Abstract

Established dissimilar metal iron and nickel resistance spot welding nugget formation temperature field mathematical model for the discretization of the finite difference method, using TFRSW numerical analysis software, data processing module based on MATLAB language, study the dissimilar metal welding nugget formation in the process of resistance spot welding, the size of the develop and change. Put forward the dissimilar conductive metal welding process, the heat transfer effect simulation method and the analysis method of contact resistance. Design the corresponding experiment, verify the correctness of the results of numerical simulation, and analysis in dissimilar metal in the resistance spot welding specification for welding quality are studied.
