Abstract:
The invention relates to a method for the joining of tube plates (10) and tubes (11) in a tube bundle heat transfer device with the help of a rotating friction tool. Here, the friction tool is rotatingly moved into the open end of a tube (11) surrounded by the tube plate (10) in the axial direction of said tube and pressed against the face of the tube (11) in the manner that the tube end (12) and the region of the tube plate (10) surrounding the tube end are plasticized and merge into a weld joint.
