Plate automatic flaw detector standard test board and using method thereof

The invention discloses a plate automatic flaw detector standard test board, which relates to the technical field of ultrasonic flaw detection, and comprises a plate body, wherein a plurality of flatbottom holes and a plurality of open grooves are formed in the plate body, and the diameters and depths of the plurality of flat bottom holes are different. The invention further discloses a using method of the plate automatic flaw detector standard test board. The defects on the plate automatic flaw detector standard test board are completely designed, the flaw detection performance of an ultrasonic flaw detector can be truly reflected, and the phenomenon of missing detection of the defects of a steel plate is avoided. 本发明公开了一种板材自动探伤仪标准测试板，涉及超声波探伤技术领域，包括板体，所述板体上开设有若干个平底孔以及若干条开槽，若干个所述平底孔的直径和深度各不相同。本发明还公开了一种板材自动探伤仪标准测试板的使用方法。本发明提供的板材自动探伤仪标准测试板上的缺陷设计完整，可真实反映超声波探伤仪的探伤性能，避免出现钢板缺陷漏探的现象。
