Abstract: La presente investigación aborda la predicción de deformaciones y tensiones residuales en la manufactura de juntas soldadas utilizando técnicas de soldadura GMAW y GTAW. Se estudiaron juntas entre aceros similares y disímiles, observando que las deformaciones residuales disminuyen con la distancia del cordón de soldadura. Los resultados confirmaron que las diferencias en las propiedades de los materiales disímiles resultan en mayores concentraciones de deformaciones residuales. Además, se evaluaron los esfuerzos residuales, encontrando que, tanto en juntas similares como disímiles, los esfuerzos residuales son más elevados cerca del cordón de soldadura y disminuyen con la distancia. Las juntas disímiles presentaron mayores esfuerzos residuales debido a las diferencias en conductividad y expansión térmica entre los materiales. Se proponen recomendaciones para mitigar estos efectos y mejorar la calidad de las juntas soldadas, incluyendo técnicas de pre-calentamiento y post-enfriamiento, simulaciones térmicas detalladas, y la utilización de materiales de soldadura compatibles. Estos hallazgos son consistentes con estudios previos y ofrecen nuevas perspectivas para la mejora de la integridad estructural de las juntas soldadas en diversas aplicaciones industriales.
This research addresses the prediction of deformations and residual stresses in the manufacturing of welded joints using GMAW and GTAW welding techniques. It studies joints between similar and dissimilar steels, observing that residual deformations decrease with the distance from the weld bead. The results confirm that differences in the properties of dissimilar materials result in higher concentrations of residual deformations. Additionally, residual stresses were evaluated, showing that both similar and dissimilar joints have higher residual stresses near the weld bead, which decrease with distance. Dissimilar joints exhibited higher residual stresses due to differences in thermal conductivity and expansion between the materials. Recommendations are proposed to mitigate these effects and improve the quality of welded joints, including pre-heating and postcooling techniques, detailed thermal simulations, and the use of compatible welding materials. These findings are consistent with previous studies and offer new insights for improving the structural integrity of welded joints in various industrial applications.
