This work presents research into properties of the surface layer of the C45 steel following the treatment with highly-focused thermal stream utilizing the GTAW method. The remelting of the surface layer of the sample was performed using welding head moving with a constant speed of 200 mm/min with the amperage of the electrical arch ranging from 50 to 300A. The fractographic measurements of the tested fractures were performed using the SEM microscope. A relationship was established between the current amperage and the speed of the movement of the welding head versus the type of the fractures.
