| Abstract Scope |
Wire Arc Additive Manufacturing (WAAM) is considered as a promising solution to produce 3D metal printed components due to its higher deposition rate, favourable economical aspects, and the higher influence on the final product Buy-To-Fly (BTF) ratio. This study tackled the effect of controlling the interlayer temperature (IC) using an external cooling system on microstructure and porosity formation of Al-Mg alloys. The cooling system was designed to use gaseous nitrogen as the cooling medium. The results showed that the microstructure of the printed walls using the external cooling (EC) system has equiaxed grains compared to dendritic grains found in the walls printed without cooling with the nitrogen gas, i.e. Natural Cooling (NC). Regarding the porosity formation, the results showed notable reduction the formed porosity in the walls produced with EC compared to samples produced with NC. These findings shed light on the importance of controlling the cooling during WAAM processing. |
