Patent ID: 8471449

Claim:
A method for manufacturing a spark plug comprising an inner conductor, an insulator enclosing the inner conductor, a spark plug body enclosing the insulator, and two electrodes, of which the first electrode is a center electrode connected to the inner conductor in an electrically conductive manner, and the second electrode is a ground electrode connected to the spark plug body in an electrically conductive manner, in which a separately prefabricated precious metal component is positioned on one of the electrodes, is thereafter connected to the electrode by way of resistance welding, and is subsequently affixed by way of laser or electron beam welding, so that the precious metal component extends like a heel beyond the electrode surface next to the precious metal component, wherein a ball is used as the precious metal component, and shaping of the precious metal component by stamping is carried out after the resistance welding and before the laser or electron beam welding, thereby reshaping at least a region of the ball protruding from the electrode surface.
