Abstract
PURPOSE: To make not to be beside the point of electron beam, by welding the members having a fixed shape and material on both ends of nozzle fin and then, welding the above member with inner and outer rings through the partition plate having the same material to the above rings.
CONSTITUTION: The members 5, 5 having the same material to the inner and outer rings 3, 4 and the same sectional shape to the nozzle fin 1, are fixed on both ends of the fin 1 by TIG arc welding and mechanical processing is carried out on the surface of the first weld zone 6. Next, the above members 5, 5 are inserted in the perforations 2a, 2a having the same sectional shape to the above fin 1 provided boring on the partition plates 2, 2 composed of the same material to the rings 3, 4. The above members 5, 5 and the circumference edge of opening face of the perforations 2a, 2a, are welded and mechanical processing is carried out on the surface of the second weld noze 7. Then, the plates 2, 2 and the rings 3, 4, are welded and electron beam welding of faying face is carried out
