摘要： The system includes a plurality of individually selectable transmitter and receiver channels, a common controller and a common acquisition unit constructed to operate on the basis of parameters which are furnished to the controller and the unit as input signals. Some of the parameters are held in a memory and are withdrawn on the basis of test identification numbers to set up the acquisition unit. The acquisition unit has a transit time counter and two parallel operating looking window generators and several comparator stages, operating under utilization of such parameters. The data as acquired by a test, are accumulated and processed to determine new parameters, if necessary, and feeding them to the memory. The controller conducts the tests on the basis of sequencing the system through a group of test identification numbers, and provides also launch delay and receiving delays on the basis of externally, updatable parameters.

摘要： A pipe is reeled onto and over a stand having several positioning rollers to serve as reference for the pipe inspection devices. These devices include a plurality of transducers for longitudinal flaw detection arranged in pairs and along opposite sides of the seam, the transducers being in water tanks hung in gimbals on individual swing arms. Four additional transducers for transverse flaw detection are arranged in a tank hung also in gimbals for positioning the tanks so that it engages the seam while the transducers are aligned with the seam. A gimbal hung tank with two edge probing transducers engages lastly the pipe seam.

摘要： An ultrasonic transducer is held in a tubular holder which in turn is axially placed in a mount. A frame depends from a cover of a gimbal mounted container for coupler fluid and the mount is clamped to the frame at an adjustable angle so that the transducer axis always intersects the same point. Ball rollers on the cover position the container in relation to a pipe to be tested so that said point is located on the pipe's surface. The transducer holder has a shoulder onto which one may seat a calibration standard.

摘要： Equipment for ultrasonic testing structural materials includes transducers and test electronics normally operated in sequential test cycles each cycle including the generation of a test pulse to be sent into the test object and subsequently, upon interaction with the test object, return signals (echos) are received and processed, e.g. as to transit time, amplitude, contour, etc. Self-checking is carried out in three phases. One phase uses simulated receiver signals for operatively disconnected transducers, to be processed by the electronics as if they were echos; a second phase uses simulated transducer inputs and analogous processing and a third phase uses a reference body as test body simulation for conduction of "tests". The results of signal processing are compared with reference signals and correlation of deviations and absence of deviations is used to isolate malfunctions.

摘要： Disclosed is a test head for ultrasonic testing of structural materials. The test head includes its own calibration device in the form of a wire or a bore in front of the transducing surface so that a distinguishable calibration echo is always available. This eliminates the need to calibrate the head by using a reference test object.
