Abstract Scope |
Heat affected zone (HAZ) microstructure and properties of multipass weldments depend upon multiple thermal cycles. While thermomechanical physical simulations can recreate specific parts of the HAZ, they cannot simulate the full gradient of microstructures present in a real multi-pass HAZ. Furthermore, there can be challenges in achieving realistic thermal cycles and realistic thermal gradients during physical simulations. In this work, we examine the utility of a crossed, bead-on-plate weld (XBOP) together with finite element analysis digital twin to provide a new approach to creating simulated multi-pass welding HAZ microstructures. Select comparisons of simulated microstructures will be made to real multi-pass welding results. |
