Análisis de la resistencia de la soldadura eléctrica por puntos en la nueva generación de aceros de alta resistencia.

The thesis describes the process of study and selection of the materials, variables of the process in the electrical resistance spot welding, monitoring system and the description of the mechanical test made for measure the mechanical quality of the unions. We want to describe and take control of all the variables of the process to be able to make correlations between the values of the different test (cross tension test and lap shear), which determinate the quality of the union, and the values with we weld. For knowing how is welding the machine, we need to study how can the machine fix the parameters. For measure the variables and verify the process, we need to use several monitoring systems Also, it is described the manufacture process of manufacture a fixture to make the cross tension test.Departamento de Ciencias de los Materiales e Ingeniería Metalúrgica, Expresión Gráfica en la Ingeniería, Ingeniería Cartográfica, Geodesia y Fotogrametría, Ingeniería Mecánica e Ingeniería de los Procesos de FabricaciónGrado en Ingeniería Mecánic
