Abstract
Ensuring reliable operation of bridge metal structures requires solving a wide range of issues, in particular, development of new local materials with guaranteed characteristics, which would provide the required durability of bridge structures. Modern requirements to materials for building metal structures and bridges are met by high-strength sparsely-alloyed 06GB, 06G2B steels, which were the base for development of 06G2BDP grade steel of 355…500 MPa strength class with higher resistance to atmospheric corrosion. Application of the corrosion-resistant steel for fabrication of bridge metal structures will allow improvement of their reliability and service life. The work deals with the influence of welding technology parameters on the structure and properties of welded joints of 06G2BDP steel. 11 Ref., 2 Tabl., 9 Fig.
Keywords: bridge metal structures, corrosion-resistant steel, structure, welded joints, welding consumables, mechanical properties
