Title: Tsuneo Kakimi: Innovator in Titanium Alloy Welding and Sheet Metal Shaping
Introduction
Tsuneo Kakimi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of welding and metal shaping, particularly focusing on titanium alloys. With a total of 2 patents, his work has advanced the techniques used in these specialized areas.
Latest Patents
Kakimi's latest patents include a method of welding titanium alloy parts with a titanium insert. This innovative technique involves welding the opposite end surfaces of two titanium alloy parts using high energy-density welding processes such as electron beam welding, laser beam welding, or TIG arc welding. The method is characterized by the insertion of a member made of either practically pure titanium or a Ti-Al binary alloy containing up to 3 Wt % of aluminum. This approach ensures that the weld metal in the joint is high in both strength and toughness, with the potential for further enhancement through post-welding heat treatment.
Another significant patent is the method of shaping sheet metal of inferior formability. This method addresses the challenges posed by sheet metals, particularly titanium alloys, which are difficult to shape. By covering each end face of a blank with a cover plate made of a more formable metal, the shaping process can be conducted more effectively. The covered blank undergoes a series of heating and pressing cycles, which protects it from contamination and reduces the need for excessive thickness.
Career Highlights
Throughout his career, Tsuneo Kakimi has worked with prominent companies such as Nissan Motor Company Limited and Hitachi, Ltd. His experience in these organizations has allowed him to refine his skills and contribute to advancements in metalworking technologies.
