Fluorescent penetrant inspection (FPI) is a non-destructive testing (NDT) method used to detect surface-breaking defects in non-porous materials, such as metals, plastics, and ceramics. This technique is particularly useful for identifying cracks, voids, and other imperfections that can affect the integrity and performance of components.
