Fluorescent flaw detection is a simple, highly sensitive flaw detection method that can detect extremely fine cracks on the surface of workpieces. Fluorescent flaw detection is a flaw detection method that uses a penetrant containing fluorescent substances to flush the workpiece. After cleaning, the penetrant retained in the defect is adsorbed by the developer and irradiated with an ultraviolet light source to make the fluorescent substance produce visible light with a longer wavelength. The irradiated workpiece surface is observed in a dark room, and the size, position and shape of the defect are judged by the fluorescent image that appears.
