Title: Innovations in Welding Technology: The Contributions of Tomokazu Godai
Introduction
Tomokazu Godai, a notable inventor from Kamakura, Japan, has made significant strides in the field of welding technology. With a portfolio that includes eight patents, Godai has demonstrated his commitment to enhancing the efficiency and effectiveness of welding processes, particularly in stainless steel applications.
Latest Patents
Among his most recent innovations is a composite wire designed for stainless steel welding. This composite wire incorporates a unique flux formulation, consisting of 0.1 to 10% by weight of an anhydrous silicate and 0.01 to 0.75% of a metallic oxide with a melting point below 888°C. This composition aims to improve the performance and reliability of gas-shielded arc welding.
Additionally, Godai has developed a novel welding process. This method involves automatically controlling the arc length between a non-consumable electrode and the base metal during a TIG welding process. This process utilizes magnetic fields generated by DC current to deflect the arc, preventing arc blow and ensuring precision. The current is also pulsated to weave the arc during welding, followed by heat treating the final weld layer, enhancing its quality and strength.
