Abstract: Abstract We present a numerical simulation of capacitor resistance welding. The model accounts for electrical, thermal and mechanical effects, which are nonlinearly coupled by the balance laws, constitutive equations and boundary conditions. Assuming only plane strains, we develop a two-dimensional FE approximation with simplicial elements, which is especially suited for the simulation of work- pieces with longitudinal projections or thin-walled rings with annular projection. In the melted zone the material is described as an isotropic, electrically conducting thermo-viscoelstic Maxwellian body. In the solid it is assumed to behave nonlinearly thermoelastic.
