Abstract
A method is described for applying a pin made of a spark-erosion-resistant material, in particular of noble metal, onto a electrode base element. In order to achieve a large pin surface exposed to spark erosion, without increased material outlay for the pin, the pin is placed with one end surface onto the electrode base element and welded to it. The welded-on pin is then, by application of a compressive force engaging at the exposed end surface of the pin and directed toward the electrode base element, upset to a larger diameter.
