Abstract:
An inspection scanner is described that has a low profile construction designed to fit into tight spaces and inspect structures such as weld joints. Wheel frame assemblies carry a probe holder assembly with an ultrasonic (US) array that emits US beams through the structure and receives reflected sound waves. The probe holder assembly extends and US beam is angled away to inspect in tight locations. The wheel frame assemblies roll on wheels that drive an encoder. Encoder 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. The wheels may be magnetic to hold it to the structure being inspected. A brake system may be employed to hold the inspection scanner at a given location.
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.

Abstract:
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.
