PT Journal AU Cmorej, D Kascak, L TI Resistance Spot Welding of Transformation- Induced Plasticity Steel RAK 40/70 SO Acta Mechanica Slovaca PY 2021 BP 50 EP 56 VL 25 IS 4 DI 10.21496/ams.2021.014 DE TRIP 40/70; resistant spot welding; tensile test; metallography AB The paper deals with the analysis of the influence of the parameters of resistance spot welding. Resistance spot welding is high-efficiency process for joining metallic materials. The application of resistance spot welding is still the most used joining method for joining the car body parts. The influence of the parameters of resistance spot welding was determined by an experiment. The optimal parameters for achieving the highest load-bearing capacity of joints for the material TRIP40 / 70 with a defined thickness of 0.77 mm were determined. The results of resistance spot welding joints reached the values of load-bearing capacity from 6300N to 9000 N. The exact values parts of the experiment are shown in the paper. ER
