Purpose: The aim of this paper is to show how varying cross section thickness of tested product and calibration sample can depend on results of the residual stress measurements by the Barkhausen Noise method. Design/methodology/approach: The Barkhausen noise parameters as RMS value and total number of Barkhausen pulses in samples with different thickness was measured and compared. Also influence of the frequency and intensity of the magnetization current was analysing. Findings: The significant indirect influence of various cross-section thicknesses on Barkhausen Noise level was pointed. The equations describing influence of the thickness on Barkhausen noise at different magnetization current parameters were found. Research limitations/implications: Also the influence of the differences in width of the calibration sample and tested product was observed but in this research was not analysed. Practical implications: Taking into consideration obtained results lets compensate analytically indirect influence of geometrical factors and magnetization parameters on Barkhausen noise parameters. Originality/value: Original value of this paper is demonstrating significant source of error during residual stress measurements by Barkhausen method. For this moment this fact were not taken into consideration.
