Desarrollo caracterización y procesamiento de materiales solido.

Abstract

The objective of this project was to characterize T-joints welded under the GTAW (Gas Tungsten Arc Welding) process in 3 mm thick flat plates of AISI 430 stainless steel, through finite element analysis. The project was carried out in two linked parts, the first part was the experimental one based on the AWS D1.6 standard, for which the plates were prepared and welded according to the parameters established by the standard for T-joints; Once the joint is obtained, it is subject to evaluation under the acceptance criteria of the standard through a fillet breakage test and macrography; In addition, experimental temperature data were taken in the cord mediations during welding and deformation data once the joint had cooled. The second part of the project was based on Goldak's welding process simulation theory; Therefore, an analysis of thermal and structural finite elements was carried out with the help of ANSYS 2020 software. Finally, the results obtained in the finite element analyzes were validated by comparing them with the experimental data generated in the first part of the project.
