SEPARATING GAS TURBINE ENGINE AIRFOIL TO PLATFORM BRAZED CONNECTION BY HEATING AND PULLING APART

摘要

A process and apparatus are provided for separating components of a brazed vane assembly by preheating the assembly to a temperature below the solidus of the base metal of the vane assembly and above the liquidus of the braze, then maintaining such temperature while separating the airfoil from the platform by pulling/pushing the airfoil and platform apart.
