Dye Penetrant Testing

Penetrant Inspection is used to detect small defects open to surface, which may not be evident by normal Visual Inspection. Liquid Penetrant Inspection is a method that reveals surface breaking flaws by bleed out of a colored or fluorescents dye from the flaw. It can be used on ferrous materials or non-ferrous materials.
