Resistive electric contact method for determining residual stresses in parts after mechanical treatment

This article provides an analysis of the resistive electrocontact method of non-destructive testing of residual stresses. Residual stresses in surface layers are among the factors that significantly affect many characteristics that determine the quality of finished products. During operation, steel structures are subjected to force, mechanical, physical and chemical influences, which result in physical wear, deformation and a decrease in bearing capacity. To develop measures to restore the performance of structures, it is necessary to conduct a survey to determine their technical condition.
