The paper considers the problem of the development of new flux cored wires manufactured from concentrates and waste products of the mining industry of the Far Eastern Region. The authors provide the results of the analysis of the phase and chemical compositions of mineral raw materials, and experimental research. We have developed diagrams that offer a selection of different compositions of charge mixtures depending on the properties demanded from the weld deposited metal. We have also developed a flux cored wire for deposit welding of the automatic coupling locks of the rolling stock that ensures the hardness of the weld metal 500 НВ retaining high parameters of notch toughness (impact strength).
