Abstract
A scanner device for performing nondestructive testing of a tube includes an ultrasonic probe, a waveguide (wedge) secured relative to the probe, and an encoder secured relative to the probe. The waveguide has a surface contoured in relation to a radius of a tube to be inspected, and the encoder provides a signal indicative of a location of the probe relative to the tube as the probe, waveguide, and encoder are moved in a direction of a longitudinal axis of the tube. In one example, the tube is part of a waterwall, and the surface of the waveguide extends substantially from a web on one side of the tube to a web on the opposite side of the tube. The waveguide may be removably secured relative to the probe such that the waveguide can be replaced with a waveguide having a different surface contour in relation to a different radius of a different tube to be inspected.
