20080237195 | WELDING SLOT SEALING STRUCTURE AND WELDING METHOD - Blades are connected to the surface of a disk and slots are formed in the surface of a shroud, which is opposite from the other surface of the shroud where the blades are to be welded. The blades are arranged on the opposite surface from the slots and a laser beam is applied from the surface in which the slots are formed, to weld the shroud and the blades. If powder is melted and put in the slots formed for welding in the shroud to fill the slots, thermal distortion occurs.

Alternatively, the slots are filled with a material different from that of the shroud, such as a resin. With this configuration, distortion caused by welding heat can be reduced without degrading the fluid performance. This method can be applied to the case where the blades are formed on the surface of the shroud, not on the surface of the disk, and to the slots formed in the disk after the blades and the disk are laser-welded. | 10-02-2008 |
