Latest Patents
Matsunaga's latest patents focus on a friction stir welding method and a group of shape members designed for this process. The primary aim of his invention is to provide a method that can be easily applied to friction stir welding, especially when the thickness of face plates varies at different welding portions. His design includes three shape members with two butt joint portions mounted on a jig. The face plates of these shape members differ in thickness, allowing for greater flexibility in welding applications. The protruded height of the projection is greater at the portion where the surface plates being welded are thin, compared to the thicker portions. This innovation facilitates friction stir welding by ensuring that the size and insertion depth of all rotary tools used can remain consistent.
