Description

Paste zum Festlegen von zu lötenden Teilen Die Erfindung bezieht sich auf eine Paste zum Festlegen von zu lötenden Teilen.Paste for setting parts to be soldered The invention relates to on a paste for fixing parts to be soldered.

Wenn es sich darum handelt, Teile, miteinander zu verlöten, besteht die Notwendigkeit, dieselben gegeneinander derart festzulegen, daß sich die bekanntlich nur wenige Zehntelmillimeter breite Lötfuge während des Lötvorgangs von Hand oder im Ofen nicht verschiebt. Man hat sich hierbei auf umständliche Weise so beholfen, daß man die Teile in einer plastischen Masse einbettete und durch zweimaligen Gipsabguß derselben eine feuerfeste, formgetreue Unterlage herstellte, mit der die Teile während des Lötvorgangs fixiert werden konnten.When it comes to parts to be soldered together, there is the need to fix them against each other in such a way that they are known to be only a few tenths of a millimeter wide solder joint during the soldering process by hand or does not move in the oven. One has managed to do this in a cumbersome way, that one embeds the parts in a plastic mass and casts them twice in plaster of paris the same made a refractory, dimensionally accurate base with which the parts during the soldering process could be fixed.

Es ist auch bekannt, die aneinanderzulötenden Flächen mit einem Klebstoff zu bestreichen und aneinanderzudrücken. Man muß dann warten, bis der Klebstoff getrocknet ist. Der Klebstoff ist (als Flußmittel) Teilnehmer des späteren Lötvorgangs, welcher auf die Anwendung ganz bestimmter Verfahren beschränkt ist. Man kann bei Anwendung dieses bekannten Klebstoffs nur entweder autogen schweißen oder das Lot zusammen mit dem Klebstoff-Flußmittel in Pulver- oder fassanierter Form an die Lötstelle heranbringen.It is also known that the surfaces to be soldered together with an adhesive to spread and press together. You then have to wait for the glue to dry is. The adhesive (as a flux) participates in the later soldering process, which is limited to the use of very specific procedures. One can use this known adhesive only either autogenously weld or the solder together with the adhesive flux in powder or cased form to the soldering point bring up.

Demgegenüber wird erfindungsgemäß zur Festlegung miteinander zu verlötender Teile eine Paste verwendet, welche aus Asbest, Talkum und Wasser besteht und erlaubt, auf Grund ihrer feuerfesten Zusammensetzung und vorzüglichen Volumenkonstanz die hiermit fixierten Teile direkt zu löten. Ein weiterer Vorteil der Erfindung besteht darin, daß beim Nacheinanderlöten verschiedener Teile infolge der umhüllend und damit absolut sicheren anstatt wie bei einer Gipsform nur aufliegend möglichen Verankerung mit einem einzigen Lot gearbeitet werden kann, während man bekanntermaßen wegen der Gefahr des Aufgehens einer früheren Lötstelle bei der geringsten mechanischen Einwirkung bisher zu Loten verschiedener Schmelzpunkte greifen mußte. Dasselbe gilt auch für die Durchführung von Reparaturen, wo die genannte Gefahr besonders groß ist, weil man im allgemeinen den Schmelzpunkt des Erstlotes nicht kennt.In contrast, according to the invention, to be soldered to one another for fixing Parts of a paste used, which consists of asbestos, talc and water and allows due to their refractory composition and excellent volume constancy the to solder fixed parts directly with this. Another advantage of the invention is in that when soldering different parts one after the other as a result of the enveloping and This means that the anchoring is absolutely secure instead of just lying on it, as is the case with a plaster mold A single plumb bob can be used while one is known to be due to the risk of an earlier solder joint opening at the slightest mechanical So far, exposure to solders of different melting points had to resort to soldering. The same is true also for carrying out repairs where the risk mentioned is particularly great is because the melting point of the first solder is generally not known.

Zur einfachen Handhabung des Löthilfsmittels werden z. B. die Asbestfasern und Talkum zu Tafeln verpreßt, die stückweise mit Wasser verknetet zur Herstellung der genannten Paste dienen.For easy handling of the soldering aid z. B. the asbestos fibers and talc pressed into tablets, which are kneaded piece by piece with water for production serve the said paste.

Das in dieser Tafelform in den Handel kommende Löthilfsmittel vermeidet die, gesundheitsschädigende Wirkung des losen Asbestpulvers.Avoids the soldering aid that comes on the market in this board form the harmful effects of loose asbestos powder.
