The paper examines various issues related to the state of stress occurring in the connection of graphite electrodes during their lifetime when operating in electric arc furnaces. It also discusses the impact of graphitization process on the electrode strength. Based on the results of numerical calculations supported by experimental studies, the effect on the connection durability of its design and technological process parameters was determined.
