Non-Destructive Testing (NDT) is a vital process in industries like aerospace, automotive, and manufacturing, ensuring material integrity without causing damage. Among the tools used in NDT, the UV flashlight is indispensable for detecting flaws and verifying processes. What is an NDT UV Flashlight? An NDT UV flashlight is a specialized ultraviolet light tool used in fluorescent inspection processes within non-destructive testing. It emits UV-A light in the wavelength range of 320–400 nanometers, which is ideal for activating fluorescent dyes or coatings applied to materials. When these dyes are exposed to UV light, they fluoresce brightly, revealing cracks, leaks, or other [...]
