Ajuste de los Calores de Entrada que se Corresponden con los Tiempos de Enfriamiento de la ZAT en Soldadura GMAW Sobre Acero Dúplex 2205 Empleando la Simulación por Elementos Finitos

Abstract: Resumen En el presente artículo se realiza un ajuste de los calores de entrada que se corresponden con los tiempos de enfriamiento “t12/8” y “t 8/5” de interés, en la ZAT de la soldadura GMAW de una chapa de acero inoxidable dúplex 2205, de 10 mm de espesor, empleando la simulación por elementos finitos. Para la modelación de la soldadura se empleó una metodología desarrollada previamente, la cual se enriqueció con la incorporación de un factor de corrección del calor aportado, a los elementos finitos por los… Show more

“…Two heat inputs were obtained, identified as high heat input (H-HI) and low heat input (L-HI). The numerical value of heat input was obtained considering an 80% efficiency in the welding process, which corresponds to the average value reported by several authors, who refer to a thermal efficiency of the GMAW process between 0.70 and 0.90 [41,42]. Table 5 shows the values of the heat inputs for the two joint configurations, H-HI and L-HI, being 1.24 kJ/mm and 1.04 kJ/mm, respectively.…”

“…However, these simpli cations lead to errors in the HAZ thermal cycle simulation. Numerical simulation methods (e.g., FEM) have been used to overcome these limitations and make the physical simulation more realistic [24][25]. The commercial FEM software Sysweld® was used to accurately describe the CGHAZ and ICCGHAZ thermal cycles.…”
