Ultrasonic Steel Weld Testing with Sonotec
Posted:
Ultrasonic testing is one of the most common methods for the non-destructive inspection of materials. One of the biggest advantages of this method is that it does not harm the human operator. Ultrasonic testing uses mechanical vibrations, in the form of ultrasonic waves, to search for internal discontinuities; the working principle is similar to the sonar technology, which was actually the predecessor to ultrasonic flaw detectors. Today, the technique is well established in the industry, having been used since the 1950s.

Weld testing is one of the main application fields of ultrasonic testing. Using ultrasonic flaw detectors, NDT technicians find and characterize discontinuities within the weld that might lead to material or component failure. Ultrasonic weld testing is part of weld quality control and is crucial for ensuring safety in a wide range of industries: for example, it can be instrumental in preventing plane crashes, reactor failures and oil platform explosions.

With the above requirements in mind, it is important that an NDT technician performing ultrasonic testing of welds or other materials has the necessary training and certification. The international standard (ISO 9712:2012 — Qualification and certification of NDT personnel) determines the criteria for the above.
