Abstract
A method for producing an electrode device for a spark plug, with the following steps: preparation of an electrode body composed of a first material, the electrode body having a first joining surface; preparation of a precious metal part, which has a second joining surface; placement of the joining surfaces against each other and production of a relative movement between the joining surfaces during which the joining surfaces are pressed against each other with a first force (F) that is less than a force threshold (F); termination of the relative movement and pressing of the joining surfaces against each other for a pressing period (T) with a second force (F) that is greater than the force threshold (F) in such a way that a diffusion from the first and/or second material beyond the joining surfaces takes place; and termination of the pressing together, wherein the relative movement is a linear movement and/or an orbital movement.
