Introduction to Ultraviolet Surface Crack Detection Modern non-destructive testing (NDT) heavily relies on ultraviolet (UV) light for surface crack detection. This technique is commonly known as Fluorescent Penetrant Inspection (FPI). It plays a vital role in high-integrity industries. Consequently, with the aid of surface crack detection UV, inspectors can easily find the smallest defects on the surfaces that can affect the safety and performance of materials. What is Surface Crack Detection? Surface crack detection UV refers to identifying irregularities occurring on the material’s surface, which may result in failures if undiscovered. These cracks might be due to manufacturing faults, fatigue, corrosion, or other stressors. The conventional methods may not detect these complex flaws; however, by applying UV-based techniques, their sensitivity can be enhanced. The Role of UV Light in Crack Detection For instance, ultraviolet light, particularly UV-A light, helps to expose cracks located on the surface. It combines with fluorescent penetrants such as dye, making them fluoresce, thus showing the presence of cracks where such penetrants have seeped in. The naked eye can see even very small cracks due to this fluorescence. Fluorescent Penetrant Inspection (FPI) Process Preparation of Surface: The entire content is then thoroughly cleaned to eradicate any ...

What is a UV Flashlight? A UV flashlight for leak detection emits ultraviolet light, which normally falls within the 365nm to 395nm wavelength range.
