Abstract

A method for joining a multiplicity of electrical steel laminations to form a steel lamination stack includes stacking electrical steel laminations coated with an electrical steel coating and baking the electrical steel laminations together in the stack by applying pressure and heat. The steel lamination stack to be baked is inserted in a boiler in the form of a pressure vessel. The boiler is hermetically locked and in particular is completely filled with a liquid medium, whereupon the liquid medium is heated to a predetermined temperature, and the electrical steel laminations are baked together for a predetermined duration at a predetermined pressure. A device for carrying out the method is also provided.
