In this thesis, for the quantitative analysis of the arc beads related to electric fire, we used electron backscatter diffraction(EBSD), a measuring device for grain orientation of materials, we compared and analyzed the surface texture of primary and secondary beads according to the difference in cooling rate at ambient temperature. This analysis revealed that the primary beads showed similar distribution at both low and high angles, while the secondary beads showed a higher distribution at low angles than at high angles. The T-test anf F-test statistical showed that there is a large difference between the primary and secondary beads, although not perfect. Thus, EBSD can be used for quantitative analysis of the beads and can be applied to identify beads in the future.
