Description
Verfahren und Form zur Herstellung einer Schweißverbindung zwischen verschiedenen Metallen, insbesondere Aluminium und Kupfer, durch Stumpfschweißen unter Druck Beim Stumpfschweißen zweier Metalle, insbesondere Aluminium und Kupfer, durch.Zusammenpressen tritt der Nachteil auf, daß die Oxydhäute, die die Trennschicht zwischen den zu vereinigenden Metallen bilden, nicht beseitigt werden. Die Folge davon ist eine ungenügende Verbindung der Metalle.Method and shape for producing a welded joint between various metals, especially aluminum and copper, by butt welding under pressure When butt welding two metals, especially aluminum and copper, The disadvantage arises that the oxide layers that form the separating layer between the metals to be united, not eliminated. The consequence one of these is an inadequate connection between the metals.
Zur Behebung dieses Nachteils wird gemäß der Erfindung das eine; gegebenenfalls angespitzte und von der Oxydliaut durch Abreiben, Abfeilen od. dgl. befreite Metall, im folgenden mit Keil bezeichnet, mit (lern höheren Schmelzpunkt im kalten Zustand in das andere durch Erhitzen zum Erweichen gebrachte Metall hineingedrückt. Hierbei dringt der Keil in jungfräuliches Material des anderen Metalls ein, so daß in diesem die Bildung einer Oxydhaut von vornherein ausgeschlossen wird. Um weiterhin eine Oxydation und vorzeitige Erweichung ödes gesäuberten Keiles während des Preßvorganges zu verhindern, ist letzterer rasch, am besten schlagartig einzuführen. Nach dem Eintreiben des Keiles wird dieser durch das andere Metall erwärmt, so daß je nach der Höhe der Temperatur des zum Erweichen gebrachten Metalls und der Art der Metallpaare eine Verschweißung durch Diffusion im festen Zustand oder durch Bildung einer flüssigen Zwischenschicht erfolgt. Es ist auch mit der Möglichkeit zu rechnen, daß bei Fehlen einer gegenseitigen Löslichkeit im festen Zustand die Verschweißung auf Grund von Ad- häsionskräften eintritt.To overcome this disadvantage, according to the invention, one; Any metal that has been sharpened and freed from the oxide by rubbing, filing or the like, hereinafter referred to as wedge, with a higher melting point in the cold state, is pressed into the other metal that has been softened by heating. The wedge penetrates the virgin material of the other metal, so that the formation of an oxide skin is excluded from the start. In order to prevent further oxidation and premature softening of the barren, cleaned wedge during the pressing process, the latter should be introduced quickly, preferably suddenly the other metal is heated so that, depending on the level of the temperature of the softened metal and the type of metal pairs, welding takes place by diffusion in the solid state or by the formation of a liquid intermediate layer a mutual solubility in the solid state the verse enters häsionskräften due to ad chweißung.
Das neue Arbeitsverfahren kann insbesondere für die Metallpaare Kupfer und Aluminium, Stahl und Aluminium, Stahl und Kupfer od. dgl. verwendet werden. Grundsätzlich ist auch die Verschweißung gleichartiger Metalle möglich, wobei man die zugespitzte Probe kalt läßt, die unbearbeitete und gegebenenfalls vorgebohrte Probe aper erwärmt.The new working method can be used in particular for the metal pairs copper and aluminum, steel and aluminum, steel and copper or the like can be used. In principle, the welding of metals of the same type is also possible, whereby one the pointed specimen leaves cold, the unprocessed and, if necessary, pre-drilled Sample aper warmed.
Für die Durchführung des neuen Arbeitsverfahrens verwendet man vorteilhaft eine ein,seitliches Ausweichen des erwärmten Metalls verhindernde Form, die zugleich zur Führung des !kalten Keiles dient.It is advantageous to use for the implementation of the new working method a form that prevents the heated metal from sideways evasion, which at the same time serves to guide the! cold wedge.
