Title: Yosuke Tokoro: Innovator in Metal Joining Technologies

Introduction

Yosuke Tokoro is a prominent inventor based in Wako, Japan. He has made significant contributions to the field of metal joining technologies, holding a total of 4 patents. His innovative approaches have advanced the methods used in friction stir welding and dissimilar metal joining.

Latest Patents

One of Tokoro's latest patents is a metal composite and metal joining method. This invention aims to suppress the influence on joining strength of a friction stir welded section due to a tool hole formed when a tool is extracted. The method involves joining two metals through friction stir welding, where an overlapping section in the axial direction is created between a first shaft and a second shaft. In this process, an inscribed section is formed where the shafts contact each other, and a non-inscribed section where they do not. The plate thickness of the second shaft is decreased in the non-inscribed section, allowing for a friction stir welded section to be initiated in the inscribed section and concluded in the non-inscribed section.

Another notable patent by Tokoro is a dissimilar metal joining method. This method includes moving a tool along a first track on an overlapped part where the first metal overlaps the second metal. The tool is rotated around its axis and pressed against the first metal, penetrating it and inserting into the second metal to a specified depth. After completing the first track, the tool transitions to a second track that is parallel to the first, continuing the process of joining the metals.
