Resumo: | Laser Directed Energy Deposition (L-DED) is one of the Additive Manufacturing (AM) techniques that has emerged in recent years, and it is one of the disruptive technologies of the Industry 4.0. The selection of welding parameters of the L-DED system is critical for obtaining the desired results in metal deposition, however, due to its intrinsic nonlinear behavior in the process, the suitable choices need to be investigated. In this work it is presented an experimental setup to study the thermal effects on the metal substrate during the process of irradiation. With 40% and 60% of laser beam power, the irradiation results showed only a change in color, but no change in roughness or melting pool was formed. However, with 68% of laser power, a considerable increase of the substrate average temperature with values of more than 100°C at each adjacent track created was observed. The heat affected zone (HAZ) in this sample is expanded in both length and width as the temperature rises due the accumulation of heat during the irradiation process. It is concluded that the temperature of the substrate and other related process variables to be investigated must be controlled to achieve the desired bead formation. |

La selección de los parámetros de soldadura del sistema L-DED es crítica para obtener los resultados deseados en la deposición de metal; sin embargo, debido a su comportamiento intrínseco no lineal en el proceso, es necesario investigar las opciones adecuadas. En este trabajo se presenta un montaje experimental para estudiar los efectos térmicos sobre el sustrato metálico durante el proceso de irradiación. Con 40% y 60% de la potencia del rayo láser, los resultados de la irradiación mostraron solo un cambio de color, pero no se formó ningún cambio en la rugosidad o charco de fusión. Sin embargo, con un 68% de potencia del láser, se observó un aumento considerable de la temperatura media del sustrato con valores superiores a 100°C en cada pista adyacente creada. La zona afectada por el calor (HAZ) en esta muestra se expande tanto en longitud como en ancho a medida que aumenta la temperatura debido a la acumulación de calor durante el proceso de irradiación. Se concluye que la temperatura del sustrato y otras variables relacionadas del proceso a investigar deben controlarse para lograr la formación de perlas deseada.Le dépôt d'énergie dirigé par laser (L-DED) est l'une des techniques de fabrication additive (FA) apparues ces dernières années et l'une des technologies disruptives de l'Industrie 4.0. La sélection des paramètres de soudage du système L-DED est essentielle pour obtenir les résultats souhaités en matière de dépôt de métal. Cependant, en raison de son comportement non linéaire intrinsèque dans le processus, les choix appropriés doivent être étudiés. Dans ce travail, on présente un dispositif expérimental pour étudier les effets thermiques sur le substrat métallique pendant le processus d'irradiation. Avec 40 % et 60 % de la puissance du faisceau laser, les résultats d’irradiation ont montré uniquement un changement de couleur, mais aucun changement de rugosité ni de bain de fusion ne s’est formé. Cependant, avec 68% de puissance laser, une augmentation considérable de la température moyenne du substrat avec des valeurs supérieures à 100°C à chaque piste adjacente créée a été observée. La zone affectée par la chaleur (ZAT) dans cet échantillon s'étend à la fois en longueur et en largeur à mesure que la température augmente en raison de l'accumulation de chaleur pendant le processus d'irradiation. Il est conclu que la température du substrat et d’autres variables de processus associées à étudier doivent être contrôlées pour obtenir la formation de perles souhaitée.Laser Directed Energy Deposition (L-DED) is one of the Additive Manufacturing (AM) techniques that has emerged in recent years, and it is one of the disruptive technologies of the Industry 4.0.
