Understanding the Parameters Controlling the Resistance Spot Welding of DP980 Steel

Abstract:

Empirical relationships were developed between the resistance spot welding process parameters (i.e. power, time and electrode force) and quality characteristics (i.e., tensile shear failure load and nugget diameter) of resistance spot welded DP980 steel joints. Further, the process parameters were optimized to get maximum tensile shear failure load and optimum nugget diameter. It is observed that, the electrode force of 4.25 kg/cm², power of 70 kW and welding time of 3.5 sec yielded a maximum tensile shear failure load of 39 kN with an optimum weld nugget diameter of 4.58 mm.
