The results of studying the properties of flux-cored wires with a metal core are considered, which were used as a base
for suggesting approaches to development of compositions of flux-cored wires for gas-shielded arc welding of joints of
low-alloy steels of higher and high strength. Application of dynamic thermal analysis of powder mixtures that model
the wire cores, enabled obtaining information on kinetics of the processes which develop at heating and melting of fluxcored
wire compositions that allows optimizing the core compositions. Recommendations were elaborated on selection
and application of flux-cored wires for welding low-alloy high-strength steels. 10 Ref., 2 Tables, 3 Figures.
