1. Processing preparation and blanking of steel structure canopy: setting out shall be carried out according to the construction drawing. During setting out and marking off, the welding shrinkage and machining allowance shall be reserved, and the template shall be made according to the setting out. Steel correction: it is necessary to correct the steel before blanking. The error value after correction should not exceed the allowable error value of the specification rules to ensure the blanking quality. The hot processed section steel shall be hot processed first, and the hole shall be numbered after cooling. Steel plate embedded parts and other parts shall be cut, drilled and sprayed with anti-corrosion paint.

4. Welding of suspension arm device: the length of suspension arm of the project exceeds 7.2m, the device is welded, and the steel corner code is strengthened and fixed. Before the installation, the suspension arm shall be adjusted to plan the slope, and the welding can be carried out only after it is accurate. After one suspension arm on the side is accurate, another suspension arm on the other side of the device shall be spot welded after it is in place. Then take the two suspension arms as the benchmark, pull out the highest and lowest elevation lines of the suspension arms, weld the remaining suspension arms one by one, and weld the seamless steel pipe pull rod. Straighten the joint and weld the joint first. When selecting section steel joints, in order to make the joint section steel close to the embedded parts of steel plate, the edges and corners shall be removed according to the planning requirements. For butt welds, arc striking plates shall be welded on both ends of the weld, and their raw materials and wave mouth types are the same as those of the weldment. Calibration and inspection: after the suspension arm device, first check the quality of the on-site connection parts. For the quality of suspension arm device, first check the non straightness of the vertical surface of the suspension arm; The side surface of the vertical surface of the compression arm sags; Boom slope. Ensure that the suspension arm meets the planned stress condition and all safety and stability requirements.
