This paper researches the influence of zinc coating of galvanized DP600 steel (DP600G) on the nugget development and mechanical properties of dissimilar DP600 - AISI304 welded joints obtained by resistance spot welding process (RSW). The RSW evaluations consisted of determining, from the dynamic resistance curves, the different stages involved in nugget formation. The experimental results showed that the zinc coating on the DP600G steel has a significant influence on the time needed for the start of the nugget formation, two times higher than that used for non-galvanized steel. The expulsion time was delayed by 1.12 times. The presence of Zn in the DP600G/AISI304 welded joints produced smaller nugget diameters compared to the DP600/AISI304 joints for the same experimental conditions, however higher peak failure load values were obtained for the first. The causes of this unusual behavior are also analyzed in this paper.

Este trabajo investiga la influencia del recubrimiento de zinc del acero DP600 (DP600G) en la formación del punto y las las propiedades mecánicas de las uniones disímiles DP600 - AISI304 obtenidas mediante el proceso de soldadura por resistencia eléctrica por puntos (RSW).
El análisis consistió en determinar, a partir de las curvas de resistencia dinámica, las diferentes etapas en la formación del punto. Los resultados experimentales mostraron que el recubrimiento de zinc del acero DP600G influye significativamente en el tiempo necesario para el inicio de la formación del punto, dos veces superior al del acero no galvanizado. El tiempo de la expulsión se retrasó 1,12 veces. La presencia de Zn en las uniones soldadas DP600G/AISI304 produjo diámetros del punto más pequeños en comparación con las uniones DP600/AISI304 para las mismas condiciones experimentales; sin embargo, se obtuvieron valores de carga máxima de fallo más altos para las primeras.
