This document describes the ultrasonic detection method of copper and copper alloy bars, including method principle, general requirements, instrumentation and equipment, selection of test types, comparison test blocks, test steps, defect assessment, mass grade, test report. Suitable for ultrasonic testing of round, rectangular, Cube and regular hexagonal copper and copper alloy bars with a diameter of not less than 10 mm by type A pulsed longitudinal wave reflection method. Normative reference documents include qualification and certification of nondestructive inspectors, nondestructive testing terminology Ultrasonic testing, type A pulsed reflection ultrasonic flaw detection (UFD) instrument general technical conditions, ultrasonic flaw detection probe performance test method, etc. Terms and definitions follow GB/T 1 2604.1 - 2020 standards. The principle of the method is to generate high-frequency electrical pulses through ultrasonic flaw detection (UFD) instrument, which are transmitted to the inspected workpiece, and use the reflection signal generated by the reflection body to detect defects, and finally display the depth and size of the defects on the display.
