Title: Seishiro Yoshiwara: Innovator in Metal Processing Technologies

Introduction

Seishiro Yoshiwara is a prominent inventor based in Kitakyushu, Japan. He has made significant contributions to the field of metal processing, holding a total of 10 patents. His innovative approaches have advanced the methods used in producing clad plates and surface-alloying metals.

Latest Patents

One of Yoshiwara's latest patents is a method for producing a clad plate by hot rolling. This method involves a multi-layer structure consisting of a base material, a cladding material, and a cover material. After cleaning the joining surfaces, the cover material is welded to the base material, sealing the cladding material in between. A member for preventing warp is then overlaid on the cover material, and the assembly is hot-rolled to create a blank for rolling. The final product is achieved by cutting and machining the rolled article. Another notable patent involves a method for surface-alloying metal using a high-density energy beam. This technique allows for the alloying of a base metal's surface by locally melting it with a laser or electron beam, while preventing defects through the use of a deoxidizing agent.
