Abstract

PURPOSE:To produce at low cost the three dimensional curved face wing of cavitation resistance and errosion resistance by forming a wing part with rolling a plate material and by welding the wing part to a boss part. CONSTITUTION:The blank plate 10 for wing part which is cut in the prescribed wing width and length by a gas cutting, etc. is prepared. The plate 10 shall be of the material having high tensile strength, high sea water corrosion fatigue strength, high caviation resistance and high corrosion resistance. The wing face 13 of three dimentional curved face is then produced with rolling the surface of the wing part blank plate 10 by rolling a rolling roller 12 along the wing face gage plate 11 with pinching from both parts the blank plate 10 by the wing part gage plate 11. Then the boss part made in advance by casting or welding, etc. with using inexpensive ferrous materials and the wing part 14 where the wing face 13 is produced are welded, thereafter a residual stress is removed with locally annealing by applying a panel heater, etc. to the weld part 16. The machining on the wing part 14 is performed on its rear progressing face and outline only, then. With welding the wing part 14 to the boss part 15 in the prescribed numbers a complete product is made by performing an annealing and machining uniformly.
