FIELD: process engineering.

SUBSTANCE: invention relates to the method of welding materials by high-power radiation sources, e.g. laser, plasma or electron beam, and can be used for welding thin-sheet and diverse materials in various industries. Prior to welding, material edges to be welded are pre-melted. Welding is performed with simultaneous addition of modifiers into melting zone, said modifiers being made up of nanopowders selected from refractory compounds, e.g. nitrides, carbonitrides and oxides. Concentration of nanopowders material makes less than 0.1% by weight of welding bath. Said nanopowders can represent suspensions.

EFFECT: welding of homogeneous and composite materials, higher quality of welded seams.
