Modelo matemático para el análisis del comportamiento térmico en el proceso de soldadura de un acero estructural mediante un software con base en el método de elementos finitos

Abstract: Introducción: Un proceso de soldadura para unir dos piezas de trabajo con la presencia de un arco eléctrico está ligado a un sistema dinámico representado por la interacción de dos ecuaciones de gobierno. Objetivos: el objetivo general de esta investigación fue desarrollar un modelo matemático para el análisis del comportamiento térmico en el proceso de soldadura por arco eléctrico GMAW de un acero estructural. Metodología: haciéndose una investigación del tipo propositiva descriptiva, con un alcance descripti… Show more

“…As long as the temperature field in the melt pool, melting zone, heat affected zone, and weld pool is impossible to obtain in experiments, it will be necessary to use the heat source models to determine the temperature profile. Therefore, it does not matter that the Goldak model has been used by many authors since 1984 (Xu et al, 2011;De Freitas Teixeira et al, 2014;Nezamdost et al, 2016;Chen et al, 2018;Nguyen and Chujutalli, 2021;Kiran et al, 2022;Villacís Ramón and Yaulema Castaneda, 2022). This model, with a double Gaussian ellipsoid distribution, is the one that best fits the weld pool.…”
