Abstract
In a process of welding pieces of tubing into films with a central electrode the central electrode is divided to facilitate the welding in a single process. In the case of tools with or without a central electrode, electrode lamellae lying next to one another have a free visual connection between edges lying towards the insert piece to obtain a tight welded joint.
