Abstract
Regularities of structure formation in bimetal material welded joints are generalized. Causes for deterioration of toughness, ductility and technological strength of weld metal are considered. Technological measures to ensure the required service properties and crack resistance of weld metal are specified. Initial data are determined to develop the basic process of welding from one side the NPP piping from clad sheets.
Keywords: arc welding, clad steels, welded joints, brittleness, cracks, carbon diffusion, brittle interlayers, welding technologies
