Description

Es ist bekannt, für die Herstellung von \lundstücken der Schweiß- und Sc'hneidgeräte sowie von Brennerdüsen, wie Mehrflammenbrenner, von Lötkolben usw. normales Elektrolvtkupfer zu verwenden. Es ist auch vorgeschlagen worden, das Kupfer durch Messing oder Gußeisen zu ersetzen. Diese Metalle haben jedoch den Nachteil einer geringen Leitfähigkeit, so daß die der Wärme besonders stark ausgesetzten Teile bald verschleißen. Insbesondere sinkt die Standzeit der den Flammen ausgesetzten Mundstückspitzen erheblich herab.It is known that for the production of welding ends and cutting devices as well as torch nozzles, such as multi-flame burners, of soldering irons etc. to use normal electric copper. It has also been suggested that Replace copper with brass or cast iron. However, these metals have the disadvantage a low conductivity, so that those exposed to heat are particularly strong Parts wear out soon. In particular, the service life of those exposed to the flames is reduced Mouthpiece tips down considerably.

Das Bestreben, das Elektroly tkupfer durch andere Metalle zu ersetzen, war in erster Linie durch die verhältnismäßig schlechte 7erspati,lrarkeit des Kupfers im Vergleich zu anderen Buntmetallen, wie z. B. gegenüber Messing, bedingt. Selbst die Verwendung von Elektrolytkupfer genügt weiterhin nicht vollständig den Ansprüchen frei starker Wärmebeanspruchung. So verbiegen sich z. B. aus reinem Kupfer gehämmerte Mundstücke, wenn sie beim Schweißen von Kehlnähten und Hohlräumen einer starkenWärmebeanspruchungausgesetzt sind.The endeavor to replace the electrolyte copper with other metals, was primarily due to the relatively poor rarity of copper compared to other non-ferrous metals, such as B. compared to brass, conditionally. Self the use of electrolytic copper still does not fully meet the requirements free from high thermal stress. So bend z. B. hammered from pure copper Mouthpieces if they are exposed to high heat loads when welding fillet welds and cavities are.

Die Erfindung hat sich die Aufgabe gestellt; die Nachteile der bekannten Schweiß-, Schneid- und Lötgeräte zu vermeiden. Sie besteht darin, (laß die starker Erwärmung ausgesetzten Teile, inshesondere die -Mundstücke, aus einer Legierung mit etwa o,o6% Tellur, Rest Kupfer bestehen. Die erfindungsgemäße Verwendung derartiger Kupferlegierungen hat den Vorteil, daß bei geringem Tellurgehalt bereits eine hervorragende Bearbeitung des Rohmaterials möglich ist und zum anderen auch eine erhebliche Warmfestigkeit lrestelit. Aus d°ti Kupfer-Tellur-Legierungen 'können alle möglichen der starken Erwärmung ausgesetzten Teile, iiisbesondei-e die Mundstücke; Düsen, Zuleitungsrohre, die Lötkolben usw., hergestellt sein.The invention has set itself the task; the disadvantages of the known Avoid welding, cutting and soldering equipment. It consists in (let the stronger Parts exposed to heat, in particular the mouthpieces, are made of an alloy with about 0.06% tellurium, the remainder being copper. The inventive use of such Copper alloys have the advantage that, with a low tellurium content, an excellent Processing of the raw material is possible and on the other hand also a considerable heat resistance lrestelit. All kinds of strong ones can be made from copper-tellurium alloys Parts exposed to heating, iiisbesondei-e the mouthpieces; Nozzles, supply pipes, the soldering iron, etc., be made.
