FIELD: joining of two articles from steels of different chemical compositions by welding, mainly, rail made from high-carbon steel with railroad flog. SUBSTANCE: method includes butt welding with subsequent cooling of weld and adjacent metal of each article. In this case, for article made from austenitic steel, use is made of steel of the following chemical composition, wt.%: carbon, 0.80-2.10; manganese, 16.00-30.00; silicon, 0.10-1.0; nickel, 1.0-7.0; iron, the balance. Cooling of weld and adjacent metal of each article is performed simultaneously and under similar conditions. EFFECT: simplification of process, higher productivity and reliability. 1 tbl
