Abstract: In the repair or replacement of vane assembly retaining lugs, a replacement lug of a wrought alloy is solid state bonded to the vane assembly in place of the previous retaining lug. The existing lug is first removed from the assembly to leave a stub portion which is machined to form a surface to which a replacement lug may be bonded. A replacement lug blank is then positioned adjacent the stub face, a vacuum drawn in that region and a bonding force applied, the interface between the stub and replacement blank being heated locally. After bonding the assembly is heat treated and the replacement lug machined to a desired configuration.
