Abstract: Systems and methods described herein are configured to control welding systems, for example, controlling welding process variables based at least in part on nominal stresses estimated using finite element (FE) algorithms. The systems and methods described herein may be utilized to identify nominal stress in welded structures and components to enable adjustment of welding process variables for the manufacture of subsequent welded structures and components, for example, performed by the same welding system. The systems and methods described herein also allow readily available FE stress results to be utilized in a consistent manner, as well as providing user feedback regarding the accuracy of the nominal stress approximations. Furthermore, the systems and methods described herein are generally faster and less error prone than conventional techniques, and are relatively insensitive to mesh density of the FE stress calculations.
