About Dye Penetrant Testing

Liquid Penetrant inspection is one of the oldest forms of Non Destructive Testing. It is used to locate flaws which are open to the surface. With penetrant testing method, the component  is coated with a visible or fluorescent dye solution and left to soak (dwell). Afterwards the excess dye is removed and the developer, which acts as a blotter, is applied which assists in drawing penetrant out of imperfections open to the surface.
