Abstract
A method for manufacturing a contract arrangement for a vacuum switching tube having a contact carrier and a contact piece joined to the contact carrier in a vacuum using soldering material. The contact carrier is made of electrically highly conductive material, for example, copper, and the contact piece is made of a flame-resistant sintering material containing copper. The contact piece is pressed flat directly onto the contact carrier, generating a gap along the contact surface, and the soldering material is arranged on areas directly bordering the gap of the contact surface between the contact piece and the contact carrier. Subsequently, in a vacuum through the application of heat, the soldering material is brought to the melting point, and the molten soldering material penetrates into the gap of the contact surfaces between the contact carrier and the contact piece.
