The problem of general evaluation of technical condition of main longitudinal beams of the E.O. Paton Bridge was considered based on the results of selective non-destructive testing of truss elements. It is shown that the main cause of damage to the elements of the main beams is corrosion of the nodal welded joints in the places of debris accumulation. High quality of welded butt joints made by automatic and semi-automatic submerged arc welding was noted. 10 Ref., 18 Figures.
Keywords: E.O. Paton Bridge, main beams, welded joint, corrosion, non-destructive testing, technical diagnostics, automatic and semi-automatic welding, damage to welded joints
