Investigation of residual stresses in high-cycle loaded laser steel welds
Original language description
The paper contains results of a comprehensive experimental programme aimed at an evaluation of residual stresses in and near laser welds of pressure vessels steels using X-ray diffraction technique. Generally, the manufacturing processes of a machine component introduce residual stresses that have an important and may have even essential influence on their behaviour during service life. The goal of this contribution was to find the influence of high-cycle loading on the stresseś relaxation in and near the welds. It has been found that the surface residual stress state is not the most important factor, either positive or negative, but the fatigue life more or less depends on the specific situation and condition of the materials and welds. On the other hand, the fatigue loading test caused the reduction of microdeformation values. The analysis of microstructure changes by X-ray diffraction could be an indicator of the future cracks initialization and their propagation.
