Abstract
A method of connecting two components () is disclosed, wherein a first component () is connected to a second component () at a connecting point () of the first component (), and wherein a surrounding region (), which surrounds the connecting point (), is heated by electrical resistance heating prior to the two components () being connected, so that the ductility of the first component () in the surrounding region () is increased and the strength is substantially reduced.
