Material parts can be separated either mechanically or thermally. During the thermal cutting of the material, the base material is locally melted, burned, or vaporized. The different methods are distinguished by the heat sources that supply them with the necessary energy. The application of the different thermal cutting methods varies depending on the type of material to be cut, its thickness, the resulting desired cut quality, and the overall economic efficiency. This paper deals with the study of temperature cycles formed during thermal cutting of carbon steel of S355 type by oxy-acetylene flame thermal cutting and air plasma cutting. The obtained experimental data are used in the numerical simulation of the thermal cutting process by the given technologies.
