Beschreibung
Zusammenfassung:	Producing welded connections between inner tubes and tube support plates of a tube bundle for a product-to-product shell-and-tube heat exchanger by means of an auxiliary device is described. A production method includes pressing the end face of a tube support plate against the end face of the inner tubes in the direction of the inner tube longitudinal axes during welding operations with a first form fit, which is effective both radially and axially, immovably fixing the number of inner tubes corresponding to the tube layout pattern to each other by a second, detachable form fit of the auxiliary device, making a circumferential round weld orbitally, starting from the plate inner bore and the tube inner bore, in a single pass and continuously from radially inside to radially outside, and detaching and removing the auxiliary device from the welded tube bundle.
