A method of applying a pen on a main electrode body

There is provided a method for applying a pin (17) of a spark erosion resistant material, in particular of precious metal to an electrode basic body (16). exposed to achieve a spark erosion large pin surface without increased material cost for the pin (17) of the pin (17) having an end surface (171) on the electrode base body (16) is placed and welded to it. Subsequently, the welded pin (17) by applying to the free end face (172) of the pin (17) acting, to the electrode basic body (16) directed towards the pressing force to a larger diameter compressed.
