The article considers a mechanism for combining surface temperatures of the closest laser pulse under a discrete laser treatment. It is shown that a minimal transfer of the working surface causes a uniform surface heating within the laser irradiation zone, in addition to slow cooling of the surface outside the laser heating area. This facilitates stabilization of the properties of the working surface and reduction of the residual voltage. A case of the rational mode for the laser treatment of slender parts, such as torque shafts, is also provided.
The article considers a mechanism for temperature distribution within metal surfaces subjected to laser irradiation as well as zones not affected by laser light. It is shown that the growth of the laser heating zone facilitates more even temperature distribution. Under an alternate laser pulse at a shorter distance, the temperature of the surface increases; it is added up to the residual temperature of the previous laser pulse, and then slowly decreases. All this stabilizes the residual voltage within metals.
