A dye penetrant test involves several key steps. First, a dye penetrant is applied to the surface of the material and allowed to dwell for a specific time, enabling it to seep into any surface cracks or defects. After the dwell time, the excess dye is removed, and a developer is applied, which draws out the penetrant from the flaws, making them visible. Finally, the defects can be inspected under appropriate lighting conditions to assess the integrity of the material.
