nicht gasförmigen Schutzstoffnon-gaseous protective substance

Patentiert im Deutschen Reiche vom 18. August 1927 abPatented in the German Empire on August 18, 1927

Es ist bekannt, bei der elektrischen Lichtbogenschweißung den Lichtbogen mit einer Schutzgashülle zu umgeben. Zu diesem Zweck hat man den Schweißdraht durch eine Düse hindurchgeführt, so daß der Lichtbogen innerhalb des diese Düse verlassenden Gasstromes brennt. Wendet man als Schutzgas Stoffe an, die bei normaler Temperatur nicht gasförmig sind, z. B. Methanol, so ist es erforderlich, diese Stoffe zu vergasen.It is known in the electric arc welding the arc with a To surround protective gas envelope. For this purpose one has passed the welding wire through a nozzle so that the arc burns within the gas flow leaving this nozzle. Is used as a protective gas Substances that are not gaseous at normal temperature, e.g. B. methanol, it is necessary to gasify these substances.

Erfindungsgemäß wird die Düse, aus der der Schutzstoff herausbrennt, gleichzeitig zum Vergasen benutzt. Zweckmäßig wird das Zuleitungsrohr für den Schutzstoff in mehrfachen Windungen um die Düse herumgelegt. Der Schutzstoff, z. B. Methanol, wird hierdurch von der Flammenwärme, die beim Schweißen durch die Lichtbogenwärme erhöht wird, so stark erwärmt, daß er gleichmäßig als Gas aus der Düse herausbrennen ao kann.According to the invention, the nozzle from which the protective substance burns out, at the same time used for gasification. That will be useful Inlet pipe for the protective material laid in multiple turns around the nozzle. The protective substance, e.g. B. methanol, is thereby of the flame heat, which increases during welding by the arc heat is heated so much that it burns out evenly as a gas from the nozzle ao can.
