ULTRASONIC THICKNESS GAUGING

Wall-thickness measurements are often used for maintenance tasks performed on pipelines and in ships. For instance, they serve to detect general erosive corrosion or selective corrosion, cavitation or erosion. Staff carrying out these tasks often have sound knowledge of how to assess the findings thus brought to light without having any further skills or knowledge of ultrasonic testing.

  • Generation of ultrasound, ultrasonic probes and testing devices
  • Device calibration using calibration blocks
  • Fundamentals of perpendicular wave incidence
  • Defects due to corrosion and erosion
  • The use of ultrasound for wall-thickness measurement

 

IMMERSION METHOD

Another way to couple the sound from transducer to a test object is coupling the sound with water. This can be done with squirters where the sound travels through a jet of water or by immersing the transducer and test object in a tank of water. Both techniques are called immersion testing. In immersion testing, the transducer is placed in the water, above the test object, and a beam of sound is projected. The graph of peaks using the immersion method is slightly different. Between the initial pulse and the back wall peaks there will be an additional peak caused by the sound wave going from the water to the test material. This additional peak is called the front wall peak. The ultrasonic tester can be adjusted to ignore the initial pulse peak, so the first peak it will show is the front wall peak. Some energy is lost when the waves hit the test material, so the front wall peak is slightly lower than the peak of the initial pulse.

MANUAL PHASED ARRAY

Ultrasonic phased arrays use a multiple element probe whereby the output pulse from each element is time delayed in such a way so as produce constructive interference at a specific angle and a specific depth. These time delays can be incremented over a range of angles to sweep the beam over the desired angular range. For example, 40 to 75 degree beam sweep would be produced by calculating the time delays to produce constructive interference at 40, 41, 42 …75 degs.

This NDT technology is also referred as Swept Beam Ultrasonic testing. The main advantages of phased array in NDE are:

  • Ability to sweep a range of angles
  • Ability to display the image in real time for the swept angles
  • Ability to focus

TOFD - TIME OF FLIGHT DIFFRACTION

Time of Flight Diffraction (TOFD) method of Ultrasonic inspection is a very sensitive and accurate method for non destructive testing of welds for defects. TOFD originated from tip diffraction techniques. 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 of a reflector.

In a TOFD system, a pair of probes sits on opposite sides of a weld. One of the probes emits an ultrasonic pulse that is picked up by the probe on the other side. In undamaged pipe, 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 tip can be calculated automatically by simple trigonometry. This method is even more reliable than Radiographic testing of a weld.

  • Probe design, sonic field and device engineering
  • Device calibration using standardized calibration blocks
  • Inspection techniques
  • Specimen and flaw analysis

Radiography is a Non Destructive Testing carried out using X-ray generators or artificial Gamma sources.

X-rays or Gamma Rays pass through the object to be radiographed and record an image on a radiographic film, placed on the opposite side.

The quality and amount of radiation reaching the film will be largely determined by the objects thickness and density, e.g. a crack in a weld will increase the amount of radiation falling on the film in that area due to a reduction in thickness. When the film is processed a negative is produced. The thin areas of an object will be darker than the thicker areas, therefore most weld defects will show up dark in relation to the surrounding areas.

Radiography Course contains the:

Basic Radiation Safety (BRS),

Radiographic Interpretation (RI) and,

Radiographic Testing (RT).

Radiography can be used for inspection of welds, castings and wrought materials, in metallic and non metallic materials.

When the film is processed a negative is produced. The thin areas of an object will be darker than the thicker areas, therefore most weld defects will show up dark in relation to the surrounding areas.
