Ultrasonic Testing

Ultrasonic Testing

  • Ultrasonic Testing services for raw materials, rolled products, casting, forging and welding.
  • Contact testing carried out at client locations and at sites.
  • Digital UT Inspection using with real time recording device, records 50 hours of continuous Ultrasonic Testing for archival purpose. Review is possible on display of UTRD-1 itself or on a PC after simple downloading or on a TV.
  • Immersion testing of smaller thickness components and larger parts with complex shape
  • Ultrasonic thickness measurement services at ambient temperatures and elevated temperatures
  • Ultrasonic Testing of Fabrication/Welded joint inspection.
  • Ultrasonic Testing of Structural joints and pipe joints as per AWS D1.1
  • All UT jobs are carried out using procedures approved by ASNT NDT Level III

Basic Principles:

In ultrasonic testing, high-frequency sound waves 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. Below is an example of shear wave weld inspection. Notice the indication extending to the upper limits of the screen. This indication is produced by sound reflected from a defect within the weld.
