Carbon plate nondestructive testing method, device and equipment and storage medium

The invention relates to the technical field of ultrasonic testing, in particular to a carbon plate nondestructive testing method, device and equipment and a storage medium, and the method comprises the following steps: determining horizontal coordinates of wave crests of an interface wave and a bottom wave as t0 and k0 respectively; the abscissa t1 of a first point with the wave height being zero is found backwards from the wave crest of the interface wave, and the abscissa k1 of a first point with the wave height being zero is found forwards from the wave crest of the bottom wave; judging defects in the region (t1, k1) through a wave height threshold value; and judging defects in the areas (t0, t1) and (k1, k0) by judging whether wave crests and energy loss exist or not. According to the method, the range of the defect wave gate is determined by firstly determining the wave crest abscissas of the interface wave and the bottom wave, then the range of the defect wave gate is divided, and dual judgment is perf
