Abstract

This invention provides one supersonic phase control array test device, which comprises supersonic phase control array detector, supersonic trigger and receive board, main control board and computer, which comprises the following steps: the supersonic trigger and receive board first generates supersonic wave according to the parameter trigger; supersonic echo signal order is through array element switch circuit, signal amplification adjust circuit, A / D converter, digital echo data from control chip inner memory unit; under control board coordination, the echo data are through data to send high speed data transmission module to personal computer to get test result.

Description

(1) Technical field [0001] The invention relates to a detection instrument, in particular to an ultrasonic phased array detection instrument for automatically detecting weld seams of pipelines. (2) Technical background [0002] In many pipeline construction projects, it is necessary to inspect the welds of large diameter pipelines. After the pipeline is put into use, it is necessary to regularly check the health of the pipeline. The current pipeline detection methods have the disadvantages of limited detection ability, low detection reliability, long detection time, high cost, and radiation detection is harmful to human body. [0003] In the 1980s, Dutch NOVA, TCPL, and other nondestructive testing companies began to develop automatic ultrasonic testing instruments. At the end of the last century, Canadian R / D Tech Company first applied ultrasonic phased array detection to the field of pipeline flaw detection, and produced the PipeWIZARD-PA ultrasonic phased array system s...
