    摘要： A welding apparatus and a welding method are employed for laser narrow groove welding which performs welding scanning a laser beam in the welding direction while feeding a solid filler metal into a narrow groove. The welding apparatus includes a laser beam irradiation head having a mechanism periodically oscillating an irradiation point of the laser beam with a predetermined amplitude in the bottom of the groove, and a filler metal control device having a solid filler metal feeder feeding the solid filler metal to the molten pool formed in the bottom of the groove by the laser beam and adjusting the feeding position independent of a motion of the laser beam irradiation head so that the tip position of the solid filler metal detected is constantly positioned in the center of the groove.

    摘要： 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. On the other hand, if the slots are left empty, a problem of degrading the fluid performance arises. To solve these problems, components are installed on the surfaces of the slots on the opposite side from the blades after the blades and the shroud in which the slots are formed are welded. 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.

    摘要翻译： 叶片连接到盘的表面，并且槽形成在护罩的表面中，护罩的表面与待焊接的刀片的护罩的另一个表面相对。 刀片设置在与槽相反的表面上，并且从其中形成槽的表面施加激光束以焊接护罩和刀片。 如果粉末熔化并放入形成为用于在护罩中焊接的槽以填充槽，则发生热变形。 另一方面，如果槽是空的，则出现降低流体性能的问题。 为了解决这些问题，在叶片和其中形成有狭槽的护罩焊接之后，将部件安装在与叶片相对侧上的槽的表面上。 或者，槽被填充有与护罩不同的材料，例如树脂。 利用这种结构，可以降低焊接热引起的变形，而不降低流体性能。 该方法可以应用于在叶片和盘被激光焊接之后叶片形成在护罩的表面上而不是在盘的表面上的情况下以及形成在盘中的槽。
