Özet

In order to simulate automotive manufacturing conditions, the spot weldability of cold-deformed, in tension by 10%, TRIP800 steels was investigated in this study. Tensile shear strength and failure mode associated with button geometry and electrode indentations were also evaluated, and weld lobe was drawn for resistance spot-welded deformed TRIP800 steel. The microstructure of the weldment was evaluated and the hardness profile of the weldment was also determined. It was found that the properties of the weldment are directly related to parameters used for the process and deformation of base metal prior to welding. It was found that the button diameter and button size ratio of deformed TRIP800 steel spot welds should be at least 4t and 0.14-0.30, respectively, for pullout failure mode, acceptable shear strength, and surface quality.
