Abstract

The invention discloses a local heat treatment device and method for a repaired aviation titanium alloy large-scale complex structural member, and the device comprises a heater which is used for heating the repaired part of the aviation titanium alloy large-scale complex structural member in an attached manner; the temperature sensor is used for detecting the temperature of the repaired part of the aviation titanium alloy large complex structural part; and the temperature controller is respectively in communication connection with the heater and the temperature sensor. By means of the scheme, local heat treatment can be effectively conducted on the repaired part of the large complex aviation titanium alloy structural part, the size of the heat treatment device can be greatly reduced, and out-of-tolerance caused by thermal deformation of the repaired workpiece can be prevented.

Description

technical field [0001] The invention relates to the technical field of local heat treatment after repair of a large complex structure of aviation titanium alloy, in particular to a device and method of local heat treatment after repair of a large complex structure of aviation titanium alloy. Background technique [0002] The working environment of large and complex aviation titanium alloy structural parts such as casing and integral blisk is a high temperature and high pressure environment. During the service process, damage and failure such as cracks, corrosion and wear are inevitable. The use of high-energy beam repair processes such as laser additive repair and electron beam welding to achieve rapid repair of damaged parts has significant economic benefits for extending the life of damaged parts. The high-energy beam repair process has the characteristics of rapid melting, which makes the structure of the repaired parts metastable, and the repaired structural parts inevit...
