Offshore wind farms in Europe and America are on the verge of large-scale development. my country's eastern coastal areas have vast waters within 50 meters of depth, and are close to power load centers (economically developed coastal areas with power shortages). With the development and maturation of offshore wind farm technology, wind power will undoubtedly become an important energy source for the sustainable development of my country's eastern coastal regions.

Due to the large volume of the monopiles, the existing welding fixtures are complex in structure, inconvenient to operate, and cannot guarantee the welding quality of the monopiles. Therefore, a welding fixture for assembling offshore wind turbine monopiles was designed. Utility Model Content
