Comparative analysis of structural state of welded joints rails using method of Barkhausen effect and ultrasound

Abstract

To identify the imperfection of technological processes during smelting of rail steel and the subsequent production of rails in modern conditions, traditional methods of research are not enough. Implementation of Barkhausen effect amplitude measurement, residual stresses for defect detection, material structure analysis with the purpose of improving production technology is proposed. Thus, combination of traditional metallographic, mechanical and new research methods that complement and ascertain the requirements of GOST R 51685-2013 can allow conducting fast and accurate analyzes of the conformity of rail steels to GOSTs, and will also determine the causes of rail failure, inconsistencies in technological processes.
