Summary:Title screen
Modeling of the temperature distribution during electric arc surfacing with a strip electrode is carried out in relation to the design scheme of a semi-infinite body. Also, in the work, the temperature distribution was calculated when a flat layer was heated by a linear source, which made it possible to compare the temperature distribution data without and taking into account the heat release conditions at the product boundaries. The simulation results showed that the control of heat input into the base metal when using mechanical control actions makes it possible to reduce the overheating of the weld pool, reduce the area of the melting isotherm, and reduce the cooling rate of the heat-affected zone. By calculation, the previously determined optimal range of values of the frequency of control actions of 40÷60 Hz was confirmed, which makes it possible to ensure the minimum depth of penetration of the base metal and obtain a favorable structure in the heat-affected zone, prone to the formation of a coarse-grained structure
