This makes manual welding of the internal longitudinal seams of offshore wind turbine towers difficult, and the dim lighting inside the towers further reduces work efficiency. Therefore, it is essential to develop an automated welding device for offshore wind turbine towers for use in the existing wind turbine tower production and processing field. Utility Model Content
