Research on welding technology of cable anchorage structure of Daxi River Bridge

Daxi River Bridge adopts steel-concrete composite beam cable-stayed bridge, whose external steel anchor pipe anchorage system is an important design innovation of the whole steel bridge structure. The anchoring web is an important force transfer member, which is connected around by the welding of full penetration. Therefore, the welding production of cable beam anchorage structure of Daxi River bridge is the key to the successful manufacture of the steel bridge structure. The welding process is summarized from the welding method, the welding consumables,groove form of the joint, welding preheating, welding sequence, specification parameters, nondestructive testing requirements, welding number requirements, so as to provide reference for the optimization of cable beam anchorage structure welding process and the intelligent improvement of welding equipment in the future.
