Özet: In this study, the effect of current and welding time on spot nugget diameter and deformation in KSR (Current controlled) and IQR (adaptive) mode options in resistance spot welding robots with MFDC transformer was investigated. Optimum parameters for KSR and IQR mode were determined to reduce cycle time in resistance spot welding robots. During the study, labour, time and cost were attempted to be minimized by working with the correct parameters. The lowest time for one spot in welding operation increases profitability. In this project, spot weld appearance, nugget diameter measurement and cavity depth within the quality are determined by the specifications of the main industry by making part production trials under mass production conditions. Reference sheet thickness, electrode type and force were kept constant, and spot-welded parts were subjected to the non-destructive test in the resistance spot welding robots under the KSR and IQR mode mass production conditions of the current and welding time values that were determined. The spot weld depth and core diameters of the centers were also measured. In addition, no similar study was found in the literature. With this study, the operation time of the resistance spot welding robots with servo motor has been reduced to a minimum.
