Aviation & Aerospace - Fluorescent Penetrant Inspection in Non-Destructive Testing

One of the techniques that are used in penetrant testing in NDT is applying the fluorescent dye on the metal surface. Sometimes scratches are similar to cracks to human eyes. It is easy to remove the fluorescent dye from the metal surface if the suspicious marks on the surface are scratches. The dye will penetrate into the cracks after wiping off the extra dye and the rest of the dye inside the cracks can be detected by Ultra Violet light.

Sample for inspection

Black light lamps are the most common equipment for checking fluorescent dye inside the cracks on the metal. However, it is dangerous to human if exposed overtime, and it is not easy to document the cracks or take pictures. Therefore, it is challenging to record the cracks and to do the measurements on the cracks.

Advantages of using X-Loupe

Other than white built-in lighting, X-Loupe also equips with Ultra Violet LEDs (optional for purchasing) for special needs. X-Loupe UV lens can make fluorescent die apparent on the metal surface and allow the users to take pictures of the cracks. Besides, the users are not restrained to observe the cracks in the dark room. They can examine the cracks with the light on or outdoors without affecting the shooting results. The optional X-Loupe Image Management Software is also ideal for users to measure the length of the cracks and make annotations. The multiple designs of X-Loupe enhance the performance of fluorescent testing in non-destructive testing.
