Title: Keizou Tanaka: Innovator in Welding and Cladding Technologies
Introduction
Keizou Tanaka is a notable inventor based in Saitama, Japan. He has made significant contributions to the fields of welding and cladding technologies. With a total of 3 patents to his name, Tanaka's work has had a considerable impact on manufacturing processes.
Latest Patents
One of Tanaka's latest patents is a method of working press die. This innovation involves a working tool and a cladding device that can be interchangeably mounted on a working head of a working apparatus. Initially, the working tool is attached to the working head to profile a die blank and cut a predetermined portion to form a beveled area. Subsequently, the working tool is replaced with a cladding device to perform cladding on the beveled portion using the required material. Finally, the cladding device is switched back to the working tool to finish the clad portion into a predetermined shape.
Another significant patent by Tanaka addresses the welding material for hard-facing and the method of determining its composition. The hard-facing welding material must lie above a specific line in a Schaeffler's structure diagram, represented by a Cr equivalent and a Ni equivalent. If the base metal is preheated, the carbon precipitation line will be at a Ni equivalent of 34, necessitating the Cr equivalent to be above 4. However, if the Cr equivalent exceeds 4, cracks may occur after welding. To mitigate this issue, Tanaka raised the carbon precipitation line to a Ni equivalent of 38 without preheating the base metal, ensuring the Cr equivalent of the welding material remains at 4 or less.
