Dye Penetrant Inspection

Dye Penetrant Inspection (DPI / PT)

Dye Penetrant Inspection (DPI) is a non-destructive testing method used to detect surface-breaking defects, including cracks, porosity, corrosion, laps, and bursts.

A key advantage of DPI is its versatility. Unlike other surface inspection methods that are limited to ferromagnetic materials, DPI can be applied to a wide range of materials, making it suitable for both ferrous and non-ferrous components.

DPI remains an effective and reliable inspection technique for components such as:

• Castings

• Forgings

• Machined components

• Welds
