Penetrant testing is a non-destructive testing method that uses penetrating liquids to reveal surface defects, offering fast, accurate inspection of critical components.
Penetrant testing is a non-destructive testing (NDT) technique in which a colored or fluorescent penetrant liquid is applied to the surface of a material to detect cracks, porosities and other surface defects. This method is widely used in sectors such as aerospace, automotive and energy, where accurate detection of surface imperfections is crucial to guaranteeing the safety and reliability of structures.
After application of the penetrating liquid, a developer is used to make visible any defects that may have absorbed the liquid, enabling rapid and efficient visual inspection. Penetrant testing is particularly appreciated for its simplicity, low cost, and effectiveness in detecting defects in non-porous materials such as metals, plastics and ceramics.
