Abstract: The invention relates to a joining connection of at least one exhaust-gas-carrying pipe of an internal-combustion engine having a fastening flange which is inserted in its duct and, on its opening edge situated inside the duct, is welded to the duct wall of the flange, and to a process for its manufacture. In order to provide in a simple manner an automating capacity of the manufacture of the joining connection which is reliable with respect to the process, at least one support projection is constructed in an axially position-defined manner on the duct wall. The support projection projects into the duct and the pipe rests directly on the support projection in the plug-in position in the axial direction. The interior wall of the pipe ends flush with the end edge or projects radially beyond it toward the inside.
