Subject Title: control of electromagnetic and thermal processes in the electrotechnical complex of a contact welding machine. The analysis of the mutual influence of indicators of quality of electricity of the power supply network and technological process of resistance welding. A generalized model of the electrotechnical complex of a resistance welding machine has been developed, which includes input and output parameters, external perturbations and control effects. A method of controlling the welding process with ensuring the stabilization of the electrical thermal process in the welding contact is developed. Power sources for electrotechnological complexes of resistance welding machines with one-phase and three-phase network connection have been developed. The feasibility of the proposed technical solutions was confirmed by conducting experimental studies. The practical significance of the results is to develop methods and systems for controlling the power sources of resistance welding machines that provide high quality welded joints in the presence of external perturbations, as well as circuit solutions and power management systems that meet the standards of electromagnetic compatibility for emission harmonics, provide symmetrical current consumption and have an increased power factor.
