Abstract
Outer molybdenum current conductors of electric lamps having quartz glass lamp envelopes and pinched seals have a corrosion-resistant metal coating. The current conductors have been ground bare at the end which is welded to a molybdenum foil incorporated in the pinched seal. As a result of this it is achieved that the current conductors do not corrode, that the welding electrode upon making the connection to the foil does not stick to the coating, and that upon making the pinched seal the electric contact between the foil and the current conductor is not interrupted.
