Liquid Penetrant Testing and Services
Liquid Penetrant Testing utilizes a penetrating oil to be drawn into surface breaking indications. Capillary action draws the oil into the indications and after a sufficient dwell time, the excess oil is removed, the part is cleaned and a developer is applied to the surface. The developer draws the remaining penetrant from the indications and provides a visible representation of the location and orientation of the indications.
