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.

A method for reconstructing geometry of an object surface via echographic probing, using an ultrasound probe including plural transducers, the method including: controlling the transducers to transmit towards the surface ultrasound waves having initial transmission delays between them; executing at least once a cycle of operations including receiving from the transducers intermediate measurement signals, correcting transmission delays of the transducers using intermediate measurement signals, and controlling the transducers to transmit towards the surface ultrasound waves having the corrected transmission delays; receiving from the transducers final measurement signals resulting from reflection of a wavefront received simultaneously on the surface; determining specular travel times between each transducer and the surface based on the final measurement signals and the corrected transmission delays; and perform geometric reconstitution of the surface based on the determined specular travel times.

An automated system for non-destructively evaluating spot welds that includes at least one matrix phased array probe; a fixture adapted to be mounted on a robot or other mechanical actuator, wherein the fixture is further adapted to retain the at least one matrix phased array probe; and an enclosure that includes at least one input for connecting to the at least one matrix phased array probe, ultrasonic phased array transmitting and receiving circuitry in electrical communication with the at least one input, at least one data processor running software that includes at least one algorithm for processing data received from the probe and generating discrete specifications of evaluated welds, wherein the discrete specifications further include pass indications or fail indications regarding weld acceptability; and at least one output for outputting the discrete specifications of evaluated welds.

A system for identifying variations at a weld location and accommodating for the variations. The system includes two sensors positioned on each side of a welding location, with a welding device at the welding location. The sensors each emit a signal toward the welding location and receive feedback from the signal that indicates the shape and size of the welding surfaces at the welding location. The sensor information, along with the exact locations and orientations of the sensors, is utilized to determine whether one or more welding parameters should be adjusted.
