Weld joint eddy current flaw detection verification test block and manufacturing method thereof

The invention relates to the technical field of flaw detection, in particular to a weld joint eddy current flaw detection check test block which comprises a check test block body, the check test blockbody comprises a base material area, a weld joint area and a plurality of crack structures, and the base material area comprises a first check test block and a second check test block; a first grooveis formed in one side of the first inspection test block, a second groove is formed in one side of the second inspection test block, the weld joint area is arranged between the first groove and the second groove, and the plurality of crack structures are arranged in the weld joint area. According to the invention, the material consistent with the material of the to-be-inspected part is selected as the inspection test block, and the crack structure on the to-be-inspected part is simulated, so that the detection error is greatly reduced, and the accuracy of detection data is higher. 本发明涉及探伤检测技术领域，尤其是涉及的是一种焊缝涡流探伤检测校验试块，包
