[0002] The wind turbine tower is the tower pole of wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the set. The production process of the wind turbine tower generally starts with the CNC cutting machine cutting, the thick plate needs to be beveled, and the plate rolling machine is rolled into shape, spot welding, positioning, and confirmation before welding the inner and outer longitudinal seams. After the roundness inspection, if there is a problem, a secondary rounding is performed. After the single-section cylinder is welded, the hydraulic group is used to assemble the roller frame for spot welding, the inner and outer circumferential seams are welded, and the straightness and other tolerances are checked. After the flange is welded, non-destructive testing and flatness inspection of the weld are performed, sandblasting, painting, internal parts installation and finished product inspection are completed, and then it is transported to the installation site. With the development of society, the application of corrosion-resistant wind turbine towers is becoming more and more extensive.
