By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-According to news reporting originatin g from Alexandria, Virginia, by NewsRx journalists, a patent by the inventors Na kamura, Keiji (Tokyo, JP), Yajima, Teruhiko (Tokyo, JP), Yokoi, Masahiro (Tokyo, JP), filed on December 13, 2021, was published online on June 4, 2024. The assignee for this patent, patent number 12000695, is Subaru Corporation (Tok yo, Japan). Reporters obtained the following quote from the background information supplied by the inventors: "The disclosure relates to electrode-misalignment detection de vices in resistance welders, and particularly, to a device that detects electrod e misalignment in a resistance welder that joins a plurality of joint members to gether by clamping the joint members and applying pressure and electricity there to. "Resistance welding is favorable as one of joining methods in terms of less dist ortion, good external appearance, and short welding time, and has been widely us ed particularly for manufacturing vehicle bodies in the automotive industry. It is known that resistance welding, also commonly called spot welding, is mainly a chieved by melting joint members using Joule's heat produced in accordance with contact resistance between the joint members. In order to efficiently increase t his Joule's heat, a plurality of (normally two) joint members are pressed and el ectrified while being held between opposing electrodes.
