Depressed portions are partially provided in a vibration surface of the base material toward a joining surface of the base material that is in a propagation direction of a sound wave.

The present invention discloses a visual ultrasonic nondestructive testing device and method for a deep/long-hole pipe. The device is composed of an ultrasonic measurement module, a mechanical motion module, a control module, and a coupling injection and assistance module. The ultrasonic measurement module includes an ultrasonic pulse transmitter/receiver, and the ultrasonic transmitter/receiver includes a high-speed analog/digital (A/D) converter; the mechanical motion module includes a scanning device, a probe and a holding device thereof, and a magnetic drive device. A scanning device can move in two directions, that is, an X-axis on which a magnetic driving wheel steps and a Y-axis on which a module body tests. During the scanning process, on the X-axis, a stepping motor drives a synchronous wheel-belt transmission, so that the magnetic driving wheel is rotated to achieve the purpose of stepping; on the Y-axis, a stepping motor on the module body drives the probe to reciprocate.

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.

A processing system according to an embodiment includes a processing device. The processing device receives a detection result of a reflected wave from a detector that includes multiple detection elements arranged in a first direction and a second direction crossing each other, and performs a probe that includes transmitting an ultrasonic wave toward a welding object and detecting the reflected wave. The processing device performs a first determination of determining a joint and a non-joint at multiple points along the first and second directions of the welding object based on the detection result. The processing device performs a second determination of determining an appropriateness of a result of the first determination by using a circularness of a first region based on the points determined to be joints.
