Abstract
A method for producing a heat exchange tube having an inner turbulence insert for a heat exchanger may include providing an austenitic heat exchange tube and the turbulence insert. The method may also include inserting the turbulence insert into the austenitic heat exchange tube, brazing the turbulence insert and the austenitic heat exchange tube via induction brazing, and pressing the austenitic heat exchange tube onto the turbulence insert at least one of during the brazing and after the brazing.

A method for producing a heat exchange tube having an inner turbulence insert for a heat exchanger, comprising:
- providing an austenitic heat exchange tube and the turbulence insert;
- inserting the turbulence insert into the austenitic heat exchange tube;
- brazing the turbulence insert and the austenitic heat exchange tube via induction brazing;
- and
- pressing the austenitic heat exchange tube onto the turbulence insert at least one of during the brazing and after the brazing.
A heat exchanger comprising at least one heat exchange tube affixed in an associated tube sheet via a laser-weld connection, the at least one heat exchange tube being produced by:
- providing an austenitic heat exchange tube and a turbulence insert;
- inserting the turbulence insert into the austenitic heat exchange tube;
- brazing the turbulence insert and the austenitic heat exchange tube via induction brazing;
- and
- pressing the austenitic heat exchange tube onto the turbulence insert at least one of during the brazing and after the brazing.
A method for producing a heat exchange tube having an inner turbulence insert for a heat exchanger, comprising:
- providing an austenitic heat exchange tube and the turbulence insert;
- inserting the turbulence insert into the austenitic heat exchange tube;
- brazing the turbulence insert and the austenitic heat exchange tube subject to a protection-gas atmosphere via induction brazing;
- pressing the austenitic heat exchange tube onto the turbulence insert via at least one roller pair at least one of during the brazing and after the brazing.
