Effect of zinc coating on delay nugget formation in dissimilar DP600-AISI304 welded joints obtained by the resistance spot welding process

Examination on joining of 2 mm thick dissimilar stainless steel plates using resistance spot welding

“…Moreover, the TSS values increased with heat input, which was attributed to the larger nugget diameter at higher heat input. Kalashami et al [33] and Parte et al [11] reported that larger nugget diameter can support higher bearing load. From figure 10, it can be seen that during the tensile shear test, there was a strain hardening in the lap shear configuration up to point 'A' (peak loading point).…”

“…However, welding dissimilar metals is different from welding similar metals due to their distinct mechanical properties, chemical composition, and microstructure. In the RSW process, there is an interaction between the electrical, thermal, metallurgical, and mechanical phenomena, which makes the process more complex [11]. In addition, the welding occurs internally between the joining surfaces and the nugget formation can be controlled by various process parameters of the RSW process such as welding current, electrode force, electrode tip diameter, welding time, material thickness, etc.…”

“…Welding is widely used in various modern industries, including energy, building construction, ships, automobiles, aircraft, petrochemicals, food, nuclear power, and electronics [ [1] , [2] , [3] , [4] ]. To ensure the reliability and safety of built structures, it is crucial to have an efficient quality control process, including detecting and classifying defects.…”
