Embodiment Construction
[0021] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0022] Such as figure 1 and figure 2 As shown, in the method for welding the outer cylinder and the bottom plate in the base of the middle and lower core shell of a high temperature gas-cooled reactor according to the present invention, the two inner cylinder tooling 1 and the outer cylinder tooling 2 are placed on the site, and the inner cylinder tooling 1 and the outer cylinder The tooling 2 is cylindrical, and the diameter of the outer tube tooling 2 is larger than that of the inner tube tooling 1, and then the base plate 3 is placed on the inner tube tooling 1 and the outer tube tooling 2, and the center of the base plate 3 is in line with the inner tube tooling 1 and the outer tube tooling 1. The center of the cylinder tooling 2 is concentric, and the outer cylinder 8 is placed on the bottom plate 3, and the welding parts of the two are...
