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.
