A method for quantitatively evaluating the expected ultrasonic inspectability of a designed part using ray tracing. First, a model of a part imported. Materials having different indices of refraction are selected for the part and an acoustic coupling medium. Then the following structures and positional relationships are defined: an ultrasonic transducer array comprising a plurality of elements, a position of the acoustic coupling medium between the transducer array and the part, and a plurality of positions of a transmit aperture relative to the part. For each defined position of the transmit aperture, a path of a respective ray is traced from a center of the transmit aperture through the part and then to a respective receive location on the transducer array. Also, a respective value of an inspectability margin is calculated based at least in part on a respective distance between a center of the receive aperture and the respective receive location. Each value of the inspectability margin is compared to a threshold value.

A method and arrangement for testing and/or correction of a weld (34, 36, 38) of a test object (26, 102), including alignment of an ultrasonic probe (16, 128) guided by a robot (100) on a target position of the weld (28, 30, 32), determination of the actual position (34, 36, 38) of the weld by means of an optical sensor (22, 130) and alignment of the ultrasonic probe (16) on the actual position, and measurement of the weld, where CAD data of the target position of the weld (28, 30, 32) is made available, on the basis of the CAD data of the weld the ultrasonic probe (16, 128) is aligned on the target position of the weld, and the ultrasonic probe is placed on the weld with controlled force after determination of the actual position (34, 36, 38) of the weld by means of the optical sensor (22, 130).

A system and methods of nondestructive testing are described. The system includes an immersion ultrasonic probe and a laser vibrometer. The immersion ultrasonic probe and a sample are immersed in a fluid contained in an immersion tank and the laser vibrometer is disposed outside of the immersion tank. A tightly focused ultrasonic beam from the immersion ultrasonic probe and a laser beam from the laser vibrometer are both transmitted upon a sample, the laser beam being transmitted through the wall of the immersion tank. Since the ultrasonic beam is tightly focused and the laser beam samples only a small area impinged by the ultrasonic beam, microscopic resolution is obtained.

The present disclosure provides a system and method for real-time visualization of a material during ultrasonic non-destructive testing. The system includes a graphical user interface (GUI) capable of showing a three-dimensional (3-D) image of a composite laminate constructed of a series of two-dimensional (2-D) cross sections. The GUI is capable of displaying the 3-D image as each additional 2-D cross section is scanned by an ultrasonic testing apparatus in real time or near real time, including probable defect regions that contain a flaw such as a hole, crack, wrinkle, or foreign object within the composite. Furthermore, in one embodiment, the system includes an artificial intelligence capable of highlighting defect areas within the 3-D image in real time or near real time and providing data regarding each defect area, such as the depth, size, and/or type of each defect.
