Liquid Penetrant test


A liquid with high surface wetting characteristics is applied to the surface of the part and allowed time to seep into surface breaking defects.

The excess liquid is removed from the surface of the part.

A developer (powder) is applied to pull the trapped penetrant out the defect and spread it on the surface where it can be seen. 

Visual inspection is the final step in the process.  The penetrant used is often loaded with a fluorescent dye and the inspection is done under UV light to increase test sensitivity.
