Ultrasonic Flaw Detection



Ultrasonic Flaw Detection In ultrasonic testing (UT), very short ultrasonic pulse –waves with center frequencies ranging from 0.1 to 15 MHz are transmitted into materials to detect internal flaws or to characterize materials. UT is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites. We offer onsite flaw detection services for inspection of structures, components, welds etc.


We are equipped with state of art digital flaw detectors and our technicians are well qualified, certified for reliable & faster inspection.



Applications:

  • Most weld discontinuities including cracks, slag, lack of fusion, lack of bond, accurate thickness measurement possible
  • To measure intergranular corrosion quantitatively

Advantages:

  • Most sensitive to planar type defects
  • Test results known immediately
  • High penetration capability
  • Requires access from only one surface

Limitations:

  • Surface condition should be suitable for coupling of transducer
  • Coolant (liquid) required
  • Small, thin welds may be difficult to inspect
  • Reference standards are required
  • Requires a relatively skilled operator / inspector, and skilled interpretive personnel
  • Resolution of small defects near surface difficult
