DEVELOPMENT OF THE SCIENTIFIC BASIS FOR THE CREATION OF MULTICOMPONENT COATINGS FROM LOCAL RAW MATERIALS FOR ELECTRODES FOR MANUAL ARC WELDING OF LOW-CARBON AND LOW-ALLOY WELD STEELS

Abstract

The development of welding production accounts for more than 50% of the gross output of the world's largest industrialized countries. Scientific research is underway around the world to predict the chemical composition of welds. In this direction, it is possible to select welding materials that provide the operational characteristics of the metal at the design stage. In this regard, it is important to improve the quality characteristics of the electrodes on the basis of modernization of the composition of the coating shaft to reduce the cost of the electrode. At the same time, in order to improve the characteristics of the welded joint, it is necessary to develop a methodology that allows optimizing the coating composition of welding electrodes, which determines the chemical composition of the molten metal [1,2].
