Pressing device comprises a conical sleeve (6) arranged on a welding lens (2) of a welding beam (9) and freely rotating about an axis (7) which is inclined about an angle to the axis (8) of the welding beam. The axis of the welding beam exits close to the inner casing surface of the sleeve. The free front side of the cone of the casing lies on one point close to the welding beam on the flange of the workpiece to be welded. Preferred Features: The free front side of the cone of the casing is crowned. A feed line for protective gas opens into the casing.
