- 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.
- ÍtemDesarrollo de un simulador de manufactura aditiva por soldadura por arco (WAAM) para el centro de mecanizado Leadwell V20i de la Fundación Universitaria Los Libertadores(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Poveda Castillo, Yeimy Caterine; García Zaragoza, Ubaldo; Gutiérrez Bernal, Jesús ManuelAdditive manufacturing, for its ability to create three-dimensional parts, providing flexibility, structural integrity and geometric resolution, similar to other conventional manufacturing processes; is positioned among a list of 15 disruptive technologies that achieve relevant change and disrupts the way industries, businesses and consumers operate. This document presents the development of an additive arc welding manufacturing simulator (WAAM) for the Leadwell V20i machining center of the Los Libertadores University Foundation with the help of SprutCAM software. The objective is to strengthen capacities in terms of research, laboratory equipment, and personnel training, providing the students of the institution the possibility of generating autonomy in the manufacture of metal components. Using the methodological approach used, the theoretical parameters on the state of the art of additive manufacturing in specific with arc welding were initially reviewed, allowing a positive approach to the implementation of this technology. The main contributions of the research are framed in the integration of a Lincoln SPEEDTECCC 200C welding equipment to the Leadwell V20i machining center to generate a dual purpose machine which are: subtractive and additive technique, as well as the development of a simulator with the desired parameters that allows to have a preview to the print, resulting in the development of a working methodology that allows the automatic manufacture of parts through the WAAM process and finally an approach to the process from the perspective of non-destructive testing.
