An ultrasonic matrix phased array inspection system can include a plurality of curved matrix phased array probes surrounding a test chamber through which a longitudinal test object passes. Fluid injectors can provide a rotating fluid jacket around the longitudinal test object to ultrasonically couple the plurality of curved matrix phased array probes to the longitudinal test object. The plurality of curved matrix phased array probes can remain in a fixed position during inspection and can inspect the longitudinal test object by transmitting ultrasonic sound waves at various angles to identify flaws of any orientation.

A data capture device and a data capture system are provided. The data capture device is configured to navigate along an elongate structure. The data capture device includes a surface scanner, for scanning a surface of the elongate structure; and a sensor, for capturing data relating to the elongate structure. The surface scanner and the sensor are configured to capture data relating to a common region.

An inspection device inspects a joint-type outer joint member of a constant velocity universal joint that includes a cup section having a bottomed cylindrical shape and track grooves in an inner periphery thereof for torque transmitting elements, and a shaft section extending from a bottom of the cup section. The inspection device inspects the outer joint member, which is obtained through melt-welding on a cup member forming the cup section and a shaft member forming the shaft section. The inspection device includes a surface inspection unit to inspect for a defect which appears on a surface of the outer joint member due to welding, an internal inspection unit to inspect for an internal defect of a welded portion, and a recording unit to record an inspection result of the inspection. The inspection device is configured to efficiently perform in-line total inspection for the melt-welded joint-type outer joint member.

A threaded connection make up monitoring system includes an acoustic emission transducer operatively connected to one positioned to capture an acoustic signature associated with forming the threaded connection between a first member and a second member. A controller is operatively coupled to the acoustic emission transducer. The controller is operable to receive a signal from the acoustic emission transducer embodying the acoustic signature. The controller is operable to output a signal indicating whether the acoustic signature represents a properly made up threaded connection of the first member and the second member or whether the acoustic signature represents an improperly made up threaded connection of the first member and the second member.

An ultrasonic test device and test method for service stress of a moving mechanical component, where the device comprises an ultrasonic probe, a coupling fluid, a pressure-maintaining cover and universal wheels. The cover is vertically arranged above an inspected position of an inspected component, an interior of the pressure-maintaining cover is filled with coupling fluid, a bottom of the cover is provided with a structure permeable to the coupling fluid to form a coupling fluid film between the inspected position and the bottom of the cover, and a top of the cover is equipped with the ultrasonic probe. A detection part at a lower part of the ultrasonic probe extends into the coupling fluid of the cover and is vertical to the bottom of the cover without contact. The distance between the ultrasonic probe and the inspected component is kept unchanged through the universal wheels.

Disclosed is an ultrasonic bar or tube inspection assembly comprising two centering assemblies and two inspection cassettes. The centering assemblies are designed to guide the bar under inspection with rollers disposed on symmetrically arranged pivot arms activated by a single centering ring. A pressure plate is designed to push the probe cassettes to be stacked tightly and concentrically onto the centering assembly. The inspection probe cassettes, with the accompanying design of engagement grooves and ridges, and a pressure plate, may be easily removed from the bar inspection assembly for maintenance operations.

A system and method passively normalize an ultrasonic dry coupled wheel probe as the probe traverses a surface of a structure to inspect the structure, such as a flat structure or a curved pipe. At least a pair of arms are configured to passively maintain normalization of the probe in a detection direction normal to the surface.

A system for non-destructive testing of a bond condition of concrete beams reinforced by steel rods is described. The system includes a transducing transmitter, a transducing receiver, and an ultrasonic pulse generator configured to generate drive signals for the transducing transmitter and receive a plurality vibrational waves at the transducing receiver. The system further includes a computing device including a measurement circuit configured to record a transit time for each vibrational wave and divide a distance between the transducing transmitter and the transducing receiver by the transit time to determine a pulse velocity of each vibrational wave, a comparison circuit configured to identify a highest pulse velocity of the vibrational waves and compare each highest pulse velocity to a first reference pulse velocity, and a decision circuit including an artificial neural network configured to identify a compromised bond condition around a steel rod.

A portable inspecting device includes PZT transducers and performs active sensing to measure the characteristics of bolted connections. The PZT transducers are mounted on opposing ends of spring-loaded rods and can be moved apart to accommodate a structure for testing. The springs cause the PZT transducers to push against opposing parts of the structure in a stable but temporary fashion. The device can be physically moved to inspect the status and health of multiple different bolted connections.
