Title: LASER WELDED SPARK PLUG ELECTRODE AND METHOD OF FORMING THE SAME
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.
