• Abstract: Additive manufacturing has been recognized as an alternative manufacturing technique for industrial sustainability by obtaining components with geometry close to the final shape, on-demand production and synthesis of post-processing steps, reducing material waste, manufacturing costs and CO2 emissions. In this sense, the objective of this work was to develop an additive manufacturing component with wire and arc for application in the context of the oil and gas industries. Studies of process parameters and deposition trajectories were carried out, followed by computational simulation, microstructural, mechanical and corrosive characterization. It was concluded that the printed materials presented properties within the standards requirements and properties equivalent or superior to their counterpart manufactured via forging.
