Research on Welding and Quality Control of Rotor Support of Baihetan Right Bank Power Station

The generator rotor is one of the main parts of hydro generator set, it has the characteristics of large size,many processes and complex structure. This paper takes the Right Bank Hydropower Station of Baihetan as an example, the welding quality control method of disc support rotor is introduced, the improvement measures of welding process for this kind of rotor bracket are summarized, the deformation control method and defect treatment measures in the welding process are mainly analyzed, in order to further improve the welding quality of rotor bracket.
