Abstract
Method is for assembling a disk fitted with small wings. The small wings are composed of a foot made of an element with the disk and welded blades. The disk and the blades are installed on a rotating template with fixing means in the desired position and elements are merged at the joining surface by an electron gun or similar device. The small wings are successively welded during one or two operations. Screens for halting heating radiation are situated behind the wings to be welded. Rotors of turbines and compressors may be assembled in this manner.
