RESEARCH ON OBTAINING TUBULAR RODS TYPE Fe-25% Cr-4% W-Ti-La USED FOR CLADDING

The paper presents research carried out for new materials for flame cladding or WIG welding. These materials contain layers with low dilution and high resistance to abrasion and corrosion combined with intense thermomechanical shock. In the first part of the research the tests for the composite core recipe are presented. This core is formed from powders of ferroalloys and protective elements against heating when they pass through the electric arc. The results obtained in this stage are: hollow rods prescription product and the specific characteristics of their manufacturing process in terms of using.
