Fluorescent Dye Penetrant Test Results
Photograph - Photograph
Fluorescent dye penetrant test on a metallic component, viewed under ultraviolet (UV) light. This is a form of non-destructive testing in which a dye is smeared onto the component. Excess dye is then wiped off and the part viewed under UV light. This causes it to fluoresce, allowing identification of tiny cracks and other defective areas that would be invisible to the naked eye. The test is performed on non-porous materials, usually non-magnetic metals.
