Abstract 900 t railway bridge girder erecting machine is a key equipment for construction of high -speed
railway and passenger dedicated line. At present, there is not special technological criterion or specification in
China for manufacturing and welding steel structure of railway bridge girder erecting machine. The reference
ideas are presented in this paper on welding technology for 900 t railway bridge girder erecting machine
through comparison and analysis of several state and trade technological critorions and standards.
