Optimization of the value chain.

While air-coupled ultrasound testing methods have only been used in niche applications such as aerospace and aviation in recent decades, this testing method is becoming increasingly important nowadays.

This is primarily due to the possibility of testing without coupling and the associated benefits. Air-coupled ultrasonic testing is mainly used in process control in production chains and is perfectly suited for testing materials and structures composed of composites (laminates and sandwich structures), ceramics, concrete, glass, polymers (plastics), wood and metal. Thus, a wide range of inspection tasks e.g. interface detection, bonding characterization, inhomogeneity detection or the detection of internal discontinuities and inclusions can be covered.

In addition, impurities and damage to materials and test pieces are prevented in the production process, thus eliminating costly cleaning steps. Ultimately, this is accompanied by an increase in effectiveness and quality.

One step ahead.

For highly attenuating materials, the performance of the system is critical. The ultrasonic sensors, the scanning area and the system settings should be flexibly adapted to the test task and the material.

These high expectations are met with the new and modular testing system SONOAIR. With the world’s first air-coupled phased-array UT inspection system SONOAIR we developed a technology that works with up to 4 transmitter and receiver channels with freely configurable square wave burst transmitters as wells as low noise receiving amplifiers. By the help of e.g. SONOSCAN CF400-3E probes the inspection can be conducted closer to the material.

As a result of the smaller focus distance, an improvement in the lateral resolution and a clear gain in sensitivity are thus achieved.

With SONOTEC you are one step ahead.

Materials, compounds and structures :

Applications for air-coupled phased-array ultrasonic testing can be found in the automotive, aircraft, railway or wind power industry. Material Testing is carried out so far by transmission measurement (two-sided). SONOAIR enables also the so-called Pitch-Catch order (one-sided). Here, probes are not placed on different sides of the test object, but on the same side. However, this method is only suitable for certain measuring methods such as e.g. the sheet metal weld inspection.

In these sectors, modern composite materials such as glass or carbon fiber reinforced plastics (CFRP, GFRP and ceramics) are used, but many more can be tested with SONOAIR.
