JOINTING METHOD OF MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for repairing parts such as a rotary disc/ drumrotor of a gas turbine engine. SOLUTION: This method includes steps for: heating a contact area 207 of a forged material and a contact area 307 of forged parts; pressurizing the contact area 207 of the material to the contact area 307 of the parts to joint them. A method for producing rotary parts of the gas turbine engine includes a step for heading the contact area 207 of the forged material and the contact area 307 of the forged parts, and a step for pressurizing the contact area 207 of the material to the contact area 307 of the parts to joint them. This method may include a sequential heat treatment step for giving a desired strength characteristic to a joint part 309 between the material and the parts. COPYRIGHT: (C)2003,JPO
