Title: Tsuneo Shinada: Innovator in Welding Technology
Introduction
Tsuneo Shinada is a notable inventor based in Yokosuka, Japan. He has made significant contributions to the field of welding technology, holding a total of 3 patents. His innovative approaches have advanced the methods and apparatus used in welding processes.
Latest Patents
One of his latest patents is the "Pulsed Arc Welding Method and Apparatus." This invention includes a short circuit detecting circuit that identifies the duration of a short circuit occurring between a consumable electrode and a base metal. It features a comparison circuit that evaluates the integrated or mean value of the short circuit time against a set value. A control circuit then adjusts the supply time of the pulse current and base current based on this comparison, effectively controlling the arc length.
Another significant patent is the "Consumable-Electrode AC Gas Shield Arc Welding Method and Apparatus." This method applies alternating current across a consumable electrode and a base metal. It operates in three distinct periods, adjusting the current levels to maintain optimal welding conditions. If the arc voltage drops below a predetermined threshold during the first period, the system compensates by increasing the current until the voltage is restored.
