摘要： Non-limiting examples of the present disclosure relate to devices, systems and methods of manufacture for an exemplary waveguide usable for acoustic signal transmission for non-destructive evaluation (NDE) of a wooden specimen. An exemplary waveguide comprises a mating portion for interfacing with a transducer horn of an ultrasonic transducer. The mating portion comprises an impact surface and a contact well that is fabricated within the impact surface so that the contact well is not contacted during an impact that drives the waveguide into wood. The contact well is utilized to connect the waveguide to a transducer horn. The waveguide further comprises a body portion that comprises a radiating component optimized for non-destructive evaluation (NDE) of wood and transmission of ultrasonic signal data. Further non-limiting examples describe an interfacing component for securing one or more devices to the waveguide as well as an extraction component that is configured to minimize damage to the waveguide during extraction.

摘要： An aspect provides an ultrasound device for non-destructive evaluation of a butt-fusion joint or electro-fusion joint, the device comprising: an ultrasonic unit; a transducer operable remotely from the ultrasonic unit and including an ultrasound signal transmitter positionable to transmit the signal towards the joint, and an ultrasound signal receiver positionable to detect a reflection of the signal; a processor; memory including instructions executable by the processor and first data relating to a plurality of first sample joints of acceptable quality and second data relating to a plurality of second sample joints of unacceptable quality; and an output device. The instructions include a machine learning algorithm trained for analysis of the joint and to send assessment output to the output device indicative of whether the joint is of acceptable or unacceptable quality based on the signal reflection and the first and second data.

摘要： Provided is an ultrasonic probe having ultrasonic elements and a printed-circuit board that establishes connection between the ultrasonic elements and external wiring, achieving strong connection between the ultrasonic elements and the printed-circuit board mechanically and electrically, and thereby improving performance in examination and diagnosis using the ultrasonic probe. The printed-circuit board with pads each having a via-hole to be bonded to electrode pads of a chip equipped with the ultrasonic elements, is provided with a reinforcement, in an area of the base material where the pad having the via-hole is not formed. The reinforcement is formed simultaneously with forming the pads and wiring on the printed-circuit board, having the same thickness as the pads. With the reinforcement, pressure is evenly applied to the printed-circuit board when the electrode pad is press-fitted into the pad having the via-hole, thereby preventing warping and deforming of the board.

摘要： A robot system for non-destructive testing (NDT) of a test object, including: a transducer holder and an NDT transducer to perform an NDT on the surface of the test object; a memory to store a predefined trajectory of the NDT transducer; a force-sensing device to provide measurements of the contact forces and/or contact moments between the surface of the test object and the NDT transducer and/or the transducer holder; a controller to generate an actuation signal based on the predefined trajectory; and a positioning device to control the position and/or orientation of the NDT transducer relative to the test object based on the actuation signal. Consequently, the position and/or orientation of the NDT transducer relative to the test object and the contact forces and/or contact moments between the NDT transducer and/or the transducer holder and the test object can be automatically adapted to improve the quality of the NDT measurement.

摘要： A material profile can be determined by assuming an elliptical or circular arc geometry and by using acoustic noise generated by diffuse internal reflection and/or specular reflection on the internal (ID) or external (OD) interface of the material under inspection, such as a pipe or curved plate. A non-destructive testing (NDT) technique can acquire acoustic data of the material using an ultrasonic signal. The acquired acoustic data can be filtered such that the acoustic noise generated by diffuse internal reflection and/or specular reflection is separated from any flaws in the material. Positions of the acoustic noise can be determined and then a regression technique can be applied to the positions, which can generate an equation of a circle, for example, such as to provide a radius and thickness of the pipe or curved plate.
