Penetrant Testing (PT) is used to detect surface-breaking defects in both ferrous and non-ferrous metals. It is commonly applied to stainless steel, aluminum, titanium, and finely finished surfaces where surface integrity is critical.
During PT, a visible or fluorescent dye is applied to the weld surface, allowing it to penetrate any cracks, porosity, leaks, or seams. After excess dye is removed, a developer draws the penetrant back to the surface, creating clear, high-contrast indications that reveal defect locations.
PT is ideal for identifying:
This method is easy to apply, highly sensitive, and works on complex geometries. PT supports compliance with AWS and ASME codes and is used widely in aerospace, marine, manufacturing, and general fabrication environments.
