Dye penetrant inspection, also known as a liquid penetrant inspection or penetrant testing (PT), is a widely applied inspection method used to locate surface-breaking defects in non-porous materials. The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components, the magnetic-particle inspection is often preferred instead for its subsurface detection capability. Penetrant testing is used to detects in casting, forging and welding surfaces, such as hairline cracks, porosity and in- service fatigue cracks. SEAL Aviation is equipped to handle all your NDT penetrant testing needs, no matter where your aircraft or part may be.
