DYE PENETRANT INSPECTION
The process of wetting the surface of the item under test with a penetrating material (fluorescent or contrast), then removing this material and applying a developing agent that draws the penetrant trapped in surface depressions or void to the surface, where it may be viewed by the inspector.

THE METHODS
Accomplishing dye penetration inspection are wide and varied, depending on the material, type of defects suspected, surface conditions, as well as the applicable specifications.
All these points must be taken into account when determining penetrant materials, dwell times, wash methods, drying time and temperature, development materials and times. Magna Chek has years of experience, trained personnel, and all the materials to meet the most demanding penetrant inspection requirements.

DISPLAYING THE CRACKS
In products such as a casting, cracks are made visible with contrast dye penetrant procedures. Not easily seen by the eye, the contrast dye (and developer) makes the piece and its anomaly visible enough to be photographed under harsh light.

TYPICAL APPLICATIONS
Weldments, castings, forgings, turbine housings, airplane parts, and many non-ferrous metallic materials.
