Abstract

The Wire Arc Additive Manufacturing (WAAM) is a technique for 3D printing of metallic pieces. Aluminum alloys are particularly studied due to their good mechanical properties and low weight. In this investigation, structured layer walls were fabricated by reproducing a WAAM process with a GMAW welding equipment adapted to a robotic arm for welding processes. AlMg5Cr alloy was used as a filler metal to deposit layers on the surface of an Aluminum 6061-T6 plate in metal transfer pulsed mode. After the WAAM process, the presence β-Al3Mg2Si hardening phase was found in the samples. This phase is responsible of high mechanical strength in such Aluminum alloy, and its formation is related to the heat flux from the arc. Moreover, a high heat flux value contributes to a low porosity and good homogeneity of the layered structure, thus promoting the increase of the mechanical resistance. The best results were obtained in samples manufactured at 200 A, with a Qnet = 7.22 kJ/s. Specimens for tensile testing were obtained in a horizontal plane (parallel to the direction of the layers) and vertical (perpendicular to the layers’ boundary). The vertical specimens reached up to 267 MPa and they were better than the horizontal specimens because a better distribution of the stress along the layer. In all cases, the predominating failure mechanism was determined as ductile–brittle intergranular.
