Title: Mitsuo Fujimoto: Innovator in Friction Stir Spot Welding
Introduction
Mitsuo Fujimoto is a prominent inventor based in Kobe, Japan. He has made significant contributions to the field of welding technology, particularly in friction stir spot welding. With a total of 13 patents to his name, Fujimoto's work has advanced the capabilities and quality of welding processes.
Latest Patents
Fujimoto's latest patents include a friction stir spot welding device and a friction stir spot welding method. The device features a tool driving section that is designed to advance and retract both a pin member and a shoulder member. The tool driving control section regulates the tool driving section to ensure that the absolute value of a tool average position Tx remains minimal. This position Tx is defined by the equation: Ap·Pp + As·Ps = Tx, where Ap and As represent the cross-section areas of the pin and shoulder members, respectively, while Pp and Ps denote their respective press-fit depths. This innovative approach allows for excellent welding quality, particularly in double-acting friction stir spot welding, while effectively preventing or suppressing internal cavity defects.
