METHOD FOR PRODUCING A COMMON CONNECTING OPENING IN TWO COMPONENTS, AT LEAST ONE OF WHICH IS MADE FROM A PLASTICALLY DEFORMABLE MATERIAL

摘要

A method is provided for producing a common connecting opening in two components, at least one of which is made from a plastically deformable material. In the method, at least the edge region of a first prefabricated opening of the first component is softened in order subsequently to introduce a mandrel which displaces the material softened by the heating so that a common connecting opening having a predetermined diameter is obtained.
