Ultrasonic testing of the UT

(Ultrasonic)
  • Detection of cracks, laps, delamination, welds, porosity and other defects located in the entire volume of the tested element.
  • Research based on acoustic phenomena (ensuring appropriate acoustic coupling between the head and the material).
  • Intended for testing non-porous materials.
  • The tests are performed during acceptance, production, final or periodic inspection during operation.

Ultrasonic testing belongs to the most frequently used group of non-destructive testing in industrial practice. They allow for the detection of cracks, rolling, delamination, welds, porosity and other defects located in the entire volume of the tested element. UT research uses acoustic phenomena. An important issue is to ensure an appropriate acoustic coupling between the head and the material. For this purpose, coupling agents are used. Special heads emit ultrasonic waves that propagate through the object, giving signals that are permeable or reflected from the surface or unevenness. These waves then return to the head and are processed by a computer connected to the flaw detector. Ultrasonic tests can be performed manually, semi-automatically or automatically. This method is used for testing non-porous materials. UT tests are performed during acceptance, production, final or periodic inspection during operation.
