FIELD: metallurgy.
SUBSTANCE: to welding melt (6) through at least one through channel (10) at least one powder welding additive (8) is supplied in form of gas and powder flow (9). Gas and powder flow (9) leaving the through channel (10) is delivered on the welding melt (6) with minimum exit speed 2 m/s. Due to turbulent mixing of the welding additive (8) with welding melt (6) the flow swirls (12) are created.
EFFECT: welded joint in steel plates with coating without weld strength loss due to admixture of basic coating parts.
