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

Liquid or dye penetrant testing is a non-destructive testing method that uses capillary forces to locate surface-breaking flaws such as cracks, laps and porosity. The flaw must reach the surface in order to be tested, but liquid penetrant testing offers an inexpensive solution for testing large areas quickly. #milling #gaugehow #metalwork #metalcraft #machine #toolmaking #millingmachine #cnc #mechanical #engineering #mechanicalengineering #millingcutter #instagood #tech | GaugeHow
