Case Study - Benefits of Using Developer During Liquid Penetrant Inspection


October 2016

Our customer is a manufacturer of heat exchangers for the automotive sector. They wished to inspect aluminium plate used for radiator assemblies; specifically, to detect tiny holes – caused by corrosion – that were penetrating through the aluminium plate.

Our penetrants are widely used for the detection of surface-breaking defects. Where the defects are particularly small, the use of a penetrant alone can make them difficult to see with the naked eye. The purpose of a developer is to effectively pull the penetrant back out of a defect to allow it to be seen by an inspector. The action of pulling it back to the surface also allows the penetrant to spread along the surface around the defect, thus magnifying the strength of the indication.
