Das Schweißen oder Löten yon Kupfer im elektrischen Lichtbogen wurde bisher in der Hauptsache dadurch verhindert, daß an der Schweißnaht in dem Kupfer eine starke Oxydulbildung erfolgte, welche ein gutes Zusammenfügen der zu verbindenden Teile nicht zuließ. Man hat versucht, dieses Verbrennen der Schweißnaht durch Reduktionsmittel zu beheben, und hatte bereits vorgeschlagen, demThe welding or soldering of copper in an electric arc has heretofore been in the The main thing is to prevent strong oxide formation in the copper at the weld seam took place, which did not allow a good joining of the parts to be connected. Tried this burning to fix the weld by reducing agents, and had already proposed the

ίο Schmelzeinsatz Phosphor oder Aluminium beizugeben, ohne jedoch hierbei das erstrebte Ziel zu erreichen. Eingehende Versuche, welche zu dem Zwecke vorgenommen wurden, ein einwandfreies Schweißen von Kupfer zu ermöglichen, haben folgendes gezeitigt.ίο to add fusible link phosphorus or aluminum, but without achieving the desired goal. Incoming attempts which were made for the purpose of enabling perfect welding of copper, have brought about the following.

Als Schmelzeinsatz ist ein stark reduzierendes Metall zu wählen, das mit Kupfer zusammen eine homogene Lösung bildet, so daß auch das Schweißmittel von vornherein mög-A strongly reducing metal should be selected as the fusible link, which is combined with copper forms a homogeneous solution, so that the welding material is also possible from the outset.

ao liehst homogen ist. Ein geringer verbleibender Teil des Reduktionsmittels im Kupfer der Schweißnaht und den angrenzenden Partien darf deren Festigkeitseigenschaften nicht nennenswert beeinträchtigen. Das Metall darf weiter nicht zu leicht verdampfen, damit eine [ Gasentwicklung vermieden bleibt. Seine Verbrennungsprodukte müssen als flüssige Schlakken aus dem Metall austreten.ao is homogeneous. A small amount of the reducing agent remaining in the copper the weld seam and the adjacent parts must not have their strength properties significantly affect. The metal must not evaporate too easily, so that [ Gas development is avoided. Its combustion products must be considered a liquid slag emerge from the metal.

Als ein Schmelzeinsatz, welcher diesen Bedingungen entspricht, hat sich ein solcher ergeben, welcher im wesentlichen aus einem Kupferstab besteht, dem ein Zusatz von 3 bis 8 Prozent Mangan bei 1 bis 3 Prozent Silizium beigegegeben wurde. Schmelzeinsätze, welche eine stärkere Beigabe erhalten, sind nicht brauchbar, weil zuviel Mangan und Silizium in der Schweißstelle zurückbleiben; schwächere Beigaben sind unzureichend. Als besonders wesentlich hat es sich herausgestellt, daß der Manganzusatz sich zum Siliziumzusatz wie etwa 3:1 verhält, da dann das Silizium restlos verbrennt, das Mangan dagegen, welches dem Kupfer nicht schädlich ist, sofern keine allzu großen Konzentrationen erreicht werden, noch etwas zurückbleibt, demnach bis zum Erkalten die Schweißstelle vor Oxydation durch die Luft schützt.A fuse link that complies with these conditions has been found to be which consists essentially of a copper rod with an addition of 3 to 8 percent manganese at 1 to 3 percent Silicon was added. Fusible inserts, which receive a stronger addition, cannot be used because too much manganese and silicon remain in the weld; weaker additions are insufficient. It has turned out to be particularly important that the addition of manganese is related to the addition of silicon like about 3: 1, because then that Silicon burns completely, whereas manganese, which is not harmful to copper if the concentrations are not too high, there is still something left behind, accordingly protects the welding point from oxidation by the air until it cools down.
