Residual stresses and distortion of components due to welding can signifi cantly influence the components’ functionality and lifetime. The stresses affect the calculation of the static strength of the structure as well as the assessment of fatigue, wearing and crack corrosion behavior. Therefore, the determination of residual welding stresses as well as respective process optimizations are an essential step for ensuring the components’ safety and stability.


Numerical simulation of welding processes is an effective tool for detailed planning and optimizing of welding 
Residual stress and distortion in structures caused by welding can be calculated by means of numerical simulation based on the finite element (FE) method. The impact of welding on the residual stresses of the component can be determined fast and cost-efficiently compared to experimental test arrangements. Consequently, FE calculations are the perfect tool for optimizing pending welding as well as for evaluating already performed welding.
