Dye Penetrant Testing (PT)
Detection of surface-breaking defects in non-porous materials using fluorescent dye.
Dye Penetrant Testing (PT) is a widely used method for detecting surface-breaking defects in non-porous materials. By applying a fluorescent or visible dye, this technique reveals cracks and imperfections, ensuring thorough inspections and maintaining the integrity of critical components.
PT works on any non-porous material — ferrous or non-ferrous — and is a cost-effective first-line tool for surface defect screening on welds, castings, and forgings.
