FIELD: flaw detection of structural members where built-up metal has coarse-grained structure. SUBSTANCE: proposed method is based on use of eddy current for check of large and coarse-grained weld seams, layer by layer in the course of their application. Check is used for austenitic base metals to be welded and/or austenitic built-up metals elevated temperature of up to 350 C. EFFECT: possibility of checking thick-walled and bulky seams. 1 dwg
