Ultrasonic Testing


Ultrasonic Non-destructive testing, also known as ultrasonic Testing or simply UT, is a method of characterizing the thickness or internal structure of a test piece through the use of high frequency sound waves. The frequencies, or pitch, used for ultrasonic testing are many times higher than the limit of human hearing, most commonly in the range from 500 KHz to 20 MHz.

Ultrasonic inspection can be used for flaw detection/valuation, dimensional measurements, material characterization, and more. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipe work corrosion.

Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites, albeit with less resolution. It is a form of non-destructive testing used in many industries including aerospace, automotive ,Power and other Oil and Gas sectors.

Detect Flaws Faster and Better with Ultrasonic Testing

Detecting flaws early on is of utmost importance. But you don't want the process to be time consuming or costly.


Benefits at a Glance

  • 1. Quick, highly accurate inspections
  • 2. Finding any flaws or discontinuities, including extremely small ones, in a product
  • 3. No downtime, as with radiation inspection
  • 4. A lead against the competition with a neutral audit seal
  • 5. Reduced risk of company liability with documented safety standards
  • 6. High penetrating power, which allows the detection of flaws deep in the part.
  • 7. High sensitivity, permitting the detection of extremely small flaws.
  • 8. Only one surface need be accessible.
  • 9. Greater accuracy than other nondestructive methods in determining the depth of internal flaws and the thickness of parts with parallel surfaces.
  • 10. Capability of estimating the size, orientation, shape and nature of defects.
  • 11. Nonhazardous to operations or to nearby personnel and has no effect on equipment and materials in the vicinity.
  • 12. Portable and highly automated operation.
