Repair or replacement of a projection such as a labyrinth seal tooth of a metal having relatively poor weldability characteristics is accomplished by removing a portion or possibly all of the seal tooth down to a pedestal and then metallurgically bonding as by fusing to the pedestal a second metal characterized as having good weldability characteristics when diluted with the first metal, and age hardenable with an aging heat treatment with which the first metal also is age hardenable.
