Title: Innovations of Tatsumi Osuka in Seam-Welding Technology
Introduction
Tatsumi Osuka is a notable inventor based in Fukuyama, Japan. He has made significant contributions to the field of seam-welding technology, holding a total of 5 patents. His work focuses on improving the efficiency and effectiveness of welding processes, particularly in the production of steel pipes.
Latest Patents
One of Osuka's latest patents is a method and apparatus for seam-welding steel pipes. This innovative method involves providing a conductive net-like enclosure tube around a cable that supplies direct electric current to the welding head. The direct electric current is conducted through the enclosure tube and the steel pipe in opposite directions, which helps to minimize the magnetic field created around the net enclosure tube, ultimately producing a welded steel pipe seam.
Another significant patent addresses the prevention of magnetization of pipe blanks during GMA welding. This method utilizes direct electric current supplied to multiple consumable electrodes in tandem, with alternating polarities. By ensuring that the lines of magnetic force produced by the direct electric current cancel each other out, Osuka's technique effectively prevents magnetization of the pipe blank, thereby reducing the risk of magnetic arc blow during the welding process.
