摘要： An apparatus, for non-destructively testing for flaws in materials, having a housing assembly with a rotor and a stator for passing over the testing material, an ultrasonic probe fixed to the stator, and an eddy current probe mounted on the rotor. In operation the rotor rotates the eddy current probe about the ultrasonic probe and an indexing coil on the ultrasonic probe monitors the relative position of the eddy current probe. The rotating eddy current probe generates eddy currents in the testing material such that internal flaws effect the normal feed back to the probe. Changes in this feed back are monitored to determine, in conjunction with the indexing coil, the existence and location of flaws in the testing material. In the preferred embodiment a rotary transformer electromagnetically bonds the rotating eddy current probe to the housing stator. Reflected signals received back by the ultrasonic probe are also monitored to determine the existence of flaws, more readily detected by ultrasonic testing, below the probe.

摘要： An automated system for non-destructive inspection of a weld through the use of ultrasonic waves produced by an electromagnetic acoustic transducer (EMAT). The system includes: a computer control unit; a transport apparatus having a first EMAT for producing an ultrasonic SH shear wave and a second EMAT for receiving an ultrasonic SH shear wave reflected from a weld; a data acquisition unit and a calibration means. The computer control unit, which is in electrical communication with a welding apparatus, the transport apparatus and the data acquisition unit, coordinates the weld test with completion of the weld. An edge detection sensor, which is affixed to the transport apparatus is used to automatically position the transport apparatus for a weld scan and to signal completion of the scan. The system includes an electrostatic shield to protect the second EMAT from electromagnetic and radio frequency interference. Other new and improved electronic features permit certain system components to be remotely located from the transport apparatus and the welding apparatus.

摘要： An apparatus for performing ultrasonic flaw detection, wherein an ultrasonic transmitter transmits a pulse signal having a designated carrier frequency and a designated cycle count to an ultrasonic probe. An ultrasonic receiver receives the echo signal output from the ultrasonic probe. The peak frequency and the frequency bandwidth of the echo signal received by the ultrasonic receiving unit are detected by a signal analysis unit. A transmission control unit designates the carrier frequency and the cycle count of the pulse signal output from the ultrasonic transmission unit so that the detected peak frequency and the detected frequency bandwidth become a flaw detection condition peak frequency and a flaw detection condition frequency bandwidth, respectively.

摘要： A method and apparatus are provided for indicating disbonds in joint regions. A critical bondline region is located between a first material and a second material having a higher acoustic impedance than the first material. A form member having an acoustic impedance which is substantially similar to the first material has a first face which is form fitted to a surface of the first material opposite to and non-parallel with the critical bondline region. The form member has an opposite second face which is shaped to be parallel to the critcal bondline region. Transducers are acoustically coupled to the second face of the form member to generate an ultrasonic tone burst through the acoustically similar form member and first material which is reflected by the critical bondline region. This reflected tone burst is received and a resulting signal is compared with a normal signal for no disbond to determine the presence of an unacceptable disbond.

摘要： The invention relates to a method for determining the threshold value of screens which enable an evaluation of a sound coupling during the ultrasound testing of a series of spot welding joints of a selected type. Initially, a geometrical minimal thickness dMin is established for the spot welding joints. At least one echo of the front surface (entrance echo) is received in addition to one echo of the first reflection on a rear wall of the spot welding joint (first rear wall echo) and at least one further (n-th) rear wall echo. The propagation time tMin of the ultra sound pulse is defined for the path to the front surface to the rear wall and back to the front surface at a minimal thickness dMin and a propagation time tT for the total thickness. A first screen (B1) is set for the signal of the rear wall echo, starting at a moment in time t1S=tE+tMin−tSA and ending at a moment in time t1T=tE+tT+tSE, whereby tSA and tSE are additional small security measures. An n-th screen is correspondingly determined for the n-th rear wall echo. The testing head is oriented differently.

摘要： Formed Laser Sources (FLS) using pulsed laser light for generation of ultrasonic stress waves are combined with air-coupled detection of ultrasound to provide for the hybrid non-contact, dynamic and remote ultrasonic testing of structural materials, especially railroad tracks. Using this hybrid technique, multimode and controlled frequency and wavefront surface acoustic waves, plate waves, guided waves, and bulk waves are generated to propagate on and within the rail tracks. The non-contact, remote nature of this methodology enables high-speed, fill access inspections of rail tracks. The flexibility and remote nature of this methodology makes possible the detection of critical cracks that are not easy, or impossible to detect, with current inspection techniques available to the railroad industry.
