A method for producing a laminated core is provided in which a plurality of lamination sheets is partially or completely separated from a strip made of a soft magnetic alloy by laser sublimation cutting, the lamination sheets each having a main surface and a thickness d. The main surface of a first of the lamination sheets is stacked on the main surface of a second of the lamination sheets in a direction of stacking and the main surfaces of the first and the second lamination sheets are substance-to-substance joined at a plurality of points by laser welding, a plurality of filler-free joints being formed between the between the first and the second lamination sheets and being entirely surrounded by the main surfaces of the first and the second lamination sheets.
