PATENTAMT.PATENT OFFICE.
Den Gegenstand vorliegender Erfindung bildet ein Verfahren zur Herstellung von Doubledraht. The subject of the present invention is a process for the production of double wire.
Es ist bekannt, Doubledraht durch Verschweißen in einem Eisenmantel unter Benutzung des infolge der größeren Ausdehnungsfähigkeit des Kernmetalls entstehenden Druckes herzustellen. Doch erfolgte die Erhitzung bisher von außen nach innen, so daß Deckmetall und Mantel Zeit hatten, dem Druck des später durchwärmten Kerns etwas auszuweichen. Bisweilen fand auch ein Abschrecken des erhitzten Ganzen statt, um den Schweißdruck von außen nach innen zu erzeugen.It is known to use double wire by welding it in an iron jacket the pressure created as a result of the greater expandability of the core metal to manufacture. However, the heating has hitherto been carried out from the outside inwards, so that cover metal and Mantel had time to evade the pressure of the core, which was later warmed through. Occasionally there was also a quenching of the heated whole in order to reduce the welding pressure from the outside to the inside.
Demgegenüber besteht die Erfindung darin, daß unter Benutzung des ersten Verfahrens
die Erwärmung der Metalle vom Kernmetall aus elektrisch so schnell erfolgt, daß nicht
Deckmetall und Mantel durch vorzeitige Erhitzung und Ausdehnung ausweichen können.
Infolgedessen sind keine geschlossenen Muffen mit Einlagen mehr nötig. Auch wird die
Schweißung nach j eder Richtung eine vollständige und kann das Preßgut sofort nach
der Schweißung ohne weiteres dem umhüllenden Rohr entnommen werden.
Auf der Zeichnung zeigen:

undIn contrast, the invention consists in that, using the first method, the metals are heated electrically from the core metal so quickly that the cover metal and jacket cannot escape due to premature heating and expansion. As a result, closed sleeves with inserts are no longer necessary. The weld is also complete in every direction and the material to be pressed can be easily removed from the enveloping pipe immediately after the weld.
On the drawing show:

Fig. 2 einen Querschnitt hierzu.Fig. 2 shows a cross section of this.
Ein Stab α bzw. Kern aus einem Edel- oder Unedelmetall wird mit einem Goldblech b umhüllt und das Ganze in ein Eisenrohr c gesteckt, dieses mit einem zweiteiligen Eisenmantel d umgeben und der Mantel gegen Auseinanderfallen der Hälften mittels Drähte e miteinander verbunden. Durch die mit dem Kern a in Verbindung stehenden elektrischen Pole f, f1 wird das Preßgut vom Kernmetall aus elektrisch erhitzt und durch die Ausdehnung des Kernmetalls der Schweißdruck erzeugt.A rod α or core made of a noble or base metal is wrapped in a sheet of gold b and the whole thing is inserted into an iron tube c, this is surrounded by a two-part iron jacket d and the jacket is connected to one another by means of wires e to prevent the halves from falling apart. Due to the electrical poles f, f 1 connected to the core a , the pressed material is electrically heated from the core metal and the welding pressure is generated by the expansion of the core metal.
Da nun der Schweißdruck weder durch Schrumpfung des erhitzten Ganzen infolge Ablöschens in einer Flüssigkeit erzielt wird, noch die Erhitzung des Ganzen nötig wird, so wird eine intensive, tadellose Schweißung mit weit einfacheren Mitteln in viel kürzerer Zeit erzielt.Since now the welding pressure neither by shrinkage of the heated whole as a result of extinguishing is achieved in a liquid, nor is it necessary to heat the whole thing, so an intensive, flawless weld becomes much shorter with far simpler means Time achieved.
