Overview
Welding is a popular method of forming joints between metal components. The most common type is fusion welding, in which a heat source is applied to melt the material before it resolidifies to form the joint. This procedure involves intense heat cycles, responsible for nonlinear material behavior and usually inducing substantial thermal stresses. Following the process of welding, thermal stresses are mostly locked in the material, and therefore, they are termed residual stresses. Residual stresses can often be detrimental to the structural integrity and mechanical performance of a welded component, in which case they ought to be mitigated by performing procedures such as post-weld heat treatment (PWHT). Both numerical and experimental techniques are used to quantify residual stresses in order to predict their effect on the mechanical behavior of the component. At present, one of the most effective methods of determining thermal stresses in welded components is the finite...
