This paper deals with an ECT diagnosis system using network communication. This system consists of an inspection module, a computational m odule and a communication interface module which can visualize some inspection results from the inspection module with ECT and some analys is results from the computation module. Here, three modules are connected through network architecture and communicated each other. Moreov er, an operator can control interactively the inspection and computational modules in order to...

Abstract An eddy current testing (ECT) system has been developed for inspecting weld surfaces of components in the reactor pressure vessel of nuclear plants. The system can be applied to curved surfaces with an ECT array probe, it can discriminat e flaws from other signal factors by using a combination of arrayed coils signal-phase. The system is applied to a mock-up of core internal components and the signal discrimination using the signal-phase clearly separated flaw and noise signals....

1 flexible multi-coil eddy current testing (ECT) probe and a method for measuring the length of flaws have meen developed for inspecting comple x structures in the reactor pressure vessel of nuclear plants. The probe can be applied to curved surfaces that are larger than a curvature rad ius of 20 mm. And we propose the nethod for measuring the flaw length by introducing a decibel drop method of the ECT output signal. From the te st results of various EDM notches using the probe and the measuring method, we...
