Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Metallelektroden für die elektrische Lichtbogenlötung, die mit einem Zusatz von anderen Metallen, wie Nickel, Aluminium 0. dgl., versehen sind. Die beim Aufbringen eines solchen Überzuges bisher verwendeten Verfahren haben den Nachteil, daß es schwierig ist, das richtige Verhältnis der Zusätze sicherzustellen. Hierzu kommt noch das Bestreben der Zusätze, vor oder während der Benutzung von den Elektroden sich zu lösen.The invention relates to a method for producing metal electrodes for electrical Arc soldering with the addition of other metals, such as nickel, aluminum 0. Like., Are provided. Those previously used when applying such a coating Processes have the disadvantage that it is difficult to ensure the correct ratio of additives. Add to this the endeavor of the additives, before or during use to detach itself from the electrodes.

Diese Nachteile werden durch das Verfahren gemäß der Erfindung vermieden, welches darin besteht, daß die Zusatzmetalle durch ein elektrogalvanisches Verfahren auf das Grundmetall aufgebracht werden. Es hat sich nämlich gezeigt, daß eine möglichst innige Vereinigung der Metallzuschläge mit dem Grundmetall in dem erforderlichen Verhältnis erfolgt und das Niederschlagen einer Legierung durch den elektrischen Lichtbogen viel zuverlässiger und wirksamer wird, wenn die Legierung in dem Augenblick des Lötens durch das Zusammenschmelzen der Metallbestandteile erfolgt.These disadvantages are avoided by the method according to the invention, which therein consists that the additional metals by an electroplating process on the base metal be applied. It has been shown that a union that is as intimate as possible the metal surcharges are made with the base metal in the required ratio and that Deposition of an alloy by the electric arc is much more reliable and becomes more effective when the alloy is melted together at the moment of soldering the metal components takes place.

Soll das Verfahren bei Flußeisenelektroden Anwendung finden, so wird dem Grundmetall durch eine Einsatzhärtung vor dem elektrogalvanischen Überziehen noch Kohlenstoff beigefügt. Hierbei ermöglicht die Tiefe des Behälters eine Kontrolle und Regelung des Kohlen-Stoffzusatzes. If the method is to be used with fluoro-iron electrodes, the base metal Carbon was added through case hardening before electroplating. The depth of the container enables the addition of carbon to be monitored and regulated.

Bei Anwendung eines Aluminiumzusatzes für Elektroden aus schweißbarem Stahl ist es wertvoll, daß außerdem noch ein weiterer Zusatz von Aluminiumpulver gegeben wird. Dadurch wird dem beim Löten von Eisen oder Stahl vorhandenen oder sich bildenden Eisenoxyd entgegengewirkt.When using an aluminum additive for weldable steel electrodes, it is valuable to that a further addition of aluminum powder is also given. This is what happens when soldering iron or steel existing or forming iron oxide counteracted.
