Abstract: A method for producing a metal sheet with a welded-on tube which has at least partially curved sections, wherein the tube is guided by at least one guide element onto the sheet, is pressed thereon with at least one pressure element and is welded thereto at least at some points and wherein the tube is bent to form the curved sections. In order to achieve the welding-on in a simple manner even in the curved sections, it is provided that a bending is carried out in a plurality of discrete steps, wherein in individual steps firstly the tube with the at least one guide element is bent around a last created welding point and thereafter a new welding point is created. Furthermore, the invention relates to a device for carrying out the method.

Abstract: The invention relates to a method for producing a metal sheet (7) with a welded-on tube (6) which has at least partially curved sections, wherein the tube (6) is guided by at least one guide element (2) onto the metal sheet (7), is pressed thereon with at least one pressure element (3) and is welded thereto at least at some points and wherein the tube (6) is bent to form the curved sections. In order to achieve the welding-on in a simple manner even in the curved sections, it is provided according to the invention that a bending is carried out in a plurality of discrete steps, wherein in individual steps firstly the tube (6) is bent with the at least one guide element (2) around a last created welding point and thereafter a new welding point is created. Furthermore, the invention relates to a device (1) for carrying out the method.
