1. A device for performing a method for producing a lamination pack, the method comprising cutting laminations from an electric strip or electric sheet; placing the laminations on top of each other to form a lamination stack; connecting the laminations by material fusion to each other by: locally plasticizing a material of the laminations in an edge region of the laminations by generating friction heat by at least one tool; mixing the locally plasticized material, at least of the laminations that are neighboring each other, with the at least one tool; and allowing the plasticized material to cool and fuse the laminations in the edge region to form the lamination pack; the device comprising:
at least one punch press configured to cut the laminations from the electric strip or electric sheet;
at least one receptacle disposed at the at least one punch press and configured to place the laminations directly on top of each other in the at least one receptacle to a lamination stack;
at least one friction stir welding tool, wherein the at least one friction stir welding tool is configured to be rotatably driven about an axis of the at least one friction stir welding tool and configured to move transverse to the axis of rotation, wherein the at least one friction stir welding tool is configured to locally plasticize a material of the laminations in an edge region of the laminations by generating friction heat and connect the laminations of the lamination stack in the edge region by material fusion to each other to the lamination pack.
