Estudio y caracterización de la soldabilidad en materiales disímiles aluminio (6061) – latón (C38500) mediante el proceso de soldadura por fricción

Abstract

The direct drive friction welding is a little applied process to industrial level, especially for the union of dissimilar materials as the case of aluminum-brass This project aims at the study and characterization of the weldability of 6061 aluminum - C38500 brass through tensile tests, microhardness and metallographic analysis, the obtained results allowed to know the mechanical behavior of the weld, the microstructure and the different zones present in the joint. The specimens were divided into 4 groups, varying the design of the joint and the preheating temperature, after performing the tests corresponding to the welded joints, it was determined that the most optimal results are simple joints without preheating, having a percentage value of 95,18% in its average tensile strength compared to the strength of aluminum (233 MPa), while the lowest values occur in the specimens with groove joint and preheating.
