Research on Acoustic Properties of Artificial Inhomogeneities in Calibration Samples for Ultrasonic Testing of Polyethylene Pipe Welds

This article investigates the acoustic properties of artificial discontinuities in reference specimens for the ultrasonic testing of welded joints in polyethylene pipes. An analysis is conducted on the reflectivity of various materials (air, sand, heat-resistant silicate-based sealant, and aluminum...
