Patent abstract
An apparatus and method for remote frequency-based inspection of a valve seat includes inserting a frequency-based inspection tool into an inspection position over the valve seat and contacting the one or more supports to the inner surface of the valve seat. An input signal is transmitted at a desired frequency through the valve seat to a joint between the valve seat and a valve shaft via the one or more transducers. The shaft is rotated to remotely rotate the fixture, thereby allowing an inspection of an entire perimeter of the joint. An output signal is received and is evaluated to determine if an anomaly is present in the joint.
