Abstract

The invention discloses a probe movement limiting device. A limiting device is arranged between a probe and a weld, so that the probe can keep a set distance a constant during movement, and accurate locating of found defects is facilitated greatly. The problem of instability in manual movement of the probe is solved, and the working efficiency is improved. The ultrasonic phased array tablet detection system can be applied to the detection of specified positions on the weld and a tablet material component. The invention also discloses an ultrasonic phased array tablet detection system applyingthe probe movement limiting device.

Description

technical field [0001] The invention relates to the technical field of ultrasonic detection, in particular to an ultrasonic phased array flat panel detection system and a probe movement limiting device thereof. Background technique [0002] The principle of ultrasonic phased array is similar to that of conventional ultrasonic detection, both of which are based on the principle of pulse reflection method. Compared with conventional ultrasound, the advantages of ultrasonic phased array mainly include the following aspects: [0003] (1) The phased array adopts S-scan, that is, it can have ultrasonic waves from many angles at the same time, which is equivalent to having probes with multiple angles working at the same time, so the phased array does not need sawtooth scanning, just move the probe along the weld, The detection efficiency is higher. Suitable for automated production, and mass production. [0004] (2) Phased array can have focusing function, but conventional ultra...
