The possibility of controlling the impact parameters for improving the quality and reliability of the welded joint of the tube-grid of the heat-exchange apparatus by adjusting the parameters of the discharge circuit of the electrotechnical-logical unit and the angle of cutting the opening of the tube grid is considered. A mathematical model is proposed and simulation is performed to estimate the impact parameters. The results of the simulation showed good agreement with the experimental ones, and the model can be used to calculate the optimum welding regime and improve the quality of the welded joint.
