METHOD FOR PRODUCING A WELDED JOINT OF SEVERAL PLANE JOINING OTHER TO ANOTHER DETAILS BY Friction Welding WITH THE FOLLOWING BURTIC DEFORMATION AND WELDED JOINT OBTAINED BY THIS METHOD

摘要

1. A method of obtaining a friction welding of flat, adjacent parts (2, 3), held together by means of a connecting element (1, 22, 35, 39), the collar (5, 10, 23) of which rests on the upper part (2 , 28, 32), and the end side of which together with the lower part (3) forms a friction welding zone by rotation and pressure of the connecting element (1, 22, 35, 39), characterized in that after the formation of the friction welding zone in the first stage, at the end of which the rotation of the connecting element (1, 22, 35, 39) ends, in the second stage, after the fitting of the connecting element (1, 22, 39) until the shoulder (5, 10, 23) comes into contact with the upper part (2, 28, 32), apply pressure to the connecting element (1, 22, 35, 39), which presses the bead (5, 10, 23) to the upper part (2, 28, 32) due to its deformation. ! 2. The method according to claim 1, characterized in that the connecting element (1, 22, 35, 39) is carried out through the hole (7, 30, 34) in the upper part (2, 28, 32) until the formation of the friction welding zone on the lower details (3, 29, 33). ! 3. The method according to claim 1, characterized in that the connecting element (1, 22, 35, 39) melts the material of the upper part (2, 28, 32) in its contact area with the end side due to rotation and pressure As a result, a friction welding zone is formed on the lower part (3, 29, 33). ! 4. The friction welding connection obtained by the method according to claim 1 or 2, moreover, as a result of applying pressure to the connecting element (1, 22, 39), at the end of the friction welding process, the collar (5) has such a deformation that ensures its fit to the upper parts (2, 28, 32), and the connection between the upper part (2, 28, 32) and the connecting element
