AI Technical Summary

Technical Problem

The positioning edge of the support ring of the fan-shaped component of the aero-engine is prone to defects such as deformation, burning and hot cracking under high temperature environment, which leads to reduced weldability and makes it difficult to repair with high quality.

Method used

Through steps such as measurement, machining, pre-weld heat treatment, manual welding and shaping, automatic rail welding, post-weld heat treatment and cold straightening, the size and shape of the support ring positioning edge are restored, deformation is eliminated, and weldability and repair quality are improved.

Benefits of technology

This method achieves high-quality repair of the support ring positioning edge, eliminates deformation, improves weldability and repair effect, and avoids the high cost of purchasing new parts.
