Effect of reheating zones in additive manufacturing by means of electron beam metal wire deposition method

•The heat transfer model required for the study was created and described.•It was determined that during the depositing process, sub-layer temperatures increased continuously.•For quantitative verification of the model an experiment was conducted with a pyrometer.•It is shown that the developed model adequately recreates the temperature time-dependences.•Model can be applied to the study of control processes with feedback.
