It is shown that the introduction of micro-sized particles of refractory compounds TiB, ZrB, CeO in the composition of the filler of the composite wire (CW) contributes to an increase in the quality of mass transfer of metal in the welding arc. It was found that under the influence of particles of the considered components, melting components of the CW filler, heterogeneous in terms of thermophysical properties, are more actively formed into a metal drop, and its overheating decreases. This helps to improve the quality of transfer of the electrode metal in the welding arc and to increase the conversion factors of alloying elements into the weld metal.
