Eddy current testing device, manufacturing equipment for steel material, manufacturing equipment for steel pipe, eddy current testing method, steel material manufacturing method, and method of manufacturing steel tube

摘要

Problem to be solved: to provide an eddy current testing device capable of highly probing a seam portion of a steel pipe, a manufacturing facility for steel material, a manufacturing equipment for steel pipes, a method of eddy current testing, a method of manufacturing steel, and a method of manufacturing a steel pipe.The eddy current testing apparatus is a eddy current testing device for eddy current testing for an object to be tested using a probe equipped with excitation Coyle and detection Coyle, and has a probe protecting member covering the side and bottom of the probe. A first cooling medium is filled inside the probe protective member and the probe is cooled by the first cooling medium.Diagram
