| Abstract Scope |
Proper shielding gas flow is crucial to the wire-arc additive manufacturing process. Improper shielding of the deposition process can lead to voids in the deposited material, an unstable weld arc, and excessive oxidation of the printed part. Several factors can affect the flow of the shielding gas in wire-arc additive manufacturing including nozzle design, wire stickout, gas flowrate, and the location of the nozzle over the part. Schlieren imaging, a technique that uses mirrors, a point light source, and a knife edge to view air currents, was used to examine the effects of these factors on gas coverage. Images and videos will be presented along with strategies for optimizing gas coverage under various conditions. |
