Abstract: This study presents the results of a computer simulation study of thermal processes in low-carbon Manual Metal Arc (MMA) hardfacing plates with E DUR600. The problems related to the thermal processes occurring during the heating of sheets of steel DD11, manual metal arc hardfacing with electrodes E DUR600, by examining the influence of temperatures, the heating time and the geometry of the test plates. By computer simulation using SolidWorks software, which have Finite Element Analysis (FEA) engineering systems resulting in simulations of temperature distribution over time and the direction of heat fluxes in the thermal influence zone after the MMA hardfacing process.The method aims to increase the exploitation qualities of the treated surfaces, which in turn leads to the need for experimental study of the heat processes occurring in the process of heating, retention and cooling.Based on the comparison of the theoretical and experimental study in MMA hardfacing of plates, it can be concluded that simulation studies through the mathematical model adequately represent the processes of distribution of the thermal field in depth of the real object.
