The invention relates to a device for welding cylinder-shaped and rotatable elements together. An axially displaceable electrode shaft (1) is provided in a rotatably seated pipe shaft (8). The pipe shaft (8) can be rotated with respect to the electrode shaft (1), and a connecting head (4) is provided on one end of the pipe shaft (8), which is equipped with gripper elements (5) for an interchangeable protective chamber (3). Gripper and positioning elements for a fastening cassette (31) provided for the parts (A, B) to be welded together, which is also interchangeable, are arranged in the protective chamber (3). The electrode shaft (1) extends through the connecting head (4) into the protective chamber (3). |
