The welding parameters such as welding current and time were determined based on microstructural characterization, microhardness tests and tensile-shear tests. The joints were welded with two parallel welds perpendicular to the tensile-shear test direction. The shunting effect was evaluated based on microhardness and nugget size. A microstructural examination was performed using optical microscopy. The results show that parallel welding increased current diversion along the shunt path, reducing hardness and nugget size in the second weld. Additionally, higher welding current and welding time caused increased hardness and a higher tensile load due to the formation of lath martensite.eninfo:eu-repo/semantics/closedAccessMaterials scienceResistance spot weldingSteel DP600MicrostructureMechanical propertiesNugget sizeDual-phase steelMechanical propertiesTheoretical-analysisMicrostructureJointsOptimizationPerformanceStrengthBehaviorMicrohardnessSpot weldingWeldsLath martensiteMicro-structural characterizationMicrohardness testsMicrostructural examinationNugget sizeTensile shear testWelding parametersShear flowArticle0005184476000132-s2.0-8508198064897103621Materials science, characterization & testingSteel; Spot welds; Dual phase steel
