Description

Zum Löten oder Schweißen von Nickellegierungen, insbesondere des neuerdings häufig verwandten Monelmetalls, welches eine Nickel-Kupfer-Legierung mit geringen Zusätzen anderer Metalle darstellt, wurde bisher als Flußmittel Borsäure und Borax benutzt. Hierbei zeigte sich als nachteilig eine besondere Empfindlichkeit der Löt- oder Schweißnaht gegen Oxydation und Überhitzung. .Die flüssige Schweiße steigt während des Schweißvorganges auf, was auf eine beträchtliche Gasaufnahme aus. der Flamme zurückzuführen ist, und versucht alsdann, beim Erkalten diese Gase auszustoßen. Hierdurch wird eine erhebliche Porosität der Schweißnaht herbeigeführt.For soldering or welding nickel alloys, especially recently often related monel metal, which is a nickel-copper alloy with minor additives other metals, boric acid and borax have been used as fluxes. Here, a particular sensitivity of the soldering or soldering was found to be disadvantageous Weld seam against oxidation and overheating. .The liquid sweat increases during of the welding process, which indicates considerable gas absorption. the flame and then tries to expel these gases when it cools down. Through this a considerable porosity of the weld is brought about.

Nach der Erfindung werden diese >vbel
stände beseitigt, und zwar durch Anwendung eines Flußmittels, welches neben den bekann ten Bestandteilen Borsäure und Borax CaI- ao ciumsalze, Mangan, Titan und Siliciumlegierungen enthält. Es genügt ein relativ geringer Zusatz dieser Bestandteile, um eine gesunde Schweißung herbeizuführen. According to the invention, these are> v bel
stalls eliminated, namely by using a flux which, in addition to the well-known constituents boric acid and borax contains calcium salts, manganese, titanium and silicon alloys. A relatively small addition of these components is sufficient to bring about a healthy weld.
