Ultrasonic nondestructive inspection of solid objects
Ultrasonic testing (UT) has been used for nondestructive evaluation (NDE) of materials for more than half a century. A number of NDE techniques have been developed and specifi standards have been created for the UT applications in different areas of engineering. UT has two main goals related to inspection of solid objects, firstl , detection and characterization of material discontinuities (fl ...

متن کاملAutomation for Nondestructive Inspection of Aircraft
We discuss the motivation and an architectural framework for using small mobile robots as automated aids to operators of nondestructive inspection (NDI) equipment. We review the need for aircraft skin inspection, and identify the constraints in commercial airlines operations that make small mobile robots the most attractive alternative for automated aids for NDI procedures. We describe the desi...
متن کاملElectromagnetic Acoustic Transducers for Robotic Nondestructive Inspection in Harsh Environments
Elevated temperature, gamma radiation, and geometric constraints inside dry storage casks for spent nuclear fuel represent a harsh environment for nondestructive inspection of the cask and require that the inspection be conducted with a robotic system. Electromagnetic acoustic transducers (EMATs) using non-contact ultrasonic transduction based on the Lorentz force to excite/receive ultrasonic w...
متن کاملSelecting a Nondestructive Testing Method, Part II: Visual Inspection
http://ammtiac.alionscience.com The AMMTIAC Quarterly, Volume 1, Number 3 INTRODUCTION Visual inspection is by far the most common nondestructive testing (NDT) technique [1]. When attempting to determine the soundness of any part or specimen for its intended application, visual inspection is normally the first step in the examination process. Generally, almost any specimen can be visually exami...
