High frequency sound waves (frequency > 20000 HZ) also known as ultrasonic waves are introduced in a test object through a probe, these waves travel through the material on a predictable path. The waves are reflected at interfaces or other interruptions or discontinuity. The reflected waves are detected and then analysed for the possibility of any discontinuity in the test object. Sound beam is emitted through a probe. The probe….
Radiography testing (RT) is one of the most widely used non destructive test (NDT) method. With the help of this method we can detect hidden flaws or discontinuities present in welds such as cracks, porosity & blow holes, slag, flux or oxide inclusions, lack of fusion, incomplete penetration, Mismatch and tungsten inclusion etc. Short wavelength electromagnetic radiations such as X-rays or Gamma rays (γ) are used for Radiography testing. Both….
Dye Penetrant Test (DPT) is also known as Liquid Penetrant Inspection (LPI) or Penetrent Test (PT). It is one of the most widely used Non Destructive Test (NDT) methods. It can be used to inspect almost all non-porous materials such as metals, plastics, ceramics etc. We can detect any surface discontinuity (or flaw) such as surface cracks, porosity, pinholes etc.by this test method. Principle: DPT is based upon a natural phenomenon….
