liquid penetrant inspection

This method involves applying a visible or fluorescent dye to the surface. After application by immersion or spray the dye enters any discontinuities via capillary action. The component is wiped dry and any subsequent seepage from fissures is detected by drawing the liquid out into a white absorbent coating applied after drying off (See Diagrams Below). This method is suitable for any non ferrous components or material that is non absorbent. Typical applications are forged, cast or welded products.
