A turbine blade assembly for a turbine assembly includes a turbine blade having a turbine blade damper cavity formed therein and a plurality of pins positioned within the turbine blade damper cavity. A channel isolation structure decreases leakage current through a channel structure. The temperature detector controls the toggling unit for increasing the absolute value of the monitoring level with an increase in temperature with high temperature sensitivity. Therefore, the system and method enables welds of a quality less than a pre-determined quality for the weld to be identified in real-time and information concerning any particular weld to be accessed at a later time. The method still further comprises assigning a visual indicator to the location data point based on the EP parameter value associated with the identified point and in accordance with a visualization scheme corresponding to the EP parameter.
