Weld Inspection and Crack Detection with Ultrasound

The newly developed SONOSCAN angle probes of SONOTEC for non-destructive material testing check metals for cracks and inclusions. They are mainly used in the metal industry. The ultrasonic probes are able to detect critical defects as well as quality deficiencies of welds. They are effective ultrasonic converters which compatible with the common mobile ultrasonic testing equipment.

Inside the angle probes there is a transducer which is able to emit ultrasonic transverse waves in a specific angle to the workpart via a forward wedge. Existent material deficiencies can be identified on the basis of the reflection echo. It is possible to adapt to curved surfaces i.e. adaptation to different pipe forms through seat grinding of the probes. Thus the DIN EN 1714 standard regarding non-destructive testing of welds can be well achieved. The unique and benefical ergonomical shape of the angle probes enables a comfortable and a handy usage.

The precise ultrasonic probes are developed and manufactured by SONOTEC in two different types of construction. They can be chosen according to the angle, the frequencies and the size of transducers for different material thickness as well as spatial conditions. There is a possibility to realize customized solutions besides the two mentioned standardized types of construction.
