ELEMENT FRICTIONALLY WELDABLE TO A TUBE END AND CORRESPONDING WELDING METHOD

摘要

The invention relates to a tubular fluid transporting element which is fixable to a tube end by friction welding and comprises a body (1) wherein a tube end reception area (5) is arranged and provided with the input section (6) of the tube end and a weldable section (9) whose entry is delimited by a welding start-up surface (13.2). The reception area comprises a groove (8) between the input section and a the welding section, which receives a backed part of the tube end during welding and has a wall whose at least one portion forms the start-up surface and a stop edge for the backed part oppositely thereto. A friction welding method is also disclosed.
