Abstract
Method of attaching a target for use in a system for monitoring the vibration of a plurality of shrouded turbine blades to a shroud segment.

The target is spot welded to the shroud segment of the turbine blades at the turbine site using portable welding equipment, providing effective and low cost installation.
