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
