What is Liquid Pentrant testing?
In Liquid Penetrant the test object or material is coated with a visible or fluorescent dye solution. The excess dye is removed from the surface and a developer which acts like a blotter is applied drawing penetrant out of imperfections open to the surface. With visible dyes, the vivid colour contrast between the penetrant and the developer is used. With fluorescent dyes an ultraviolet lamp is used to make the ‘bleed out’ fluoresce brightly allowing the imperfection to be seen readily

Typical Applications
Inspection of Castings
Inspection of Forgings
Inspection of Welds
Inspection of Aerospace Components
