Patent number: 8813567Abstract: An inspection scanner [1000] is described that has a low profile construction designed to fit into tight spaces and inspect structures [10] such as weld joints [13]. Wheel frame assemblies [1100, 1200] carry a probe holder assembly [1110] with an ultrasonic (US) array [1400] that emits US beams through the structure [10] and receives reflected sound waves. The probe holder assembly [1110] extends and US beam is angled away to inspect in tight locations. The wheel frame assemblies [1100, 1200] roll on wheels [1140, 1240] that drive an encoder [1250]. Encoder [1250] provides the specific locations for the received sound waves with respect to the weld. The locations and received sound waves are used to reconstruct a signal showing imperfections inside of structure [10]. The wheels [1140, 1240] may be magnetic to hold it to the structure [10] being inspected. A brake system [1600] may be employed to hold the inspection scanner [1000] at a given location.Type: GrantFiled: December 10, 2012Date of Patent: August 26, 2014Assignee: ALSTOM Technology LtdInventor: Jacques L.

Patent number: 7984650Abstract: 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.Type: GrantFiled: June 24, 2008Date of Patent: July 26, 2011Assignee: Alstom Technology LtdInventor: Jacques L.
