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.
