Research on the influence of Welding Head using the process on Welding Performance of Spot Welding Machine

Aiming at alloys commonly used in terminals, this paper studies the method of improving the characterization performance of the spot welding section from the perspective of controlling spot welding process parameters. Using the control experiment, by controlling the welding current, energization time, electrode pressure, and using coolant during welding, the surface structure image and the maximum tensile-shear force curve were obtained, so as to obtain the optimal spot welding process parameters. Then use ANSYS finite element analysis software to simulate the resistance spot welding process, and use the model of the macro morphology, microstructure, hardness distribution, and shear resistance of the spot welding head to verify the optimal welding process parameters of resistance spot welding.
