Dye Penetrant Inspection (DPI)
Dye Penetrant Inspection is like revealing nature’s secrets, utilizing capillary action to draw a dye into the smallest surface openings, highlighting defects with vivid color contrasts.
Based on capillary action, this method uses a dye to identify surface cracks and other discontinuities. The dye, applied to the surface, seeps into any defects and is visible under normal or ultraviolet light. This versatile method can be used on both ferrous and nonferrous materials, making it effective in revealing even the finest flaws. Whether viewed with visible daylight or using fluorescent methods, this technique shines across various materials, spotlighting surface discontinuities such as cracks, seams, and porosity.
