Abstract

Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen eines Bauteils (20, 40) mittels Innenhochdruck-Umformen aus einem Rohr mit mindestens einem Abschnitt unterschiedlicher Wanddicke. Erfindungsgemäß ist vorgesehen, daß ein zusammengesetztes Rohr (10, 30) verwendet wird, wobei auf ein Innenrohr (11; 31) mit gleichmäßiger Wanddicke zur Erzeugung des mindestens einen Abschnitts unterschiedlicher Wanddicke mindestens ein äußerer Rohrabschnitt (12; 32, 33, 34) aufgeschoben wird und daß die Teile (11, 12; 31, 32, 33, 34) durch den Formgebungsprozeß fest miteinander verbunden werden. Die vorliegende Erfindung betrifft ferner ein derartiges Rohr.
