Among the direct energy deposition methods, one of the most energy-efficient is the wire and arc additive manufacturing (WAAM) technique based on metal inert gas welding (MIG-WAAM). The MIG-WAAM technique uses wire and arc to deposit a material layer by layer. The temperature distribution during layer-by-layer deposition in the wire arc additive manufacturing (WAAM) method is influenced by the route planning in the metal deposition process. The quality of the metal deposition and its dimensional precision are influenced by temperature distribution. This study represents the development of a Finite Element Analysis (FEA) based model for the MIG-WAAM process to analyze the impact of temperature distribution on the metal deposition process. Using the MIG-WAAM technique, the proposed model has been utilized to simulate metal deposition of SS304L multilayer rectangular box structures on mild steel substrates. The distribution of temperatures across the material that has been deposited has been observed. The findings demonstrated that temperature concentrations occur at every step in the deposition process, potentially resulting in a decline in deposition quality. To enable smoother and higher-quality metal deposition, the established model may be further utilized to construct a feedback-based temperature control system.
