Fabrication of Eddy Current Probe for SS 304 tube inspection / Fairus Dora Abdul Malek

The final year student of UiTM Mechanical Engineering under supervision of Prof. Madya Noraini Wahab has carried out this project of "Fabrication of Eddy Current Probe For SS 304 Tube Inspection". The important part about this project is to study some basic theory that involve in eddy current testing. As we know, eddy current testing is one of the major Non-Destructive methods for tube testing. It used a localized electrical field that is introduced into a conductive test specimen by electromagnetic induction. Virtually all-conductive materials can be examined for flaws, metallurgical conditions, thinning and conductivity. The technique is quick, versatile, and sensitive, can be noncontacting and is easily adaptable to automation and in site examination. The main purpose of this final year project is to fabricate eddy current probe using parameters obtained from governing equation by choosing the best eddy current signal with the respect to number of coil winding that can be used for testing defects in SS 304 tube. There are numbers of research methodology used in order to complete the project. The very first step is the literature review studies to understand the basic principals of eddy current Non-Destructive testing. The next step is experimental method used to fabricate and analyzed the best eddy current signai from a set of probe that have been fabricated in the laboratory. Prior to the experiment, 4 eddy current probes are fabricated, each having 40,50,60 and 70 numbers of coil turns. All of these probes are differential type of probe.
