This article discusses the current state of standardization in the Russian Federation in the field of application of ultrasonic testing using a phased array. Attention is drawn to the problem of the lack of national standards (especially terminological), which clearly hinders the active development and implementation of the PA UT method in practice. The basic principles of the classical technology of phased arrays are analyzed. Electronic linear scanning, electronic scanning and combined scanning. Combined scanning has several advantages: a high probability of detecting defects, high scanning speed, quick setup and calibration, quick data analysis and small file size in comparison with conventional sector scanning. Some difficulties were noted when trying to work with classical DGS-curves using the synthetic focusing methods SAFT or FMC / TFM with beam focusing at each image reconstruction point. |
