System for inspecting welded joints in pipe lines by means of ultrasonic waves
TL;DR: In this article, an ultrasonic flaw detection system is used for inspecting circumferentially welded joints in a pipeline, where the ultrasonic probes include crystals for directing and receiving longitudinal waves reflected from the pipe interior surface in order to measure the pipe thickness.
Patent
Device for ultrasonic weld seam testing of longitudinally welded pipes for longitudinal and transversal errors
TL;DR: In this article, an ultrasonic weld seam testing of longitudinally welded pipes for longitudinal and transversal errors is described. But this work is restricted to the case of a single sensor.
Patent
Nondestructive inspection system for laminated products
TL;DR: In this article, an article to be inspected is clamped in a liquid filled tank between a pair of focused transducers, and an ultrasonic pulse is introduced to a cross section of the article from each transducer sequentially.
Patent
Method and device for non-destructive material testing of a test object using ultrasonic waves
TL;DR: In this article, a method for non-destructive material testing of a test object at least solid in some regions by subjecting the test object to ultrasonic waves and capturing the ultrasonic wave reflected within the test objects is presented.
Patent
Ultrasonic tube inspection station for a rapid changeover multi-diameter tube inspection system
TL;DR: A tube inspection station includes a receptacle having walls defining a cavity for holding energy coupling liquid and receiving an object to be inspected in the liquid as discussed by the authors, where the transverse bore intersects with the longitudinal bore and opens at both interior and exterior surfaces of the wall.

System and apparatus for inspecting elongated welds
TL;DR: In this article, an ultrasonic inspection system for inspecting an elongated weld on pipe is described, which includes guide means, such as rollers, for guiding the head along the long seam weld of the pipe.
Patent
Ultrasonic inspection system for welds
TL;DR: In this paper, an ultrasonic inspection system for welds and the like is presented, in which the weld is repeatedly scanned automatically by one or more acoustic transducers each transducer being linked to selected channels of a multi-channel high-speed recorder whereby a record showing the position of any flaws together with an indication of their size is produced.
Patent
Immersion ultrasonic inspection system of the whole surface of rolled flat bar
TL;DR: The immersion ultrasonic inspection system as discussed by the authors inspects the whole surface of a rolled flat bar specimen including flat and end portions thereof by immersing the specimen and probes in water and applying surface wave to the specimen by a plurality of probes disposed in the front and back sides of the specimen at different points with inclination to the surface of the object.
Patent
Method of testing workpieces by means of ultra-sound waves according to the impulse echo method
TL;DR: In this paper, the authors present a method for non-deformation examining workpieces, ESPECIALLY WELDING SEAMS, by means of,ULTRA-SOUND WAVS ACCORDING to the IMPULSE-ECHO METHOD.
