It is Nobby Tech. Ltd. I display epoch-making laser illumination and high-speed camera for welding visualization. Arc light influenced the visualization of the welding conventionally, and photography was difficult. We deny influence of the arc light, and the laser illumination visualizes a molten pond and the outbreak situation of sputtering precisely. We have the software analyzing flow states of counting of sputtering and the molten pond. We have visualization, solution in the analysis to welding. Thanking you in advance.
