Abstract Scope |
Wire Arc Additive Manufacturing (WAAM) is a relatively low-cost, high throughput additive manufacturing technology that uses arc welding to deposit metal beads in a layer-wise fashion to produce large-scale, complex parts. WAAM toolpathing strategies commonly feature overlapping linear deposition paths, which result in a high number of thermal cycles and internal porosity defects that can reduce final part performance. Traditional arc welding for joining utilizes oscillatory paths to increase productivity and improve mechanical performance of the weld. The use of oscillatory paths in WAAM is underreported in literature; no prior work has explored how oscillatory path geometries effect part quality. This work analyzes the effects of a variety of single-track and multi-layer oscillatory path geometries on the bead geometry, energy input, mechanical performance, and grain structure of Al5Mg produced by WAAM. |
