Characterization of residual stresses distribution and real structure in thick welded sheets by X-ray diffraction and barkhausen noise analysis after metal active gas and laser welding

Original language description

Generally the manufacturing processes of machine component introduce residual stresses (RS) that have an essential influence on their behaviour during service life. The purpose of this study is to evaluate the residual stress distribution of specimens joined by using high power diode laser and metal active gas (MAG) welding. Non-destructive methods for detection and measurement of RS have been increasingly used in the last few years. The paper outlines the capability of Barkhausen noise analysis (BNA) for evaluation of real structure changes and residual stresses on cross-section of welds due to welding of ferromagnetic plates compared with X-ray diffraction (XRD), that can be used for quantitative analysis of macro and micro level RS separately. However, it is very difficult to use XRD in manufacturing. The principal advantages of BNA over XRD as a tool for RS analysis and real structure characterisation are that it is mobile, faster with more facile carrying out and hence BNA is frequently used for continuous monitoring of RS in industrial processes.
