TWinning Induced Plastisity (TWIP) steels are, new generation high Mn alloyed steels, attractive for the automotive industry due to its outstanding elongation (%40-45) and tensile strength (∼1000MPa). So, TWIP steels provide excellent formability and energy absorption capability. Another required property from the steel sheets is suitability for manufacturing methods such as welding. The use of the steel sheets in the automotive applications inevitably involves welding. Considering that there are 3000-5000 welded spots on a vehicle, it can be interpreted that one of the most important manufacturing method is Resistance Spot Welding (RSW) for the automotive industry. In this study; firstly, TWIP steel sheet were cold rolled to 15% reduction in thickness. Then, the cold rolled TWIP steel sheets were welded with RSW method. The welding parameters (welding current, welding time and electrode force) were optimized for maximizing the peak tensile shear load and minimizing the indentation of the joints using a Taguchi L9 orthogonal array. The effect of welding parameters was also evaluated by examining the signal-to-noise ratio and analysis of variance (ANOVA) results.eninfo:eu-repo/semantics/openAccessEngineeringOperations research & management sciencePhysicsMechanical-propertiesMicrostructureBehaviorSteel sheetAnalysis of variance (ANOVA)AutomobilesAutomotive industryCold rollingEnergy absorptionManganeseManufactureMetal claddingPlasticityResistance weldingShear flowSignal to noise ratioSpot weldingSteelTaguchi methodsTensile strengthWeldingAutomotive applicationsEnergy absorption capabilityL9 orthogonal arraysManufacturing componentsManufacturing methodsResistance spot weldingTaguchi optimizationsWelding parametersProceedings Paper0004113942000102-s2.0-85029600603885Engineering, industrialOperations research & management sciencePhysics, multidisciplinaryManganese Steel; Microstructure; Stacking Fault Energy
