Description
AUSGEGEBEN AM 9. OKTOBER 1920ISSUED ON OCTOBER 9, 1920
Die Schwierigkeit, zwei Aluminiumgegenstände miteinander zu· verschweißen, besteht bekanntlich darin, daß sich das Aluminium bei Erwärmung sofort mit einer Oxydschicht überzieht, die eine innige Verbindung verhindert. Beim Verschweißen dünner Aluminiumdrähte zeigt sich dieser Nachteil in ganz besonderem Maße.There is the difficulty of welding two aluminum objects together It is well known that the aluminum immediately forms an oxide layer when heated covers that prevents an intimate connection. When welding thin aluminum wires this disadvantage is particularly evident.
Nach vorliegender Erfindung wird) dieseAccording to the present invention) this
ίο Schwierigkeit dadurch behoben, daß man die Aluminiumdrähte in einer zweiteiligen Form verschweißt, die elektrisch.· erhitzt wird. Diese Form ist in ihrer Mitte an der Schweißstelle etwas ausgehöhlt. " Die Drähte werden von zwei Seiten einander entgegengeführt und stoßen in der Aussparung zusammen. Sobald hier das Aluminium schmilzt, wird das geschmolzene und teilweise oxydierte Metall aus der eigentlichen! Schweißstelle heraus und in die Aussparung· gedrückt, und unter dem Schütze der so entstehenden Hülle treffen rein metallische Teile der Drähte aufeinander, die sich miteinander verschweißen. Die Oxydschicht sitzt nun außerhalb des eigentlichen Drahtquerschnittes. Nach erfolgter Verschweißung· wird der Strom abgestellt, so daß die Schweißstelle langsam abkühlt.ίο Difficulty resolved by having the Aluminum wires welded in a two-part form that is electrically heated. These The shape is somewhat hollowed out in the middle at the welding point. "The wires are from two sides run towards each other and collide in the recess. As soon Here the aluminum melts, the molten and partially oxidized metal is made up the real one! Welding point pushed out and into the recess, and under the Contactors of the sheath created in this way meet purely metallic parts of the wires, the weld together. The oxide layer is now outside of the actual Wire cross-section. After the welding has taken place, the current is switched off so that the welding point cools down slowly.
Wie Versuche ergeben haben, wird das Ergebnis noch' günstiger, wenn in die Aussparung vor der Verschweißung1 ein Stückchen Aluminium gelegt wird, welches etwas dicker ist als die zu verschweißenden Drähte. Dieses Stückchen wird durch die Schweißhitze geschmolzen, und in seinem Schmelzbade treffen die beiden Drähte aufeinander. In diesem Falle bildet dieses Schmelzbad die Schutzhülle für die zu verschweißenden rein metallischen Drahtenden.As tests have shown, the result is even more favorable if a piece of aluminum, which is somewhat thicker than the wires to be welded, is placed in the recess before welding 1. This piece is melted by the heat of welding, and the two wires meet in its melt pool. In this case, this weld pool forms the protective cover for the purely metallic wire ends to be welded.
Die Verwendung der zweiteiligen Form hat weiter den Vorteil, daß die Drähte genau gegeneinander geführt werden. Die Anwendung des elektrischen Stromes in diesem Zusammenhange gewährt die Möglichkeit, die Schweißhitze in bezug auf ihre Stärke ganz genau zu regeln. Außerdem läßt sich durch den Strom die Schiweißhitze auf einen engbegrenzten Raum beschränken, so· daß benachbarte Drahtteile nicht in Mitleidenschaft gezogen werden.The use of the two-part form has the further advantage that the wires are exactly against one another be guided. The application of the electric current in this connection allows the welding heat to be regulated precisely in terms of its strength. It also lets through restrict the current the welding heat to a narrowly delimited space so that adjacent Wire parts are not affected.
