WAAM process is particularly efficient for high-volume and economical manufacturing of complex geometries. In this work, the advances in modeling of WAAM process for steel will be highlighted combining the modeling of heat source, electromagnetic forces due to ionized gases and computational fluid dynamics based approaches for surface tension driven convection (Marangoni effect) and role of surface active species. The modeling results are validated with the experimental data on temperature measurement and melt pool size. The prediction on melt pool is used to formulate defect model for WAAM process and the electromagnetic force model is used to predict arc wandering in presence of adjacent weld bead. Furthermore, distortion analysis is also carried out in representative components manufactured through WAAM process and validated through experimental data.
