DP Testing
Dye Penetrant Testing is a non-destructive technique used to identify surface-breaking defects such as cracks, porosity, and seams in non-porous materials. The process involves applying a visible or fluorescent dye to the surface, allowing it to seep into defects, removing excess dye, and then applying a developer to draw out the flaws, making them visible under appropriate lighting. This method is widely used across industries to ensure component integrity without causing damage.
