This can trigger some sort of signal, such as a shrill noise. Figure 13.6. 6: A soldier in Iraq uses a metal detector to search for explosives and weapons. (credit: U.S. Army)
WebWeld testing. Simple high frequency eddy current testers have been used for some time to detect toe cracks in ferrous welds. The method has the advantage of being able to detect cracks through paint layers. The disadvantages lie in the high noise levels caused by permeability changes in the weld and lift-off noise from rough cap surfaces. The two major applications of eddy current testing are surface inspection and tubing inspections. Surface inspection is used extensively in the aerospace industry, but also in the petrochemical industry. The technique is very sensitive and can detect tight cracks. Surface inspection can be performed both on ferromagnetic and non-ferromagnetic materials. Tubing inspection is generally limited to non-ferromagnetic tubing and is known as conventiona…
