Title: Isao Bundou: Innovator in Spot Welding Technology
Introduction
Isao Bundou is a notable inventor based in Saitama-ken, Japan. He has made significant contributions to the field of welding technology, particularly in spot welding methods. With a total of 3 patents to his name, Bundou's innovations have enhanced the quality and efficiency of welding processes.
Latest Patents
One of Bundou's latest patents is a method of controlling the electrode force of a spot welding gun. This invention involves a gun main body operated for equalization by a driving source, a stationary electrode tip that remains immovable, and a movable electrode tip connected to a pressing source. The design ensures that both electrode tips apply an even force to the workpiece, resulting in high-quality spot welding. The driving source is controlled to make the electrode force of the stationary tip to the workpiece nearly zero, eliminating discrepancies in electrode forces.
Another significant patent is an electric resistance welding method that applies unequal force. In this method, when welding a workpiece made of multiple plates of varying thicknesses, the electrode force on the thinner plate side is increased. This adjustment leads to greater contact pressure on the thinner plate, reducing contact resistance and resulting in a smaller nugget on that side compared to the thicker plate.
