<p>PURPOSE:To facilitate the welding works for speed ring which forms a narrow flow passage by forming a projection on one end surface of a stay vane and freely inserting said projection into the receiving hole on an annular main plate and treating with welding from outside the main plate. CONSTITUTION:A stay vane 4 is arranged at a fixed position on an annular main plate 3 on the underside, and fillet welding is applied on all circumferential edges. Then, on the stay vane 4, an annular main plate 2 on the upside is put, and the projection 7 of the stay vane 4 is inserted into the receiving hole 6 on the main plate 2, and welding is applied along welding line 8 from outside the main plate 2. Thus, as welding is performed from outside the main plate 2, works can be carried out easily.</p> |
