FIELD : metallurgy.SUBSTANCE : nanocomposite coating including a metal matrix with nanosize particles of metal fluoride and rare earth metals distributed in it is electrolytically applied onto a metal rod of the electrode. The specified coating has the following ratio of volumes of the matrix and nanosize particles, % : metal matrix 55-96, nanosize particles of metal fluoride 3-30, nanosize particles of rare earth metals 1-15. An additional composite coating may be applied onto the surface of the coating, which is made of metal matrix with nanosize particles of metal fluoride distributed in it.EFFECT : welding wire has good welding-technological properties, makes it possible to improve drop transition of electrode metal and mechanical properties of welded connections.2 cl, 1 dwg, 2 tbl
