Description

Flußmittel zur Schweißung von Nichteisenmetallen und Edelstählen Die Erfindung behandelt ein Flußmittel und die Herstellung desselben zur Schweißung von Nichteisenmetallen und Edelstählen, wie Chromnickelstähle und rostfreie Chromnickelstähle.Flux for welding non-ferrous metals and stainless steels Invention deals with a flux and the manufacture of the same for welding of non-ferrous metals and stainless steels, such as chrome-nickel steels and stainless chrome-nickel steels.

Die elektrischen Schweißungen von solchen Nichteisenmetallen und Edelstählen wurden bisher hauptsächlich nur mit besonders. zusammengesetzten Metallelektroden, die je nach dem Grundmaterial legiert sind, vorgenommen. Die Beschaffungskosten solcher Elektroden stellen sich verhältnismäßig sehr hoch. Es ist auch schon vorgeschlagen worden, an Stelle dieser besonders zusammengesetzten Metallelektroden eine Kohleelektrode oder eine Metallelektrode in Verbindung mit einem besonderen, der hohen Temperatur entgegenwirkenden Flußmittel zu verwenden, welches die Oberflächenverbrennungen infolge der Einwirkung der hohen Temperatur verhindert sowie eine Korrosionsbeständigkeit aufweist.The electrical welds of such non-ferrous metals and stainless steels were mainly only with special. composite metal electrodes, which are alloyed depending on the base material. The procurement costs such electrodes are relatively very high. It has already been suggested Instead of these specially composed metal electrodes, a carbon electrode or a metal electrode in connection with a special one, the high temperature to use counteracting flux, which the surface burns as a result of the action of high temperature prevents as well as corrosion resistance having.

Das gemäß der Erfindung verwendete Flußmittel besteht aus Natriumsilikat (Na2Si03) oder Kaliumsilikat (K,Si03), Titandioxyd (TiO2) - in Form von reinem Titandioxyd, Rutil oder anderen Titanmineralien - oder Titanmonoxyd (Ti0), Natriumfluorid (Na2F2) oder Kaliumfluorid (KJ2) und Calciumcarbonat (CaCo3) oder Calciumoxyd (Ca0) oder Strontiumcarbonat (Sr CO.) oder Strontiumoxyd (Sr 0) oder Bariumcarbonat (BaC03) öder Bariumoxyd (Ba0).The flux used according to the invention consists of sodium silicate (Na2Si03) or potassium silicate (K, Si03), titanium dioxide (TiO2) - in the form of pure titanium dioxide, rutile or other titanium minerals - or titanium monoxide (Ti0), sodium fluoride (Na2F2) or potassium fluoride (KJ2 ) and calcium carbonate (CaCo3) or calcium oxide (Ca0) or strontium carbonate (Sr CO.) or strontium oxide (Sr 0) or barium carbonate (BaC03) or barium oxide (Ba0).

Versuche haben beim Schweißen von Edelstählen sowie Nichteisenmetallen mit dem Kohlelichtbogen einwandfrei -ergeben, dafi bei folgender -Zusammensetzung des Flußmittels Experiments in welding stainless steels as well as non-ferrous metals with the carbon arc have shown flawlessly, with the following composition of the flux
