The excess penetrant is then removed and a developer applied to draw out the entrant from cracks, to enable a visual inspection of any defects. Accurate interpretation is achieved by our seasoned NDT qualified Penetrant Testing Inspectors, Dye Penetrant Inspection can be used on almost any non-porous material.

The types of defects that can be found with penetrant testing are:

• Rolled Products: Penetrant identifies anomalies (cracks, seams or laminations)
• Castings: cold shuts, hot tears, porosity, blowholes, or shrinkage.
• Forgings: Illuminating cracks, laps, or external bursts.
• Welds: To identify cracks, porosity, undercut, overlap, lack of fusion, or lack of penetration.
