Abstract Scope |
The wire arc additive manufacturing (WAAM) process is one of the fast emerging metal additive manufacturing techniques. WAAM is known for high deposition rates and relatively lower costs, which makes it suitable for the fabrication of large parts. Heat accumulation is one of the key challenges with WAAM. As layers are deposited during WAAM, heat gets accumulated due to insufficient cooling. This continues as the number of layers increase, which affects the geometry and mechanical performance of the deposited part. In this study, the WAAM process is modelled numerically, and the heat accumulation patterns are analysed. Hotspots are identified during deposition and its effect on part performance is investigated. Further, the effect of inter pass dwell time, number of layers, and deposition path strategy on heat accumulation are studied and the results are discussed. |
