Abstract

En este trabajo se realizaron soldaduras de punto utilizando la técnica de fricción-agitación, SFAP, sobre láminas
traslapadas de aleación de aluminio 6063-T5, de 2,8 mm de espesor y un área de traslape de 25,4 mm2. El proceso
de soldadura SFAP se realizó en una fresadora universal en variadas condiciones de velocidad de rotación y tiempo
de sostenimiento; se mantuvieron constantes tanto la velocidad y la profundidad de la penetración; para determinar
las propiedades mecánicas óptimas de dureza y resistencia mecánica; se caracterizaron los puntos de soldadura
mediante ensayos de tensión, barridos de microdureza y análisis metalográfico. Los resultados permitieron
concluir que mediante este proceso de soldadura se pueden obtener soldaduras de puntos con buena apariencia,
sanidad en el área transversal de la unión, resistencia mecánica y además una adecuada homogeneidad, lo que
las hace una alternativa ventajosa frente a los procesos de soldadura convencionales aplicados sobre aluminio.
