| Abstract Scope |
Wire-arc directed energy deposition is a technology that uses an electric arc to melt the feedstock wire on a layer-by-layer basis to create 3D structures. Traditionally, toolpaths in wire arc are divided into two subcategories: single track and meander. In this work, we analyze the effect of toolpath selection and meander width have on material properties and cooling rate for parts printed using Inconel 625. The results show that single tracks have a continual cooling period, while meander walls experience reheating caused by the back-and-forth movement of the torch. The wall width is the primary factor influencing the effectiveness of the reheating effect in material property improvement. Correlations between mechanical properties and cooling rates are explored to elucidate the controlling mechanisms. A transition zone is identified where the reheating facilitates complete solidification and modifies the grain structure and mechanical properties. |
