<p>The connection has a thick-walled pipe section i.e. connecting tube (2), with an axial stepped boring (4) that comprises a small aperture (6). The aperture is formed at a region of a front face (5) to be welded, of the section against the boring. A transition (9) between the aperture and another aperture (7) of the stepped boring is guided into a transition region (8) in a stepped manner. The transition region is arranged in such a manner that a wall thickness of the thick-walled pipe section at the transition region is relatively minimum.</p> |
