What Is Liquid Penetrant?
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
