Welding Electrodes on the Basis of the Graphite Materials

Introduction . In the context of global competition, the high-quality products of the enterprises from the developed countries occupy the leading positions in the world markets, which causes the growth of demand for graphite products. Graphite, due to its unique properties, is used in various industries, including the production of high-temperature furnaces, electrodes for welding and cutting, as well as in battery production technology. The aim of the study is to investigate and analyse the properties of graphite electrodes, their application in welding processes and to evaluate their competitive advantages compared to other types of electrodes. The work is aimed at identifying the features of using graphite electrodes in various industries, such as steelmaking, metallurgy and chemical industry, as well as studying their physical and chemical properties, which make them efficient for the use at high temperatures and in corrosion conditions. Materials and Methods . The research was carried out with reference to the Tazkazgan graphite mine located in the Central Asia. The chemical composition and carbon content of the graphite ore were analysed, which made it possible to classify it into groups by quality. It was found that the ore contains up to 51.8% of graphite and other components that affect its properties. Results. The obtained data show that graphite from the Tazkazgan deposit can be classified by carbon content into low-carbon, medium-carbon and high-carbon, which allows it to be recommended for the production of welding electrodes. The chemical composition of the ore indicates its capacity to be used in various industrial applications. Discussion and Conclusion. Graphite materials mined at the Tazkazgan mine are attributed with the significant quality characteristics, which make them competitive in the market. Further research should focus on optimising processing and application of graphite in new technologies to make the most of its unique properties.
