About DPI

Finding defects in castings, forgings and weldments

This non-destructive testing technique, also known as liquid penetrant inspection (LPI), is a cost-effective method used to locate surface breaking flaws such as cracks, porosity, laps, seams and other surface discontinuities. Dye penetrant inspection can be applied to both ferrous and non-ferrous materials and all non-porous materials (metals, plastics or ceramics), It is commonly used to detect defects in castings, forgings and weldments.

The method is also useful for testing on-site as it is portable, and when applying certain techniques such as visible colour contrast there is no need for additional resources such as electricity or water. This makes it a highly convenient for inspecting surface discontinuities.
