Abstract: For a period of time, in the construction of large cable-stayed bridge in China, the cable force anchorage system of the cable at the beam mainly has two forms of anchor box type and pull plate type, both of which have their own advantages. The Daxi River Bridge adopts the external steel anchor pipe anchorage system, which is evolved on the basis of anchor box type and pull plate type (built-in anchor pipe). Based on the advantages of both, the structure is simple theoretically and has clear force transmission, which is a major innovation of cable anchorage structure. The anchorage structure of external steel anchor pipe is that the cable force is first transmitted to the steel anchor pipe through the pressure plate, then to the anchor web, and finally to the main beam web. The cable force is transmitted in the form of shear force. The anchoring web is an important force transfer member, which is connected by the steel anchor pipe, the web, the top plate and the Lower plate of the main beam, the welding is full penetration, the plate is thicker and the force is complex and changeable. Therefore, the welding production of cable beam anchorage structure of Daxi River bridge is the key to the successful manufacture of the steel structure. In this paper, the welding process is summarized from the welding method, welding equipment, welding material, groove form, welding preheating, welding order, 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.
