Abstract
New electrodes of ANV-70BG grade were developed. Relationship of structural and chemical inhomogeneity in transition zone between low-carbon steel and highly-alloyed deposited metal depending on type of the latter and value of welding current was investigated. 4 Ref., 4 Tables, 3 Figures.
 
 
Keywords: coated-electrode manual arc surfacing, low-carbon steel, highly-alloyed deposited metal, transition zone, structural and chemical inhomogeneity, cracks, corrosion
