To illustrate the general inspection principle, a typical pulse/echo inspection configuration as illustrated below will be used. Radiographic and ultrasonic weld inspection are the two most common methods of non-destructive testing (NDT) used to detect discontinuities within the internal structure of welds. The general principle of my device consists of sending high frequency vibrations into the part to be inspected, and the determination of the time intervals of arrival of the direct and reflected vibrations at one or more stations on the surface of the part. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. Extracts from the first two paragraphs of the patent for this entirely new nondestructive testing method succinctly describe the basics of such ultrasonic testing. It is used in many industries including steel and aluminium construction, metallurgy, manufacturing, aerospace, automotive and other transportation sectors. Surface must be prepared by cleaning and removing loose scale, paint, etc., although paint that is properly bonded to a surface need not be removed. Interpretation of Ultrasonic Pulse Velocity Test Result: The ultrasonic pulse velocity of concrete primly depends on concrete density and modulus of elasticity property. A full track inspection service is available, which provides an exhaustive report of the location, characteristics and urgency of all defects. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion. In reflection (or pulse-echo) mode, the transducer performs both the sending and the receiving of the pulsed waves as the "sound" is reflected back to the device. Level 2; UTWelds Plate, Pipe and Node. Find out more. Some capability of estimating the size, orientation, shape and nature of defects. Radiographic Interpretation Castings. The indication will occupy a large segment of the time base line. As shown in below figure (left) : A probesends a sound wave into a test material.
