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
