welded along a weld area, includes simultaneously applying a continuous laser beam and a pulsed laser beam onto the weld area. The action of the pulsed laser is added to that of the continuous laser; with the continuous laser, it is possible to establish a stable molten bath in the weld area, the pulsed laser by its large peak energy, facilitating penetration of the energy and therefore of the molten bath, which allows deeper welding. A device for implementing the method is also disclosed.

  • Method for laser welding of at least two parts and associated devices for applying the method
    Publication number: 20060021976
    Abstract: The invention relates to a method for laser welding of at least two metal parts, wherein the parts are welded along a weld area. The method is characterized by the fact that a continuous laser beam and a pulsed laser beam are simultaneously applied onto the weld area. With the method of the invention, the action of the pulsed laser is added to that of the continuous laser ; with the continuous laser, it is possible to establish a stable molten bath in the weld area, the pulsed laser by its large peak energy, facilitating penetration of the energy and therefore of the molten bath, which allows deeper welding. The invention also relates to a device for implementing the method.
