Latest Patents

Takaharu Konishi holds a patent for a method of welding titanium alloy parts with a titanium insert. This method 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 process 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 technique allows for thorough alloying of the inserted titanium with the base metal, resulting in weld metal that is high in both strength and toughness. Additionally, an optional post-welding heat treatment can further enhance the strength of the weld metal.
