A labyrinth seal of the variety used with a rotatable shaft and a coaxial shroud spaced from the shaft is provided with replaceable tooth segments. In one form, the segments are disposed within a groove circumscribing the shaft, the groove having an overhanging shoulder, and the base portions of the tooth segments partially underlying the shoulder. A retaining metal deposit is applied to the base portions within the groove. Replacement of tooth segments is accomplished by removing the retaining metal deposit, removing worn tooth segments and replacing them with new tooth segments.
