Scientific research is devoted to very important scientific-technological problem, which deals with the development of the scientific-applied foundations of recovering of worn railway wheels. To solve the task and to obtain main results the methods of engineering electrodynamics. Theory of heat conduction and numerical experimental, analytical methods of investigation of electrodynamic and thermodeformation processes, which take place in the system "inductor - metal", "metal - metal" under induction surfacing using the method of filling liquid metal into the preliminary heated basic metal in the technological melting pot. Besides, while carrying out investigations the law of electro-magnetic induction, Lenz-Joule law, surface-effect, proximity effect, ring effect and total current law were used. Algorithms, graphic dependencies and tabular data make possible to find the structural dementions of heating sources (inductors and systems), as well as the current strength needed to recover the rotating bodies operating surfaces, worn metallic wheels in particular, using the method of filling melted metal into the melting pot without experiment, make possible to reduce time and material costs dealing with the development of new technological processes of the cylinder-shape operating surfaces surfacing, have been obtained. The methods of investigation the temperature field before the filling of liquid metal into the melting pot to recover the worn operating surfaces of rotating bodies, which make possible to decrease expenditures for carrying out experiments, to estimate the qualitative factors of the technological process of surfacing of the rotating bodies operating surfaces, worn metal wheels in particular, using the method of filling the melted metal into the melting pot, have been developed/ Experimental set-up, which provides the realization of the developed technological process for industrial application of the induction surfacing of worn operating surfaces of the cylinder-shape rotating bodies, worn metal wheels in particular, using the method filling the molted metal into the melting pot, which are produced patented in Ukraine, have been developed. Key words: recovering, surfacing, melting pot, induction heating, temperature field, electromagnetism, current resonance.
