description: This work is devoted to determining the effect of filler flux-cored welding wire on the properties of the resulting welded joints. Tasks that were solved during the study: 1. To do an analysis of the literature containing information about cored wires and their production technology. 2. To conduct a study of the properties of the obtained welded joints, depending on their subsequent heat treatment. 3. To analyze the effect of the composition of cored wire on the mechanical properties of welded joints. 4. To offer recommendations for improving the technology for the production of welding wire. The work was carried out at the TPP OJSC NPO CKTI, where most of the actual material was studied: the results of metallographic analysis and mechanical tests. The development of flux-cored wire production technology was carried out at the Department of Materials Science and Materials Technology SPBPU. The mechanical tests showed that the addition of alloying elements significantly increases the necessary properties of the weld.
