Abstract: A ground electrode is provided having a ground electrode body, the ground electrode body having an anchored end and a non-anchored end opposite the anchored end. The ground electrode includes a plateau extending from a surface of the ground electrode body adjacent the non-anchored end. In illustrative embodiments, the plateau is formed by removing a portion of the ground electrode body near the non-anchored end. The plateau is configured to be exposed around its periphery. A noble metal tip is fixably attached to the plateau.

Abstract: An electrode for a spark plug includes an electrode tip end. A first weld affixes at least a portion of the noble metal tip to the tip end of the electrode. The noble metal tip has a fold around its periphery. A second weld joins the fold of the noble metal tip to the tip end of the electrode and creates a seal over the first weld.
