Abstract
Comparative experimental studies have been carried out on the influence of the type and particle size distribution of the original
metal granulated materials, which were used as a flux-cored wire charge, on its welding and technological properties during
submerged arc surfacing. High-speed steel powder PG-R6M5 with 50‒300 μm and 200‒250 μm granulation, obtained by
spraying of a melt metal, was used as a charge for experimental wires. The standard was flux-cored wire, the charge of which
consists of ferroalloys with 50‒300 μm granulation, calculated to ensure a similar chemical composition of the deposited
metal and manufactured using standard technology. It has been experimentally determined that the welding and technological
properties of three types of wires are at a high level, while the surfacing process with flux-cored wires, the charge of which contains
granulated powder PG-R6M5, is characterized by greater stability, which results in an increase in melting and surfacing
coefficients, and a decrease in the loss coefficient, compared to analogue wire with a charge of ferroalloy powders. It was also
determined that the content of harmful impurities in the sample deposited with experimental wires with a charge of granulated
powders is lower than in the standard sample. The patterns noted above indicate that the use of granulated powder in a fluxcored
wire charge is not only technically feasible, but also leads to an increase in flux-cored wire homogeneity, which has a
positive effect on their welding and technological properties.
