Abstract

The invention discloses an ultrasonic inspection device which uses a TR double-crystal composite probe to carry out longitudinal wave ultrasonic scanning so as to find such defects as delamination and slag inclusion and the like in a board, detects the crackles in the board by using a large angle probe and carries out back checking on the delamination and slag inclusion, and a method using the ultrasonic inspection device to carry out fault detection, also provides a reference block for sensitivity adjustment. The ultrasonic inspection device and the fault detection method thereof can effectively prevent unqualified raw materials from entering the product manufacturing process to influence the quality and final service performance of the product, simultaneously, have the characteristics of simple structure, stable process, high production efficiency and low comprehensive manufacturing cost.

Description

technical field [0001] The invention relates to an ultrasonic flaw detection device and a method thereof, in particular to a device and a method for ultrasonic flaw detection of a thin aluminum alloy plate. Background technique [0002] Due to the advantages of simple operation and easy setting of alarm gates, ultrasonic testing technology has been more and more used in the field of pressure equipment manufacturing. It is also an important testing method in the production of aluminum alloy plates. At present, the flaw detection of aluminum plates is generally based on manual flaw detection, which has low efficiency and unreliable flaw detection. my country’s standard for ultrasonic testing of deformed aluminum alloy sheets for pressure equipment stipulates that the detection range is rolled sheets with a thickness equal to or greater than 6mm, and there is no provision for sheets with a thickness below 6mm. At present, there is no similar testing equipment on the market to ...
