Dye Penetrant Test (PT)

Another cost-efficient for wider range of meterials, Qualitech has Dye Penetrant Test for it. The method is conducted by covering the item with a penetrating liquid, which is drawn into the discontinuity by capillary action. After removal of excess penetrant the discontinuity is made visible by application of a developer. It can inspect either color contrast or fluorescent systems.


Dye Penetrant Test is used to locate surface discontinuity such as cracks, seams, laps, cold shuts, laminations, and porosity which opens to the surface in non-porous material. This method can be applied to ferrous or non-ferrous materials. With aforementioned range of materials available for Dye Penetrant Test, it leads to continuous popularity of the method so far
