Abstract (en)
[origin: WO2012167972A1] The invention relates to an electrode for an ignition plug, comprising an electrode base material (4) and a precious metal element (5; 50), wherein the precious metal element (5; 50) is fastened to the electrode base material (4) by means of a welded connection (6; 60), wherein the welded connection has a maximum extent (T) perpendicular to a surface (20) of the electrode to which the precious metal element is fastened and the welded connection has a maximum width (B) on the surface (20), and wherein a ratio of the maximum extent (T) to the maximum width (B) is greater than or equal to 3.
