MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202617068411 A) filed by Keihin Ramtech Co. , Ltd. on June 01, 2026, for Method For Manufacturing Filet-Joined Component By Using Synchronous Stir-Joining, And Synchronous Stir-Joining Device For Filet Joining.
Inventors include Sato, Ippei; Shibata, Naonori; and Kawashima, Mitsuhiro.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present invention makes it possible to stably perform filet joining while easily and quickly suppressing roughness and disorder in a plastic flow part without requiring an auxiliary tool and with few constraints on joining conditions. This method for manufacturing a filet-joined component is characterized by including a filet joining step for filet-joining two members to be joined, and is characterized in that: the filet joining step is performed by a synchronous stir-joining device; the synchronous stir-joining device is provided with an output shaft, a driving mechanism configured to cause the output shaft to rotate, and a pin portion that is provided to the distal-end side of the output shaft, is configured to rotate due to rotation transmitted from the driving mechanism, and is inserted into the two members to be joined during synchronous stirring; the pin part has play between the output shaft and the pin part, the play enabling vibration of the pin part with respect to the output shaft; the play is a gap or substantially is a gap; the play is configured such that the pin part is free or substantially free with respect to the output shaft within the range of play; and in the filet joining step, the rotating pin part is inserted into the two members to be joined at an inner corner of a corner formed by the two members to be joined, thereby performing filet joining by synchronous stir-joining.
