Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bisher war es schwierig, nach einem Verfahren, ähnlich dem Widerstandsschweißverfahren, Metalle elektrisch zu löten. Das Hindernis bestand in dem zwischen Lot und zu lötenden Metallteilen befindlichen Lötmittel, das einen Kontakt zwischen Lot und zu lötenden Metallteilen nicht zuließ.So far it has been difficult to use a process similar to resistance welding Electrically soldering metals. The obstacle was the solder between the solder and the metal parts to be soldered, that did not allow contact between solder and metal parts to be soldered.
Erfindungsgemäß wird nun die Lötstelle auf elektrischem Wege so weit vorgewärmt,According to the invention, the solder joint is now electrically preheated to such an extent that
ίο daß Kontakt zwischen Lot und zu lötenden Stücken auftritt, und durch die dann an der Lötstelle auftretende Widerstandswärme die Lötung beendet. Die Figur zeigt eine Vorrichtung zur Ausübung des Verfahrens.ίο that contact between solder and to be soldered Pieces occurs, and by the resistance heat then occurring at the solder joint Soldering finished. The figure shows an apparatus for carrying out the method.
Die zu lötenden Metallteile α und b werden an der Lötstelle mit einem Lötmittel e bestrichen und zwischen die Spannelektroden c und d geklemmt; dann bringt man ein Stück Lot f zwischen α und b und drückt sie zusammen. Eine bewegliche Hilfselektrode g, die beispielsweise an die Spannelektrode d angeschlossen ist, wird nun an α angedrückt, so daß der Stromübergang νοη α nach g vor sich geht und die Kontaktstelle und durch Wärmeleitung die Lötstelle erwärmt. Sobald die Erwärmung genügt, entsteht an der Lötstelle Kontakt zwischen α und b, die Hilfselektrode g wird entfernt, das Lot f beginnt zu fließen, und die Lötung geht unter Zusammendrücken von α und b vor sich.The metal parts α and b to be soldered are coated with solder e at the soldering point and clamped between the tensioning electrodes c and d; then brought to a piece of solder between f and α b, and presses them together. A movable auxiliary electrode g, which is connected, for example, to the clamping electrode d, is now pressed against α , so that the current transfer νοη α to g takes place and the contact point and the soldering point are heated by conduction. As soon as the heating is sufficient, contact is made between α and b at the soldering point, the auxiliary electrode g is removed, the solder f begins to flow, and the soldering takes place while α and b are pressed together.
