Composite electric drive of the welding electrotechnical complex
DOI: 10.21443/1560-9278-2025-28-4/1-509-521
Abstract. The welding process is characterized by complexity and high sensitivity to external influences, which have inertial properties. Inertial parameters in the context of welding determine the dynamic characteristics of the welding system, which affect the stability of the technological process, the quality of the formed joint, and the efficiency of equipment management. They determine the system's response to variations in welding modes, external disturbances, and transient states. To compensate for the described inertia, it has been proposed to introduce a block into the drive control system that takes into account disturbances and works to prevent this process. The electrotechnical complex (welding machine) operating with an additional proactive correction system demonstrates high stability of operating parameters, and also allows solving the problem of stability of the wire electrode departure. The cumulative effect of the introduction of a method for correcting perturbation changes will allow for an increase in welding productivity of up to 10–15 % by reducing defects and subsequent stripping of products (splashes, "glass" and traces of accidental short circuits). Further research should be aimed at improving energy efficiency, ensuring compatibility with Industry 4.0 platforms and the use of artificial intelligence technologies.
