Description

Schweißpaste zum Schweißen von Kupfer und Kupferlegierungen Die bisher beim Schweißen von Kupfer und Kupferlegierungen benutzten Schweißpasten, die gewöhnlich aus Borax und Kupfervitriol bestehen, sind mit Wasser angerührt.Welding paste for welding copper and copper alloys The previously when welding copper and copper alloys used welding pastes that are commonly used consist of borax and vitriol are mixed with water.

Die Erfindung betrifft eine zum Schweißen von Kupfer und Kupferlegierungen bestimmte Schweißpaste, die sich von den bisher bekannten Pasten dieser Art erfindungsgemäß dadurch unterscheidet, daß das Anrühr- bzw. Auflösemittel für ihre Bestandteile nicht aus Wasser, sondern aus mit Guttapercha und Harz gesättigtem Benzol besteht. Die neue Schweißpaste besteht daher vorzugsweise aus einer Mischung von Borax und Kupfervitriol mit einem Zusatz von mit Guttapercha und Harz gesättigtem Benzol.The invention relates to one for welding copper and copper alloys certain welding paste which differs from the pastes of this type known hitherto according to the invention differs in that the mixing or dissolving agent for its components consists not of water, but of benzene saturated with gutta-percha and resin. The new welding paste therefore preferably consists of a mixture of borax and Copper vitriol with the addition of benzene saturated with gutta-percha and resin.

Es hat sich gezeigt, daß die neue Schweißpaste weit besser als die mit Wasser angerührten Pasten reinigend wirkt, die Kupferoxydbildung beim Schweißen entfernt bzw. verhütet und außerdem die Schweißung mit weniger wertvollen Schweißmitteln als bisher ermöglicht.It has been shown that the new welding paste is far better than that Pastes mixed with water have a cleaning effect, the formation of copper oxide during welding removes or prevents and also the welding with less valuable welding agents than previously possible.
