| Abstract Scope |
Additive Manufacturing (AM) offers disruptive potential for manufacturing different industrial components, from prototypes to molds, inserts, and highly complex components such as gas turbine blades. The geometric freedom allows the design of unique characteristics of metallic components, such as weight reduction, incorporating complex conformal cooling channels or meshes, and evaluating the formation of microstructures with functional gradation, adding optimized properties for different regions of the components. This study aims to define the selection of deposition parameters for 5356 aluminum alloy using WAAM via the MIG welding process. Circumscribed Composite Central, CCC DOE with alternative and conventional curt circuit current are proposed. It was observed that the 5356 alloy is sensible using a conventional curt circuit current, with higher splashing and oxide formation. Alternative current reduces the oxidation, stabilizes the metallic transfer, and reduces the substrate dilution. |
