- ÍtemAnalisis metalografico de probetas obtenidas a partir de un proceso de manufactura aditiva por soldadura por arco (WAAM)(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Ramírez Martínez, Omar Felipe; Corrales Rojas, William Yesid; Gutiérrez Bernal, Jesús Manuel; Hincapié Campos, Williams Steve (Codirector)The following document presents a metallographic analysis of several strands of two specimens obtained by wire arc additive manufacturing (WAAM) for Foundation University the Liberators. The samples obtained by this process were subjected to a preparation process under the standard practice for the preparation, cleaning, and evaluation of corrosion test specimens (ASTM G1), after which the specimens were left with a gloss-mirror finish with the help of a cloth of fine fibers, then, a chemical attack was performed with 3% Nital to reveal its metallographic structure. As a result of the chemical attack, a structural recognition was made using a metallographic microscope (Olympus GX41) which provided us with great information when studying each weld bead, allowing us to identify its metallographic structure in each of the trajectories of the weld bead; Finally, a micro hardness test was carried out using the Future-Tech FM-700 micro hardness tester with a load of 100G with a result in Vickers (HV) in each of the beads, and thus being able to find the differences in microstructure and hardness between each weld bead, which will be shown in the following tables.
