Latest Patents

Uchiyama holds a patent for a laser welding apparatus, a preventive maintenance method for the internal reactor of a nuclear power plant, and a laser cutting apparatus. The laser welding apparatus features a welding head and a welding head scanning apparatus. A collimating lens installed on the head body of the welding head is positioned opposite the end face of optical fibers. The welding head utilizes only the collimating lens as its lens, resulting in a shortened length. A laser generated by a laser oscillator is introduced into the optical fiber, enters the collimating lens, and is converted into a parallel beam. This parallel beam is then irradiated onto the surface of the welding portion of the object, melting it. Metallic powder is jetted from powder feed paths formed in the head body to the melted portion, allowing for build-up welding on the surface.
