Fluorescent Penetrant Testing
Fluorescent Penetrant Testing is a non-destructive testing method used to detect surface defects in materials. It involves applying a fluorescent dye to the surface of the object being tested. The dye seeps into any cracks or voids, making them visible under ultraviolet light.
After allowing the dye to penetrate, excess material is removed, and a developer is applied. This developer draws out the dye from the defects, creating a visible indication. The results are then examined under UV light, allowing inspectors to identify flaws that could affect the integrity of the material or component.
