Temperature Distribution in the “Material-Coating” Interface from a Fast-Moving Heat Emission Source for Electromagnetic Surfacing

During simulation of the surfacing process, it is proposed to present the heat emission source in the form of the system of instantaneous point sources flickering for some time; and the period between flashes tends to zero. The final results of the temperature distribution are determined by summing the solitary impacts according to the proposed computational pattern. The obtained characteristics and analytical curves allow presenting, at a first approximation, the value and intensity of the temperature fields in the working zone during the electromagnetic surfacing of the large size blanks with sufficient heat removal from the restored surface. The proposed method may be applied for repair and modernization of the railway vehicles elements.
