Abstract
A process for connecting a molybdenum foil to a lead portion with sufficient strength and reliability in which an expensive binder, such as platinum, platinum clad molybdenum, or the like, is not used. According to the invention, a carbon containing or carbon coated molybdenum part is placed between the molybdenum foil and the molybdenum lead portion and then the two are resistance welded to one another. Furthermore, a hermetically enclosed part of a lamp can be produced by this process.
