The cover (1) has a chute channel (2) representing a tube piece, and a flange (3) is formed at one end of the tube piece and projecting outwardly over an outer circumferential surface of the tube piece. A free front side of the flange is connected with the cover by a welding connection, and welding burls (4) are formed at a distance to each other at the front side of the flange. The burls represent the welding connection with regions of the cover over welding nuggets, and have height difference to each other. Tolerance variation of the flange corresponds to respective locations of the burls. Independent claims are also included for the following: (1) a device for welding an airbag cover with a chute channel (2) a method for producing an airbag cover with a chute channel.
