Abstract
Features of structure formation in the fusion zone of joints on materials of different alloying systems and pertaining to different structural classes are considered in the case of welded joints made on steels using welding consumables. Depending upon the relationship of temperatures of the solidification range TL–TS of the base and weld metal, partial melting of the grains may develop in the fusion zone, its degree being determined by the differences in the values of these temperatures for the combined materials and cooling of the metal in the near-weld zone. The final structure is influenced by the thermodynamic activity of carbon and its redistribution between the weld and base metal, which also depends on the combined material alloying.
Keywords: arc welding, fusion zone, dissimilar and similar joints, solidification ranges, latent melting heat, molten pool, base metal, melting of grains, carbon redistribution
