Abstract

The invention DC60 involves a method for connecting sheets, tubes (10) and pipes (11) in transfer devices. Tubular group heating with the help of rotating friction tools Here the friction tool is moved. Carefully rotated into the open end of the pipe (11) that is surrounded by the tube plate (10) in the axial direction of the pipe. It is pressed against the surface of the pipe (11) in a form where the end of the pipe (12) and the area of the pipe plate (10) surrounding the end of the pipe is plasticized and merged into the welded joint.

Disclaimer (all) which will not appear on the advertisement page: edit 15/07/2015 1.Method for connecting sheets, tubes (10) and tubes (11) in tube group heat transfer equipment. With the help of rotating friction tools Which is unique in that the friction tool is It rotates into the open end of the pipe (11) that is surrounded by the pipe plate (10) in the axial direction of the pipe. And is pressed against the end face of the pipe (12) of the pipe (11) in such a way that the end of the pipe and the area of the pipe plate (10) surrounding the end of the pipe is plasticized and creates a weld joint, which each other 2. The method, corresponding to claim 1, is characterized by a friction tool characterized at the shank (1), where its free end is not provided for clamping, with a cylindrical friction pin (2). ) Which is not consumed during friction welding and by the shoulder ring (3) which is attached to the friction pin (2) and with a larger outer diameter than the friction pin (2) and with the shoulder (4), which Form the transformation The state from the shoulder ring (3) to the friction pin (2) is applied. 3. Method corresponding to claim 2 that is characterized by the shoulder (4) of the shoulder ring (3) of the instrument. Friction used will provide at least one (7) bearing profile. 4. The method corresponding to claim 3 characterized by the bearing profile (7) in the shoulder (4) of the friction tool used is concave when viewed from the friction pin (2). 5. A method corresponding to claim 4 characterized by the bearing profile (7) in the shoulder (4) of the friction tool used has a semicircular, rectangular cross-section. Or triangle 6.Methods for manufacturing tubular heat transfer equipment The characteristics are in the plate (10) and the pipe (11), which are connected by means of a method corresponding to claim 1 ------------------. -----------------------------------------------
