PURPOSE:To facilitate the automation of welding of a rotor spider shaft by a method wherein a tangent directional slot is provided at the edge face of a rib, a beveling is provided at the lower edge part, while a non-welded part is provided at the edge part of the rib. CONSTITUTION:A tangent directional slot 2e is provided at the edge face of a rib 2. Welding 2b is not performed up to the edge part, a partially non-welded part is made as to be left, and moreover welding at the edge face is omitted. Moreover, a beveling B is provided at the edge part of the rib 2. Accordingly automation of welding of the rotor spider shaft is facilitated extremely. |
