dye penetrant testing

Dye penetrant testing is a non-destructive method used to detect surface flaws in materials, such as cracks or holes. The process involves applying a dye to the clean surface, allowing it to seep into any imperfections. After a set time, excess dye is removed, and a developer is applied, which draws out the dye from the flaws, making them visible as colored lines or spots. This helps inspectors identify and evaluate surface defects without damaging the object, ensuring safety and integrity in various industrial applications.
