    摘要: The invention relates to the field of welding. Disclosure is made of a wire comprising a metal body (1) having a longitudinal cavity (3) filled with a charge (2) comprising at least one constituent from the group consisting of alloying and slag-forming constituents.On the surface of the cavity (3) and the wire there is disposed a coat (4, 7) made up of at least two layers (5, 6 and 8, 9). Each of said layers (5, 6 and 8, 9) incorporates one constituent selected from the group consisting of alloying and slag-forming constituents. From 10 to 99 percent of the mass of the constituents in the layers (5, 6) of the coat (4) and in the layers (8, 9) of the coat (7) is disposed on the surface of the cavity (3), and the total area of the layers (5, 6) of the coat (4) and the layers (8, 9) of the coat (7) in cross section of the wire, incorporating the identical constituents, amounts to from 0.001 to 0.1 part of the area of the metal body (1).
