Abstract

The invention discloses a welding method for assembling the parts of a fusion reactor test blanket module and aims at solving the assembling and manufacturing problems for the parts of the test blanket module. The invention is characterized in that the welding steps comprise in sequence: a, a radical pole clapboard is welded on a first wall; b, an annular pole clapboard is welded in an area formed by the radical pole clapboard and the first wall; c, an upper cover plate and a lower cover plate are welded on the first wall; d, back plates and pipe branches are welded in sequence from the inside to the outside; e, finally, a dividing / receiving box is welded on the back plate at the outermost layer. The welding method has the advantages of simple technique, small welding deformation, programming manufacture process, and the like. The welding method is suitable for manufacturing the test blanket modules with various structural forms.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding method for assembling fusion reactor experimental cladding module components. Background technique [0002] The main function of the cladding of the fusion reactor is to convert the kinetic energy of the fusion product particles into heat energy while multiplying tritium to maintain the core fusion reaction. The experimental cladding module is the preview carrier of fusion reactor cladding related technologies. A schematic diagram of the structure of an experimental cladding module such as figure 1 As shown, its main components include the first wall, ring pole separator, radial pole separator, back plate, upper and lower cover plates, branch pipes, and distribution / receiving boxes, etc., and its structural materials generally use low-activated iron. Nutritic / martensitic steel. Depend on figure 1 It can be seen that the experimental cladding module composed of thes...
