Penetrant Inspection

penetrant_inspectPenetrant inspection is a nondestructive method of detecting surface flaws and defects. Parts are submerged in fluorescent penetrant solution, soaked long enough for the liquid to infiltrate any potential cracks, and then the solution is rinsed off. Fluorescent penetrant will remain in any surface flaws and be discovered through inspection under an ultraviolet light.
