Fabrication of 12.2 M Span Bridge Girders for Central Railway by Automatic Submerged Arc Welding Process

Abstract

More than 15000 bridges of different lengths span the rivers, over the Indian Railways. About 350 important bridges are over 305 M in length. The girders of all these bridges are of rivetted design though there are quite a few bridges viz.
