Process for the production of a construction element

摘要

The invention relates to a process for the production of a construction element, in particular an exhaust valve for internal combustion engines, which must meet extremely high or widely varying mechanical and/or thermal and/or chemical requirements, in which the construction element consists of at least two parts, the two parts being formed by different metals or metal alloys and these individual parts being prefabricated and the two parts being mated or adapted to one another.
