Samples of laser‐scratched FeSi3 transformer sheets have been investigated. The investigations were carried out by using the Kossel and EBSD techniques in our self‐designed multifunctional system. The results show residual stress mappings of the cut edges of FeSi3 transformer sheets and their dependence on the cutting process (conventional plate shears, abrasive water‐jet technique, laser cutting).
