Özet
In this study, it was aimed to determine the effect of welding time on tensile shear load, elongation, nugget diameter and indentation depth of triple welded sheet joints by resistance spot welding (FEP05 sheet + FE 600 DP sheet + FEP05 sheet). The thicknesses of FE 600 DP and FEP05 steel sheets were 2 mm and 0.7 mm, respectively. In the welding processes, welding time was increased from 18 cycles to 36 cycles with three cycles increments and resistance spot welding operations were carried out successfully. When the welding time values were increased from 18 cycles to 36 cycles, tensile shear load slightly decreased. The indentation depth increased almost linearly. Also, with the increase of welding time up to 27 cycles, the nugget diameter increased and the elongation decreased, then over 27 cycles, the nugget diameter decreased and elongation value increased.
