The process includes applying a highly visible liquid, removing the excess, and using a developer to highlight discontinuities. It is essential in construction for inspecting welds, pipelines, and metal structures. #NondestructiveTesting #LiquidPenetrantTesting #WeldInspection #Structures #IndustrialSafety | Architecture & Engineering | Facebook

What is the Principle of Dye Penetrant Testing (DPT)? | Best NDT Institute #ANDT #NDT In this video, we explain the principle of Dye Penetrant Testing (DPT). Learn how liquid penetrants are applied to surfaces, revealing defects like cracks and porosity through capillary action, making them visible for inspection. #DyePenetrantTesting #DPT #NonDestructiveTesting #SurfaceInspection | ANDT - Advanced Institute of Nondestructive Testing & Training | Facebook
