摘要： Disclosed is a composite focusing wedge for ultrasonic non-destructive testing/inspection. The composite wedge comprises a base made of machined or cast material, and a lens made of a material which is cast in liquid form and subsequently solidifies. The acoustic velocity in the base material is less than that in the lens material. The castable lens material conforms exactly to a convex machined or cast surface of the base, thereby forming a concave lower surface of the lens. A flat ultrasonic probe is coupled to a planar upper surface of the lens. The minimum distance between the lower concave and upper planar surfaces of the lens is less than one acoustic wavelength in the lens material. The ringdown time of reverberations between the two surfaces is then sufficiently short that there is no interference between the reverberations and signals from sub-surface flaws in the object being tested.

摘要： A method of using a 1.5D array ultrasonic probe as a component of an inspection system intended for different diameter cylindrical parts without mechanical adjustments of the probe is presented. In particular, the method is presented as a way to improve the near surface resolution over an extended range of cylindrical parts diameter and inspection depths/tubes wall thickness with respect to usual 1D arrays of fixed curvature along the elevation axis. The method relies on a customizable concentric firing pattern of the acoustic pulses with respect to the cylindrical part surface, and on adjustment of the aperture size of the said array. The intended effect is to sharpen and minimize the extent of the front wall echo and to optimize the response from an eventual flaw in the inspected range.

摘要： Disclosed is an ultrasonic phased array non-destructive inspection system that includes a PA probe, a conventional PA inspection unit and a refraction angle verification unit. The PA inspection unit is employed to emit ultrasonic angle beams into an AWS IIW Block and to receive a set of corresponding echo signals reflected from the calibration block and to provide time-of-flight (TOF) values corresponding to each angle beam. The refraction angle verification unit then provides a true angle for each of the angle beams based on the ultrasonic and geometric characteristics of the block and the measured TOF values. Other calibration blocks such as the DSC and Nayships blocks can also be used for this purpose.

摘要： Disclosed is a method and system which efficiently and accurately identifies an acoustic wedge by as simple as pressing a button to execute a command for a phased array inspection system, once the wedge is engaged with the system. It is based on the approach to use the time of flight that ultrasonic signals travel in the wedge to measure and calculate critical parameters, such as the wedge acoustic velocity, the wedge or incident angle and the height of the first element of the associated phased array probe above the base of the wedge.

摘要： Disclosed is a phased array ultrasound total focusing method in which the ultrasound energy is transmitted as plane waves and the response signals are processed as plane waves. The processing is adaptively corrected to account for geometric variations in the probes and the part being inspected. Methods are disclosed for measuring the geometric variations of the probes and the part.

摘要： A calibration method for calibrating a phased array probe that is used for testing girth welds for defects. The method utilizes a calibration device on which is defined a series of reflectors that correspond to a series of target zones. The phased array probe is placed via a wedge relative to the calibration device and the phased array probe is configured with an initial set of acoustic parameters which define at least a transmitting aperture, a receiving aperture and a beam steering angle. Using a Full Matrix Capture (FMC) acquisition process and a ray-tracing module, the values of the initial set of acoustic parameters are optimized to evolve a final set of acoustic parameters which the phased array probe utilizes for testing actual devices for weld defects.
