Abstract

The invention discloses a nondestructive detector for implementing detection based on ultrasonic diffraction signals. The nondestructive detector comprises a host and a scanning device; the host is provided with a human-computer interactive hardware platform and connected with a display screen, an operation panel, various electric and data interfaces, a main control computer, an ultrasonic functional module and storage equipment; the scanning device comprises a time of flight diffraction (TOFD) probe, a position coder and a scanning frame, wherein the TOFD probe is a piezoelectric composite probe with wideband narrow pulse special for TOFD detection; the position coder is a high-precision rotary coder and is used for recording the movement position of the TOFD probe during scanning; and the scanning frame is used for fixing the distance of the probe and installing the rotary coder. The probe has the advantages of reasonable structure, good detection performance, small volume and convenience for carrying.
