The purpose of the work is to study the processes of controlling the forced transfer of liquid metal during welded wire and ribbon electrodes, the development of calculation dependences of optimization of welded joints, taking into account strength and economy, and the development of universal devices for curving of panels. Methods of research - mathematical modeling, natural laboratory, model test methods, wear resistance. It is established that the hydrostatic pressure is proportional to the tangent of the angle of inclination of the melting plane. The forces of gravitation interact with the forces of surface tension and magnetic. To combine the forces of gravity and magnetic, it is necessary to reverse the magnetic field in a short time. The calculated dependencies of optimization of welded joints, which allow to execute variants of design of welded elements, which meet the requirements of durability and economy, are obtained. The influence of the technology parameters on the probability of pore formation and the ways of increasing the density of the welded metal have been established. It is established that coercive longitudinal fluctuations of the tape electrode ensure its uniform melting, distribution of thermal energy, improving the quality of the deposited layer and energy savings. The basics of designing loose-fitting devices for canvasing of panels have been developed. Requirements for structural elements are established for the purpose of reliable operation. The situation on individual practice of students at enterprises is developed (according to the program "Secondary School of Pedagogical Sciences", 7.5-07: 2018).
