Air-Coupled Ultrasonic Inspections

Air-Coupled Ultrasonic Inspections
Compared to conventional NDT methods the advantage of air-coupled ultrasonic inspection is that the inspection can be performed 100 % contact-free. Sensitive materials do not get exposed to coupling liquids such as water, gel or oil.

In addition, complicated cleaning processes become obsolete. Accordingly, this innovative testing method is suited especially for the inspection of modern composite materials as they are used in several industries such as automotive, aerospace, shipbuilding, machine building and sports and leisure goods. T

he applications and structures are highly diverse and can be developed further constantly. Modern inspection solutions have to be flexible in order to keep track with the rapid development of new materials, structures and applications.

Applications

  • Interface detection
  • Homogeneity analysis
  • Bond inspection
  • Delamination testing
  • Detection of internal cracks and inclusions
  • Impact damage inspection
