Some special features of using DGS (AVG) diagrams during ultrasonic testing of welded joints
Tóm tắt
The results of development of a method and piezoelectric probes with DGS (AVG) diagrams for ultrasonic testing devices are considered. The technique is compatible with European standards for ultrasonic testing of welded joints as regards the parameters of piezoelectric probes and sensitivity tuning taking into account damping of elastic waves. The succession of operations in tuning of devices, ultrasonic testing, and evaluation of the results with DGS (AVG) diagrams is considered.
