Description

(1) Technical field [0001] The invention relates to ultrasonic detection technology, in particular to a portable ultrasonic phased array detection imager. (2) Background technology [0002] Although the existing ultrasonic testing technology has been widely used in various sectors of industrial production as a mature non-destructive testing technology, the current ultrasonic testing method still has the following problems: complex operation and inconvenient use. Most of the existing industrial flaw detectors are single-probe flaw detectors. In order to comprehensively inspect the workpiece, it must be scanned manually or mechanically; the manual operation of single-probe ultrasonic is labor-intensive, and the mechanical scanning device is complicated, and it is difficult to detect complex shapes. The workpiece is powerless and the detection reliability is poor. The single-probe flaw detector cannot perform real-time scanning and detailed inspection of the inside of the work...
