Patent-Ansprüche:Patent Claims: 1. Verfahren zum Zusammenschweißen von Röhren mit Hilfe des elektrischen Lichtbogens, dadurch gekennzeichnet, daß die Innenseite der Schweißnaht während des Schweißens durch einen federnden Ring oder einen ähnlichen federnden Körper abgedeckt gehalten wird. 1. Procedure for welding tubes together with the help of an electric arc, characterized in that the inside of the weld seam during the Welding is kept covered by a resilient ring or a similar resilient body. 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß das Innere des Rohres unter der Schweißstelle mit einem wärmeaufnehmenden oder wärmeableitenden Körper ausgefüllt ist.2. The method according to claim 1, characterized in that the interior of the tube under the weld with a heat-absorbing or heat-dissipating body is filled out. 3. Verfahren nach Anspruch 2, dadurch gekennzeichnet, daß der Innenraum des Rohres unter der Schweißstelle mit Sand ausgefüllt ist.3. The method according to claim 2, characterized in that the interior of the Pipe is filled with sand under the weld. 4. Verfahren nach Anspruch 3, dadurch gekennzeichnet, daß die Sandschicht zwischen zwei im Innern der Rohre liegenden Kreisplatten, die durch Bolzen gegeneinander gezogen werden, eingepreßt wird.4. The method according to claim 3, characterized in that the sand layer between two circular plates lying inside the tubes, which are pulled against each other by bolts, is pressed in.
