To further reduce the computational load in an inspection process of ultrasonic inspection of an inspection target. An ultrasonic inspection method includes the steps of: collecting data as a result of scanning an inspection target in such a manner that a plurality of probes transmit ultrasonic signals to the inspection target and the probes receive reflected ultrasonic signals from the inspection target; rendering a primary image including a contour and an internal side of the inspection target based on the data as the result of scanning by using a sonic speed of the ultrasonic signals transmitted and received by the probes, the sonic speed being set to a predetermined value regardless of a region through which the ultrasonic signals have passed; and evaluating whether an internal flaw is present in the inspection target in the primary image.

Multi-centric radius focusing is used to inspect a radiused surface of a radiused part having a varying radius without mechanically adjusting the array sensor. A plurality of focal laws are designed to electronically steer and focus ultrasound at respective focal points corresponding to centers of curvature of a simulated radiused surface having a varying radius. The mechanical probe that carries the array sensor is located to two physical places that are outside of the radiused area and have a spatial relationship that varies less than the radius of the radiused surface varies. As the probe is moved along the radiused part, the probe maintains the array sensor at a constant location relative to the radiused part. As the array sensor scans the radiused part, the array sensor is electronically adjusted to focus at the respective focal points in sequence.

A defect inspection device (100) includes an excitation unit that excites an elastic wave, an irradiation unit (2) that applies laser lights, a measurement unit (3) that measures the interfered laser lights, and a control unit that acquires vibration state information which is information about a state of the elastic wave excited in an inspection target (P) for a plurality of frequencies by changing a frequency of excitation vibration caused by the excitation unit in order to excite the elastic wave in the inspection target (P), and extracts recommended frequencies (F) recommended for inspecting a defect of the inspection target (P) from among the plurality of frequencies based on the acquired vibration state information for the plurality of frequencies.

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 system for non-destructively inspecting tubes is provided. The system may include a tank filled with a fluid, e.g., water. The tank may define an axial passage within it for tube insertion, and the tank may include an opening to the axial passage. A transducer probe may be disposed inside the tank and oriented toward the opening to the axial passage. The system may also include a movable seal including a chamber, configured to move axially in the axial passage, and a membrane positioned in the opening of the tank. During inspection, an acoustic pathway may be provided between the transducer probe and the tube, the pathway including fluid in the tank, the membrane, and fluid in the chamber.

An apparatus for guided wave testing of a test object comprises a linear array of receiver electromagnetic acoustic transducers (EMATs), and at least one linear array of transmitter EMATs disposed substantially parallel to the linear array of receiver EMATs and configured to launch guided waves in said test object in a direction substantially perpendicular to the at least one linear array of transmitter EMATs. Either (i) transmitter coils of the at least one linear array of transmitter EMATs have a common winding direction, receiver coils of adjacent receiver EMATs have alternating winding directions, and receiver coils of at least two adjacent receiver EMATs are connected in series, or (ii) transmitter coils of the transmitter EMATs have alternating winding directions, receiver coils of adjacent receiver EMATs have a common winding direction, and receiver coils of at least two adjacent receiver EMATs are connected in series.

To acquire information relating to degradation of a pipe on the basis of information that can be acquired using a simple method. The analysis device according to one embodiment is provided with: a determining unit for determining whether or not the accuracy of a pipe network model based on information that includes a parameter that changes in value in accordance with degradation of a pipe satisfies a predetermined criterion; and a derivation unit for deriving information relating to degradation of the pipe, based on the parameter, if the accuracy satisfies the predetermined criterion.

Apparatus and methods for ultrasonic inspection of elongated composite members in a single scan pass using pulse echo phased arrays operating in a bubbler method. The system concept is fully automated by integrating an inspection NDI probe assembly to a robot and using the robot to move the inspection NDI probe assembly along the part (i.e., outside of an inspection tank); and by integrating tooling fixtures that move out of the way as the inspection NDI probe assembly travels along the length of the part during the inspection. In addition, the system allows for generally elongated composite members having lengthwise variation in shape, curvature and dimensions.
