This study is to investigate the welding characteristics of Zr-4 end plate of fuel bundle in the cases of RW and LBW. The welding parameters which affect the weld nugget and the torque values have been also compared. The effect of the torque strength of end plate welding using by RW and LBW has been studied and optimum conditions of Zr-4 end plate welding have been found. Futhermore, microstructures and micro-hardness of resistance welded specimens have been also compared.
