Time-of-flight diffraction ultrasonics (TOFD)
 
 
 
 
  • Measuring the amplitude of reflected signal is a relatively unreliable method of sizing defects because the amplitude strongly depends on the orientation of the crack. Instead of amplitude, TOFD uses the time of flight of an ultrasonic pulse to determine the position and size of a reflector.
  •  
  • In a TOFD system, a pair of ultrasonic probes sits on opposite sides of a weld. One of the probes, the transmitter, emits an ultrasonic pulse that is picked up by the probe on the other side, the receiver. In undamaged pipes, the signals picked up by the receiver probe are from two waves
  •  
  • one that travels along the surface and one that reflects off the far wall. When a crack is present, there is a diffraction of the ultrasonic wave from the tip(s) of the crack. Using the measured time of flight of the pulse, the depth of a crack tips can be calculated automatically by simple trigonometry.
  •  
  • Phased Array + TOFD combination is commonly used to inspect pipeline welds.

This produces a visible indication of defect on the surface of the material. Therefore, the method is most applicable for detecting the surface or sub-surface defects.MT can be applied in various types depending on the applications required. It could be wet, powder or fluorescent.

  •  
  • In Ultrasonic Testing high-frequency sound waves, created by a vibrated crystal in probe, are transmitted into a material to detect imperfections or to locate changes in material properties. The most commonly used ultrasonic testing technique is pulse echo, whereby sound is introduced into a test object and reflections (echoes) from internal imperfections or the part's geometrical surfaces are returned to a receiver.
  •  
  • This method is very sensitive to detect crack type defects but requires extensive training for operator to interpret the result.

This method is an advanced NDT method that is used to detect discontinuities i.e. cracks or flaws and thereby determine component quality. Due to the possibility to control parameters such as beam angle and focal distance, this method is very efficient regarding the defect detection and speed of testing.
