Embodiment Construction

[0031] A method for manufacturing an axisymmetric body according to an embodiment of the present invention is used for manufacturing figure 1 An axisymmetric body 1 having a shape symmetrical about a central axis 10 as shown. In this embodiment, the axisymmetric body 1 is formed in the axial direction ( figure 1 The middle is downward) the hollow of the upper opening. Specifically, the axisymmetric body 1 includes: a top wall 11, a tapered peripheral wall 12 extending from the peripheral portion of the top wall 11, and two first flange portions 14 protruding radially inward from the middle part of the peripheral wall 12 (equivalent to The flange portion in the present invention), and the second flange portion 13 protruding radially inward from the tip end of the peripheral wall 12 .

[0032] However, the shape of the axisymmetric body 1 is not limited to figure 1 the shape shown. For example, the peripheral wall 12 of the axisymmetric body 1 can also be straight. Moreover...

Abstract

An annular initial layer (31) comprising multiple beads (35, 36) is formed by laser metal deposition on the radially inwards- or outwards-facing peripheral surface of a base material (2), the width of the initial layer (31) being at least twice the width of the beads (35, 36), and multiple annular raised layers (32), each comprising multiple beads, are laminated on the initial layer by laser metal deposition. By this means, an axially symmetric body (5) having a relatively wide flange can be manufactured while the portion of the base material (2) that is affected by heat is kept extremely small.

Description

technical field [0001] The present invention relates to a method of manufacturing an axisymmetric body having a flange portion, and a method of manufacturing an axisymmetric product formed from the axisymmetric body obtained by the manufacturing method. Background technique [0002] The axisymmetric body having the flange can be produced, for example, by casting or cutting out a cylindrical or thick cylindrical material. However, in casting, the fabrication of metal molds requires a large expense. Also, a lot of material is wasted during chipping. Contents of the invention [0003] Problems to be solved by the invention: [0004] Therefore, it is desirable to form the flange portion after the base material. For example, a ring-shaped sheet material may be joined to a tubular base material by full penetration welding. However, since the heat input to the base metal during welding is very large, the heat-affected zone (HAZ) in the base metal is relatively large. [0005...
