Description
Die Elektroden elektrischer Schweißmaschinen müssen bekanntlich gute elektrische Leitfähigkeit, hohe Härte und geringe Legierungsfähigkeit mit dem Material der zu verschweißenden Werkstücke besitzen. Da die Elektroden elektrischer Schweißmaschinen höherer Leistungen sehr großen mechanischen Drücken ausgesetzt werden, so ist man neuerdings bestrebt, das bisher allgemein verwendete Kupfer durch ein geeigneteres Material zu ersetzen. Man hat bereits versucht, das Kupfer mit anderen Metallen, insbesondere Silber, Wolfram oder Molybdän, zu legieren, um eine Erhöhung der Härte und eine noch geringere Legierungsfähigkeit mit Eisen zu erreichen. Alle diese Versuche haben bisher aber keine vollkommen befriedigenden Resultate gebracht. Entweder erreichte man eine hohe Härte, aber keine ausreichende Leitfähigkeit, oder in den Fällen, in denen sowohl eine ausreichende Härte als auch eine genügende Leitfähigkeit erzielt wurde, ergab sich ein derart hoher Preis, daß an eine wirtschaftliche Verwertung nicht gedacht werden konnte.It is well known that the electrodes of electric welding machines must have good electrical conductivity, high hardness and low alloying ability with the material to be welded Own workpieces. Since the electrodes of electric welding machines are higher Achievements are exposed to very high mechanical pressures, so is one recently endeavors to replace the previously commonly used copper with a more suitable material to replace. Attempts have already been made to combine the copper with other metals, in particular Silver, tungsten, or molybdenum, too, to increase the hardness and an even more alloy to achieve lower alloying ability with iron. All of these attempts have so far but did not produce entirely satisfactory results. Either a high hardness was achieved, but not sufficient Conductivity, or in those cases where both have sufficient hardness as well a sufficient conductivity was obtained, the price was so high that a economic exploitation could not be thought of.
Der Erfindung gemäß wird nun vorgeschlagen, die Elektroden aus einer homogenen Kupfer-Süicium-Legierung herzustellen, wie man sie als Material für kleinere Schalterbontakte bereits benutzt hat; für den Zweck, den die Erfindung erstrebt, ergab sich nun als Besonderheit, daß die Legierung neben einer hohen Härte und einer durchaus genügenden Leitfähigkeit eine außerordentlich geringe Legierungsfähigkeit mit eisenhaltigen Werkstücken besitzt. Es können daher derartig-e Elektroden an Stelle der Kupferelektroden Verwendung finden, da sie nur unwesentlich teurer als diese sind.The invention is now proposed according to the electrodes from a homogeneous Manufacture of copper-silicon alloy, as it is used as a material for smaller switch contacts has already used; For the purpose for which the invention is aimed, there was now a special feature that the alloy in addition to a high hardness and a sufficient conductivity an extraordinary has little ability to alloy with ferrous workpieces. It can therefore such-e Electrodes are used instead of copper electrodes, as they are only insignificant are more expensive than these.
Besonders geeignet sind Legierungen mit einem Siliciumgehalt bis zu 4,5%. Zur Herstellung dieser Legierung empfiehlt es sich, als Rohstoffe Elektrolytkupfer und 500/oiges reinstes Siliciumkupfer zu verwenden und gegebenenfalls andere Zusätze fernzuhalten. 4·>Alloys with a silicon content of up to 4.5% are particularly suitable. To manufacture this alloy, it is advisable to use electrolytic copper and 500% pure silicon copper as raw materials and, if necessary, to keep away other additives. 4 ·>
