Advantages of Ultrasonic Testing

A major advantage of Ultrasonic Testing is the fact that the results are far quicker available than for instance X-rays. Our inspector can immediately determine the quality of a joint on the spot. In addition, he can also very accurately indicate where it is located, thus allowing quick repairs. Another advantage: no permits are needed, preventing any production delays as is necessary with X-rays. Our portable equipment also allows us to conduct Ultrasonic Testing at hard-to-reach places.

How does Ultrasonic Testing work?

Ultrasonic Testing applies so-called ultrasound. Its frequency is too high for us to hear. This sound is produced by a detector containing a piezoelectric transducer. A sound wave is sent into a material and reflected by possible defects. This reflected signal is translated by a diagnostic machine, thus identifying any imperfections in the material.

Ultrasonic Testing is used to check all kinds of joints and materials. It is a quick way to determine whether a whether a joint meets requirements or has to be repaired.
