LPT LEVEL II INFORMATION

DYE (or) LIQUID PENETRANT TESTING

Dye Penetrant Inspection (DPI) is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.

The penetrant may be applied to all ferrous and non-ferrous materials. It is particularly suitable for the inspection of batch quantities of machined parts and is a cost effective, efficient method of testing for surface breaking discontinuities.

Dye Penetrant Inspection can also be used using fluorescent consumables and ultra-violet black lamps. This is a common technique for the inspection of turbine blades.
