Description

Verfahren zum Löten von beliebigen anderen Metallen als Aluminium, insbesondere hochschmelzenden Metallen, sowie zum Löten von Metallegierungen Im Hauptpatent 72o 629 ist ein Verfahren zum Verlöten von Teilen aus Aluminiumuntereinander oder mit Teilen aus anderen Metallen beschrieben. Das Verfahren besteht darin, daß .die zu verlötenden Körper wenigstens an der Lötstelle während des Aufbringens des Lotmetalls oder während des Lötvorganges in mechanische Schwingungen von bestimmter Frequenz versetzt werden,. Auf diese Weise gelingt @es, haltbare Lötverbindungen unter Anwendung gebräuchlicher Lotmetalle in einfacher Weise herzustellen und dabei genau so vorzugehen, wie bei den bekannten, schon lange .eingeführten Lötverfahren. Gemäß der vorliegenden Erfindung wird das Verfahren nach dem Hauptpatent zur Herstellung von Lötverbindungen zwischen Körpern aus beliebigen, insbesondere leicht oxydierbaren Metallen verwendet. Bei derartigen Körpern war es bisher stets schwierig oder unmöglich, haltbare Lötverbindungen herzustellen, und zwar deshalb, weil an der Oberfläche dieser Körper stets eine mehr oder weniger feine Oxydschicht,eine Fett- oder Schmutzschicht, vorhanden ist, welche das Haften des Lotmetalls an der Oberfläche verhindert. Wird jedoch :die Verbindungsstelle der Körper in rasche mechanische Schwingungen versetzt, wie dies bei dem Verfahren nach der Erfindung geschieht, dann wird offenbar die feine Oxydhaut von der Oberfläche des Körpers losgesprengt, so daß> das Lotinetall unmittelbar mit der metallischen Oberfläche des Körpers in Berührung kominen und an dieser haften kann.Method of soldering any metal other than aluminum, especially refractory metals, as well as for soldering metal alloys Im Main patent 72o 629 is a method for soldering parts made of aluminum to one another or with parts made of other metals. The procedure is that .the body to be soldered at least at the soldering point during the application of the Solder metal or during the soldering process in mechanical vibrations of certain Frequency can be offset. In this way, durable soldered connections are achieved using common solder metals in a simple manner and thereby proceed exactly as with the well-known, long-established soldering process. According to the present invention, the method according to the main patent for manufacture of soldered connections between bodies made of any, in particular easily oxidizable Metals used. With bodies like this it has always been difficult or impossible to make durable soldered connections, because on the surface this body always has a more or less fine layer of oxide, a layer of fat or dirt, is present, which prevents the solder metal from sticking to the surface. Will however: the connection point of the body is set in rapid mechanical oscillations, like this with the procedure happens after the invention, then will apparently the fine oxide skin burst loose from the surface of the body, so that> the solder metal in direct contact with the metallic surface of the body can come and adhere to this.

Das neue Verfahren ist besonders wertvoll für das Löten von Legierungen der verschiedensten :Art. Auch Eisenlegierungen und hochschmelzende Metalle können mit Hilfe dieses Verfahrens gelötet werden. Selbstvers t, indlicli kann dieses Verfahren auch zum Löten v-)n Aluminiumlegierungen Anwendung finden, da diese löttechnisch die bleichen Schwierigkeiten wie reines Aluminium bieten.The new process is particularly valuable for soldering alloys of the most diverse: Art. Iron alloys and refractory metals can also can be soldered using this procedure. Of course, this procedure can be used indlicli can also be used for soldering aluminum alloys, as these are soldering technology which offer pale difficulties like pure aluminum.
