Title: Modeling of electric and heat processes in spot resistance welding of cross-wire steel bars
Keywords: spot resistance welding; contact resistance; coupled electric and thermal eld; 3D FEM modeling

Abstract: The aim of this work is the modeling of coupled electric and heat processes in a system for spot resistance welding of cross-wire reinforced steel bars. The real system geometry, dependences of material properties on the temperature, and changes of contact resistance and released power during thewelding process have been taken into account in the study. The 3D analysis of the coupled AC electric and transient thermal eld distributions is carried out using the nite element method. The novel feature is that the processes are modeled for several successive time stages, corresponding to the change of contact area, related contact resistance, and reduction of the released power, occurring simultaneously with the creation of contact between theworkpieces. The values of contact resistance and power changes have been determined on the basis of preliminary experimental and theoretical investigations. The obtained results present the electric and temperature eld distributions in the system.
