摘要： The present invention relates to a method of joining a hub 11 and a shroud 12 of an impeller 10, either one of which has blades 13 integrally formed thereon, by welding. During the welding, in an upright state in which the hub 11 is placed to face a mount surface, the hub 11 and the shroud 12 are placed on top of each other to form an assembled body 10. Welding is performed on the assembled body 10 covered with a heat insulating jacket 30(a to g), the jacket 30 covering the assembled body 10 except an open region (OP) and an inflow port 14IN required for welding. When welding of one open region OP is completed, a new open region OP is formed by moving the heat insulating jacket 30 with respect to the assembled body, and then the next welding is performed.
