FCAW vertical welding of V butt plate in AC UHV transmission line construction
In twenty-first Century,China vigorously promoted the research and construction of AC and DC transmission technology in order to ensure the optimal allocation of energy resources in a large scale1.In the construction of AC UHV transmission line,the welding quality of tower and stiffening plate as the load bearing tower and the tension of the welded structure plays an important role in the overall quality of the steel structure.In the past,the welding process of semi automatic carbon dioxide solid core welding wire often has the characteristics of weld spatter not easy to clean up and low efficiency of welding.The semi-automatic CO2 flux cored arc welding,has the characteristics of current and voltage to adapt to a wide range,melting speed,has important significance for improving the process,this paper describes the technology in practical engineering applications,and developed the basic strategy of training for grid steel structure welding technicians.This paper also lists both V groove plate butt FCAW welding typical welding project,hope this welding process will continue to spread.
