Possibilities of Assessment of Residual Stress in Welded Designs

The problems of applying known methods for estimating residual stresses applied to welded structures are considered. The area of the welded joint has features that limit the possibility of applying most of the known methods. A comprehensive methodology is proposed, including several methods based on different physical principles. The technique is characterized by high productivity and low surface damage, while maintaining the reliability of the results obtained.
