Dye-Penetrant Examination Systems
The dye-penetrant examination system that is the most useful is referred to as the solvent-removable system. This system employs an oil-base penetrant that is removed from the surface of the workpiece with a solvent. Both the penetrant and solvent can be sprayed onto the surface of the workpiece with aerosol cans. The surface of the workpiece must be accessible, but there is essentially no other limitation with regard to size, location, and orientation of the workpiece.
