Abstract

The present study considers the capabilities of Eddy current thermography for detection of Edge defects in metal plates. The focus is given on finding the location and dimensions of the defects available at the edge of metal plates. The study is performed on a slab of SA 387 Gr12 (Killed steel), which has wide applications in power plants sector, oil, and chemical Industry as pressure vessels, heat exchangers, industrial boilers, piping industry and in piping support structures. Small cracks in any of the components can lead to catastrophic failures which ask for the elimination of any stress concentrators at the time of manufacturing like Rolling. A study is performed on the sample with defects created at various angles. Similar cracks are also available in rails created because of Rolled Contact Fatigue. So the study will be useful for the detection of defects in rails also. ECT offers further prospects in extending into the area of automation and has specific advantages compared to conventional methods.
