Li Yan · Electric Welding Machine · 2010
There is a severe deformation in the welding of core barrel in Qinshan Nuclear Power Phase II Extension Project Reactor 3# unit.After welding,the dimension of core barrel is quite out of the tolerance to the design requirement.To assure the normal function of the core barrel,measures must be adopt.Firstly,the paper introduces welding deformation in Qinshan Nuclear Power Phase Ⅱ Extension Project Reactor 3# unit.Then combining the design requirements,the paper brings forward specific disposal measurements.The disposal result is successful.
