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