1. Method for producing a component of an electromechanical transducer that has windings, wherein the method comprises the steps of:
molding a free end of each of two winding-forming conductor pieces which are to be conductively interconnected;
arranging and fixing the two winding-forming conductor pieces to be interconnected in the component of the electromechanical transducer in a configuration intended for a welding process,
wherein the molding, arranging and fixing is carried out in such a way that the two conductor pieces abut one another in the intended configuration and a recess which widens toward the free ends is provided between the two conductor pieces; and,
welding the two conductor pieces to be connected by means of a beam welding process, wherein the beam is introduced into the widening recess so that a conductive weld connection is established which connects the two conductor pieces to be interconnected; and
characterized in that the two conductor pieces to be interconnected each have a conductor cross section that are the same and in that the conductive weld connection has a cross section of at least 80% and at most 140% of the conductor cross section of the conductor pieces.
