In TIG welding, the flow of shielding gas that protects the weld area from the atmosphere plays a crucial role in ensuring stable welding quality. In this article, Dr. Reiji Tamaki from Daihen Corporation explains the physical and quantitative relationship between the flow of shielding gas and welding current in TIG welding. During welding, complex phenomena such as arcs and gas flows occur, which are difficult to grasp visually. Visualizing and quantitatively evaluating these phenomena contributes to a better understanding of the welding process and improvements in quality. Observing high-speed phenomena with high-speed cameras plays an important role in the research and development of welding technology and phenomenon analysis.
