Penetrant Inspection

Penetrant testing is a widely applied inspection method used to locate surface-breaking defects in all non-porous materials like metals, plastics, or ceramics. It helps detect casting, forging and welding surface defects as well as leaks in new products, and fatigue cracks on in-service components.

Hi-Tech Metal Finishing offers the following approved penetrant inspection processes for these original equipment manufacturers.
