- What it is about:
- Non-destructive testing method that uses penetrant liquids to detect surface discontinuities in materials.
- How it is done:
- A penetrant liquid is applied to the material’s surface, which seeps into discontinuities. The excess liquid is removed, and a developer is applied to make the discontinuities visible.
- Where it applies:
- In the inspection of welds, forged and cast parts, and other industrial components to detect surface cracks, fissures, and porosities.
