FIELD: car industry.
SUBSTANCE: invention relates to spark plug electrode (1). Spark plug electrode (1) has main part (2) made of the first material and spark-forming element (3) made of the second material, which is designed to create a spark-forming surface of a spark plug. Spark-forming element (3) and main part (2) of the electrode are interconnected with a material closure by weld (4), in the half adjacent to spark-forming element (3) of which, degree of mixing (D) for the first material or for the second material is less than 15 wt. %. The invention also relates to a method for manufacturing spark plug electrode (1) with main part (2) made of the first material and spark-forming element (3) made of the second material, consisting in performing following stages: preparing main part (2) of the electrode and spark-forming element (3), performing the welding process to connect main part (2) of the electrode and spark-forming element (3) to form weld (4), at the same time, welding beam (5) is directed by reflecting means (6) to the junction of main part (2) of the electrode and spark-forming element (3), and weld (4) is created, for the formation of which welding beam (5) is moved along surface (7) of electrode (1) by tilting reflecting means (6).
EFFECT: increase in the service life of the spark plug electrode.
