Title: Isao Kawaguchi: Innovator in Welding Technology
Introduction
Isao Kawaguchi is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of welding technology, holding 2 patents that showcase his innovative approach to improving welding methods and apparatuses.
Latest Patents
Kawaguchi's latest patents include a tack welding method and a tack welding apparatus. The tack welding method enhances the strength of a tack-welded joint portion while reducing the height of a reinforcement bead. This method involves tack-welding a part of a joint portion of a first joint and a second joint at predetermined intervals before the main welding process. In this method, a filler metal is supplied to the joint portion, and laser light is deflected and irradiated onto the joint portion. The filler metal is then cut with the laser light to achieve a weld.
His second patent, the hybrid welding device, is designed to minimize the influence of by-products such as spatters, plasma, plumes, and fumes. This device also reduces contamination of the laser optical system and welding defects. The laser head includes a laser nozzle that forms the optical path of a laser beam, along with a series of rectifying plates and air knives that work together to ensure a clean and efficient welding process.
