Description

Verfahren zum Schweißbarmachen von Aluminium. Gegenstand der Erfindung ist ein Verfahren. Aluminium so zu behandeln, daß es sich ohne Schwierigkeit schweißen und auch löten läßt. und zwar indem dem geschmolzenen Aluminium gepulverter Kalk, z. B. gepulverte Muschelschale, unter Umrühren zugesetzt wird. Die Wirkung dieses Zusatzes ist darauf zurückzuführen, daß die in dem Aluminium enthaltene Tonerde sowie andere Verunreinigungen beseitigt werden.Process for making aluminum weldable. Subject of the invention is a procedure. Treat aluminum in such a way that it can weld without difficulty and also lets you solder. by adding lime powdered to the molten aluminum, z. B. powdered clamshell, is added with stirring. The effect of this Addition is due to the fact that the alumina contained in the aluminum as well as other impurities are removed.

Das Aluminium wird eingeschmolzen. Nach dem Abschäumen der flüssigen Masse wird gepulverter kohlensaurer Kalk unter Umrühren zugesetzt und darauf die Masse nochmals abgeschäumt.The aluminum is melted down. After skimming the liquid Powdered carbonate of lime is added to the mass while stirring and then the Skimmed the mass again.

Der kohlensaure Kalk kann z. B. in Form von in entsprechender Feinheit gepulverten Seemuschelschalen zugesetzt werden. Allzu feiner Kalk versagt natürlich obige `Wirkung.The carbonate of lime can, for. B. in the form of in appropriate fineness powdered seashells are added. Lime that is too fine will of course fail above `effect.

Das so behandelte Aluminium kann auch zur Herstellung von Gußstücken benutzt, sowie durch Auswalzen, Pressen oder Ziehen zu Blech, Rohren, Draht usw, verarbeitet werden. Auch bildet das Material ein gut brauchbares Lot für Aluminium bzw. ein Mittel zum Zusammenschweißen beliebiger Teile aus Aluminium, welches nicht nach dem hier beschriebenen Verfahren behandelt worden ist.The aluminum treated in this way can also be used for the production of castings used, as well as by rolling, pressing or drawing into sheet metal, pipes, wire, etc., are processed. The material also forms a useful solder for aluminum or a means for welding together any parts made of aluminum, which is not has been treated according to the procedure described here.

Das Schweißen geschieht z. B. mittels des Autogenverfahrens. Auch zum Löten ist ein Schweißbrenner zu benutzen, da die gewöhnlich zum Löten benutzten Wärmeerzeuger, wie Lötlampen, nicht genügend Hitze entwickeln.The welding is done z. B. by means of the oxy-fuel process. Even a welding torch should be used for soldering, as they are usually used for soldering Heat generators, such as blowtorches, do not generate enough heat.

Die mit dem neuen Material erzeugten Schweiß- und Lötstellen besitzen, wie sich ergeben hat, eine sehr große Festigkeit, welche noch größer ist als die des nicht geschweißten bzw. gelöteten Materials.Have the welding and soldering points created with the new material, as it turned out, a very great strength, which is even greater than that of the non-welded or soldered material.
