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.

The Influence of the Welding Energy on the Residual Stress and Magnetic Properties of Steel AISI 444 Welded by the RSW ProcessAbstract: Ferritic stainless steel has been gaining space in the industry, due mainly to its durability and applicability. In recent years, the growing technological advances of the metalworking industry, enabled the development of new alloys and welding processes of this metal. In the midst of these processes, resistance spot welding has been largely used due to the very short process time with low cost. Although there is a lack of available information in the literature, the union of materials by the mixture of the simultaneous action of heat and deformation, present in the resistance spot welding, can affects the mechanical and magnetic properties directly of ferritic stainless steels. Thus, an evaluation of these characteristics in manufactured products becomes important in certain industrial sectors, especially in electronic and metrological equipment. The main objective of this article is the observation of residual stresses and magnetic properties at different levels of welding energy and deformation in the resistance spot welding process steel AISI 444. The results showed that welding and deformation energy affect magnetic properties, on the other hand there is no substantial influence on the residual stress.

“…The failure mode of spot welds, as an important qualitative measure for joint energy absorption during failure, depends on several factors including weld physical attributes, weld metallurgical characteristics as well as the loading condition [60][61][62][63][64]. Three fracture paths can be identified for Al/steel RSW:…”

Dissimilar joining of aluminium and steel, especially using resistance spot welding as a critical process in vehicle manufacturing, is a key challenge for multi-materials lightweight design strategy. Controlling the formation and growth of Al 5 Fe 2 intermetallic is the outstanding issue for producing high strength crash-resistance Al/steel dissimilar resistance spot welds. This critical assessment highlights the current understating regarding factors affecting the joint properties and approaches to control the interfacial reaction. Finally, the unresolved scientific challenges are discussed with the goal of shedding light on the path forward to produce reliable metallurgical bonding between aluminium and steels for automotive application.
