PURPOSE: A storage turning device of a laser welding machine for welding a nuclear fuel storage of a light-water reactor is provided to perform a welding process without stopping by simply rotating a storage. CONSTITUTION: A storage turning device of a laser welding machine for welding a nuclear fuel storage of a light-water reactor comprises a storage(1), a clamp(20), an extension shaft(23), a handle(45), and pneumatic cylinder. The facing surfaces of the storage split into halves are temporarily welded to be formed in a rectangular shape. A circular drum is attached on the free end of the clamp. The clamp is interlocked with a shaft(21) so that a pressing plate can be adhered to the inner wall of the storage. The extension shaft is rotatably supported by a housing(20a). The handle is rotatably assembled in the housing. The pneumatic cylinder is ascended and descended and rotatably supports the circular drum. |
