METHODS OF MANUFACTURING AXISYMMETRIC BODY AND AXISYMMETRIC PRODUCT

摘要

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.
