The object of study - consumable electrode welding process, especially the process and technological effect depending on the control parameters and characteristics of the power supplies and systems to ensure their work. The aim is to improve the quality of arc welding of structural steel by controlling the energy parameters of the process. Among the main research methods used by the basic theory of welding processes, modeling of physical processes. To study the electrical transients applied the theory of electrical circuits. Metallographic examination of welds and weld metal was performed using methods of optical and scanning electron microscopy. Theoretical and practical results and novelty: theoretically and practically proved the possibility of creating a means of active management in the formation of the welding current transients caused by the transfer of electrode metal, submerged arc welding variable symmetric and asymmetric shock when approaching its frequency to the natural frequency of the molten metal bath. The subject and the degree of implementation: developed technology elements pulsed arc welding of carbon structural steel with a pulsed supply of protective gas pulse hybrid laser-arc welding. Developed the current source of the arc on the basis of the original inverter kvazireznansnogo powerful thyristor frequency for submerged arc welding in the frequency range 5 ... 50 Hz.
