Laser metal deposition (LMD) is an additive manufacturing process used in manufacturing freeform geometries, repairapplications, coating and surface modification, fabrication of functionally graded materials. It has a broad range of applicationsin various industries, including aviation, space, defence, automotive, tooling, etc. In this work, a multi-physics modelof the LMD process was developed to rapidly predict the geometrical characteristics of the single clad track using the commercialsoftware package Flow-3D. The volume of fluid (VOF) method was integrated to differentiate the interface betweenthe metallic and gaseous cells. To validate the numerical model single bead tracks were deposited, and cross-sections of thebeads were analysed. Mathematical formulae to predict different aspects of the single clad track (height, width, and depth)were derived using regression analysis. The influence of the process parameters on the geometrical characteristics of thesingle clad track was analysed in detail using analysis of variance (ANOVA). Both multi-physics model and mathematicalregression model results were compared to the experimental measurements. The results were in good agreement with theexperimental results.
