Carbon steel is an important component in reinforced concrete structures. These composite materials are susceptible to various degradation processes, especially the corrosion of bars. Since they play role stability structures, these structures require periodic inspections verify their physical conditions. Therefore, a nondestructive testing technique proposed that based on electromagnetic induc...

This paper describes a threefold method of testing the performance of an array-based ultrasonic tool for nondestructive testing of spot welds. The tool is described in its capabilities, use, and advantages over existing counterparts. Performance testing is not only described, but results from carrying out the testing are documented as well. The three performance testing methods include the use ...
