Non-Destructive Testing with Ultrasound

Ultrasonic testing (UT) is one of the most important non-destructive testing (NDT) methods. Our ultrasonic testing gauges and transducers are mainly used for  thickness measurements, flaw detection, and weld seam testing.

Ultrasonic testing reliably detects voids, inclusions, and other factors that reduce quality and durability. In addition, signs of wear and corrosion on storage tanks, containers, pipes, and pipelines as well as machines and components can be detected quickly and accurately. Thus, ultrasonic testing makes a considerable contribution to quality assurance and to the prevention of accidents.

In addition to conventional UT gauges and probes, SONOTEC has developed an innovative non-contact ultrasonic inspection system. SONOAIR enables contact-free inspections of highly damping materials such as modern fibre composites (GFRP and CFRP), ceramics, honeycomb structures, and many more by means of air-coupled ultrasound.
