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 کاملThe Development of Laser Ultrasonic Visualization Equipment and its Application in Nondestructive Inspection
We have developed a laser ultrasonic visualization(LUV) equipment. It can be used to study the ultrasound propagation in an arbitrary-shaped object, and also be used to the nondestructive inspection of materials and structures. The LUV equipment consists of the hardware and the software. The hardware consists of a pulsed laser, a scanning mirror (galvanometer scanner), an ultrasound sensor, a l...
متن کاملDevelopment of Ultrasonic Wave Nondestructive Inspection Robot without Coupling Medium Using Emat
The ultrasonic wave is applied as an inspection method for the gas-holder and the pipeline in service. In such an inspection, the application of an automatic inspection system is desirable, because a manual inspection is difficult to accomplish perfectly and exactly due to its enormity, a so-called nondestructive inspection robot is then preferable. However, an ultrasonic nondestructive inspect...
