Abstract:

Disclosed herein is a scanning device for performing ultrasonic nondestructive testing of a tube, comprising a housing; the housing having bottom surface that is concavely curved with cavities to accommodate a waveguide assembly and an encoder assembly; where the waveguide assembly comprises a waveguide and a probe that are in communication with one another; the waveguide having at least one surface that is contoured to match an outer surface of the tube; where the waveguide facilitates the transmission of ultrasonic signals into the tube generated by the probe; and where the encoder assembly comprises a spring loaded wheel that contacts the tube; and where the encoder assembly provides a signal indicative of a location of the probe relative to a position on the tube as the scanning device is moved in a direction of a longitudinal axis of the tube.
