Dye penetration testing procedure
WebDye Penetration Inspection (DPI), is also known as Penetrant Testing (PT) or Liquid Penetrant Inspection (LPI), is one of the oldest and simplest non-destructive methods … WebDye Liquid Test (DPT) is one of one simple and oldest Non-Destructive Inspection methods. Also, known how the Solid penetration test, the Dye penetrant test is widely previously to detect surface discontinuities like cracks, fractures, porosity, grinding defects, incomplete meld, and flaws include joints.
