Abstract

The invention relates to an electrode (11) for discharge lamps (10), comprising a pin which is at least partially surrounded by a solid body. The electrode body consists of a wire wrapping (17) and is welded to the pin (18) in one or more fixing points (19, 19', 19'', 19''') by means of laser radiation. The electrode body is therefore solidly connected to the pin (18), forming a robust unit with the same.
