Computational welding mechanics (CWM) is challenging to analyse owing to the thermomechanics and associated effects of microstructural evolution on material behaviour that have to be accounted for. Mastering CWM makes it possible for welded structures to be designed and enables engineers and researchers to simulate many other manufacturing processes that share the same challenges. In this chapter, the physics of welding stresses and distortions and corresponding analysis methods and model simplifications are introduced. Key issues in CWM are heat input models and material modelling, which are given special attention in the final sections
