Honami OHARA 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).

  • Laser welding method, method for manufacturing welded body, method for manufacturing electrode for spark plug, and method for manufacturing spark plug
    Patent number: 10201876
    Abstract: Irradiation with a laser beam is started at a welding start position of two members that are stacked together, and the output of the laser beam is set so that spatter is not generated. After the start of the irradiation, the output of the laser beam is gradually increased so that a penetration depth from an irradiated edge to a deeper location between abutting surfaces of the two members falls within a predetermined penetration depth range while the laser beam is not moved. After the output of the laser beam is gradually increased, the laser beam is moved toward a welding end position so that the penetration depth is maintained within the penetration depth range.
