Flußmittel zum Löten oder Schweißen von Nickel und NickellegierungenFlux for soldering or welding nickel and nickel alloys

Patentiert im Deutschen Reiche vom 26. Juni 1932 abPatented in the German Empire on June 26, 1932

Als Flußmittel zum Löten oder Schweißen von Nickel und Nickellegierungen wurden bisher Borax und Borsäure benutzt. Es ist schon vorgeschlagen worden, diesen Flußmitteln reduzierende Stoffe bei gleichzeitiger Anwesenheit von Calciumchlorid oder anderen Calciumsalzen zuzugeben, um das Auftreten von Poren in der Schweißung zu verhindern. Überraschenderweise hat sich nun gezeigt, daß durch Zugabe von Oxydationsmitteln zu den bekannten Bestandteilen Borax und Borsäure die Eigenschaften der Schweißung verbessert werden. Zwar ist auch schon die Verwendung von Mangandioxyd als Oxydationsmittel beim Schweißen von Nickel und Nickellegierungen bekannt; die Wirkung wird aber erst vollkommen, wenn gemäß der Erfindung auch noch Halogensalze zugegeben werden. Als Oxydationsmittel können Metalloxyde und Superoxyde, Chromate, Nitrate,As a flux for soldering or welding of nickel and nickel alloys have been Borax and boric acid used. It has been suggested to use these fluxes reducing substances with the simultaneous presence of calcium chloride or others Add calcium salts to prevent pores from appearing in the weld. Surprisingly, it has now been shown that by adding oxidizing agents to the well-known components borax and boric acid improves the properties of the weld will. It is true that manganese dioxide is also used as an oxidizing agent known for welding nickel and nickel alloys; the effect is only complete if according to the invention halogen salts can also be added. Metal oxides can be used as oxidizing agents and super oxides, chromates, nitrates,

Chlorate oder Perchlorate Verwendung finden. Als Halogensalze können sowohl die Halogensalze der Alkali- und Erdalkalimetalle als auch die der Schwermetalle in Anwendung kommen. Eine beispielsweise Zusammen- 25 Setzung des Pulvers ist nachstehend angegeben. "Find chlorates or perchlorates use. Both the halogen salts the alkali and alkaline earth metals as well as those of the heavy metals are used. For example, a joint 25 Settlement of the powder is given below. "
