Abstract
Misorientation Changes and Residual Stresses Redistribution after Welding. A Physical Simulation
Highlights
IntroductionMetallurgical processes during welding, such as shrinkage, quenching, and phase transformations, produce residual stresses in different zones of the welded parts
Welding is widely used in the manufacture of steel products
The stress state on the whole is defined as a tensor value, these measurements are sufficient for the aim of this paper to detect the change of the residual stress state on the analyzed areas
Summary
Metallurgical processes during welding, such as shrinkage, quenching, and phase transformations, produce residual stresses in different zones of the welded parts. These residual stresses, tensile stresses, can significantly impact the reliability and the integrity of the welded components. It is important to understand the distribution of the residual stresses on the surface of the welded components in and near the welding zone. Our recent work reports the effect of residual stress redistribution in a relatively short, up to two weeks, period after the welding procedure[1,2,3]. The microstructure analysis rules out the possibility of stress redistribution due to material failure
