| Summary: | The development of power grid is showing that voltage level is from low to high, networking scale is from small to large, level of automation is from weak to strong.. [1] as the hub of power grid connection between substations, the capacity and automation level of substations is also improving. The large diameter and thick walled tubular busbars of substations have been widely applied. Because of the wide application of tubular aluminum busbar, its welding quality has affected the overall quality of the power plant. Therefore, it is an effective way to improve welding level of power station busbar by scientifically making technological measures and welding codes and carrying out adaptive training for welding operators. In view of the feasibility of the argon arc welding (MIG) welding process and the feasibility of training for the tubular aluminum busbar of UHV power station, the characteristics of the welding technology of tubular aluminum busbar and the technological measures taken by the welding technicians are discussed.
