A system and method directed to inspecting a high density polyethylene pipe. The system includes a pipe inspection tool that is positioned about a fused polyethylene pipe joint. The inspection tool may include search units, a pipe carriage, a pulser and a phased array testing instrument programmed to adjust an amplitude response signal from the search units based on a vertically established time corrected gain curve. The inspection tool is rotated around the high density polyethylene pipe joint while propagating acoustical waves at various patterns and angles through the polyethylene pipe joint. Prior to the joint inspection, the inspection tool is calibrated using a calibration tool which includes a block having an array of equal sized bores positioned along different axis' through the block's depth. The block is constructed of the same material type and grade as the pipes that were fused together to form-the polyethylene pipe joint.

A system for ultrasonic examination of spot welds comprising a probe, a computer, and a display screen, the computer configured for spot weld analysis by appropriate analytical software, the probe for coupling to a spot weld via a couplant, wherein the probe comprises a two dimensional array of sensors that is each configured to conduct an A scan analysis, thereby providing a color pixel indicating weld quality in terms of parameters selected from the group of size, shape, voids, upper sheet-weld nugget interface strength and lower sheet-weld nugget interface strength, such that the two dimensional array of sensors produces a two dimensional pixilated image indicating the weld quality in terms of selected parameters.

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 an air pocket, delamination, or foreign object within the composite. Furthermore, in one embodiment, the system includes an artificial intelligence capable of highlighting foreign objects within the 3-D image in real time or near real time and providing data regarding each object area, such as the depth, size, and/or type of each defect.

A method and a device for testing a component by means of ultrasound is described. It is based on using transducers (4) for sending a probe signal into the component and monitoring its propagation. The response signals (C1 . . . C7) of the individual receivers are analyzed for the strength (A) of the arriving surface wave, and this strength (A) is used for scaling the response signals (C1 . . . C7). This allows to compensate for variations in the coupling strength between the various ultrasonic transducers {4}.

A method and device for processing an echo signal received from an acoustic sensor. The echo signal is detected over a measurement time interval. A minimum value is ascertained, which describes a minimum amplitude of the echo signal within the measurement interval. An amplitude value is ascertained, which describes an amplitude of the echo signal within a measurement window. The measurement window is a predefined time interval within the measurement interval. A difference is ascertained between the minimum value and the amplitude value. A determination is made whether the echo signal comprises an interference signal of the first type or an interference signal of the second type, based on the ascertained difference.

A machine tool includes: a first calculator configured to calculate a first frequency characteristic based on a first oscillation signal and a measurement signal of a physical quantity measured by a measurement unit when the drive shaft of a servo motor swings in accordance with the first oscillation signal; and a second calculator configured to calculate a second frequency characteristic based on a second oscillation signal and a measurement signal of the physical quantity measured by the measurement unit when the drive shaft of the servo motor swings in accordance with the second oscillation signal.

A pressure testing method capable of determining with a higher accuracy whether a high-pressure tank is deteriorated. The pressure testing method tests the high-pressure tank that includes a liner and a fiber-reinforced resin layer covering the outer surface of the liner and that has been used while repeating charge and discharge of gas to and from the inside thereof after undergoing a pressure resistance test conducted at a pressure resistance test pressure. The method increases the internal pressure of the high-pressure tank filled with gas to a test pressure that is lower than the pressure resistance test pressure, so that a plurality of AE waveforms is extracted from output waveforms of an AE sensor that detects AE waves generated in the high-pressure tank, and determines whether the high-pressure tank is deteriorated, on the basis of the extracted AE waveforms.
