The applications of electron backscatter diffraction (EBSD) in welding metallurgy are briefly described, By indexing the backscattered high angle Kikuchi patterns, crystallographic informations, e.g. phase identification, preferred orientation, orientation relationships, even coincidence site lattice can be promptly obtained on a SEM based EBSD system. No tedious procedures in specimen preparation are required, Separate characterizations of materiais by X-ray diffraction and microscopy will be simplified and linked. Theory of texture associated with some microtextures determination of HEDW stainiess steel welds using EBSD are reviewed, Hopefully, the methodology of EBSD in welding metallurgy is thus to be established.
