SONOAIR Inspection of honey comb struture by through transmission

Air-coupled Ultrasonic Inspections

Compared to conventional contact nondestructive testing methods the advantage of air-coupling is that the inspection can be performed 100 % contact-free. Sensitive materials do not get exposed to couplant 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, ship building, machine building and sports and leisure goods. The 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. More than 25 years of experience, a close connection to a large amount of network partners in research and science, a strong R&D department and a flexible in-house production make SONOTEC a competent partner for the realization of your testing application.
