Abstract—This article presents the research results aimed at solving the problem of ensuring the hardness of welded surfaces after a machining treatment. Two methods of the thermal friction milling are proposed as a mechanical treatment – a traditional thermal friction milling and a thermal friction milling with a pulse cooling. For the experimental research the planning of experiment was carried out and the necessary number of the carried-out experiments was determined. For a processing were prepared special samples with a welded layer of the welding material, which is used in the production of LLP "Electric locomotive assembly factory" (Nur-Sultan, Kazakhstan). The results of the experimental studies have shown that both methods of the thermal friction milling provide an increase in the hardness of the welded surface. The influence of the milling modes on the hardness of the machined surface was also investigated. Optimal values of the milling modes, which provide an increase in the initial hardness of the machined surface, were established. Simulation of the process of the thermal friction milling modes and analysis of the achieved hardness of the machined surface were performed.
