Liquid Penetrant (PT)
As an industry applied and economically beneficial system, our inspectors perform liquid penetrant testing to locate surface-breaking defects in non-porous materials.
The penetrant is applied to material, although for ferrous components, magnetic-particle inspection is often used instead for its subsurface detection capability.
Liquid penetrant is applied to detect casting, forging and welding surface defects such as surface porosity, hairline cracks, leaks in new products, and fatigue cracks on components in service.
We offer a variety of LPT procedures including visible, fluorescent, water washable, and solvent removable processes to meet our customers’ specific needs
