Modelling of Electric Arc Welding: Arc-Electrode CouplingArc core simulation requires applying extrapolated experimental data as boundary conditions on the electrodes. This limits the applicability. To become independent of experimental input the electrodes need to be included in the arc model. The most critical part is then the interface layer between the electrodes and the arc core.
