Description

Zum Schweißen von Aluminiumguß sind bereits Schweißlote bekannt geworden die aber erhebliche Nachteile aufweisen. Diese bestehen darin, daß einesteils das Schweißlot eine große Dehnfähigkeit besitzt und andernteils muß der zu schweißende Aluminiumguß äußerst stark erwärmt werden, so daß während des Schweißens eine große Dehnung auftritt, die nach dem Erkalten wieder zurückgeht und in vielen FällenFor welding cast aluminum, however, brazing alloys have already become known have significant disadvantages. These consist in the fact that, on the one hand, the welding solder has a large Has elasticity and on the other hand the cast aluminum to be welded must be extremely strong are heated, so that a large elongation occurs during welding, which after the Cold goes back and in many cases

to ein Reißen der Schweißnaht zur Folge hat. Ferner erfordert die verhältnismäßig große Erwärmung des Gußkörpers eine Verschwendung der Heizquelle, z. B. Gas.
Das nach dem neuen Verfahren hergestellte Schweißlot für Aluminiumguß vermeidet nun diese Ubelstände, indem es eine geringe Dehnfähigkeit aufweist und sich bei nur geringer Erwärmung des zu schweißenden Körpers anwenden läßt, so daß dadurch ein Reißen ver-to cause the weld seam to tear. Furthermore, the relatively large heating of the cast body requires a waste of the heating source, e.g. B. Gas.
The welding solder for cast aluminum produced according to the new process now avoids these inconveniences because it has a low elasticity and can be used when the body to be welded is only slightly heated, so that it causes tearing.

Das neue Verfahren besteht darin, daß Kupfer, Eisen und Silizium zusammen bis auf Weißglut gebracht, darin Aluminium zugesetzt und zum Schluß Blei und Zink zugefügt wird. EsThe new process consists in mixing copper, iron and silicon down to white heat brought in, added aluminum and finally added lead and zinc. It

as kann auch Kupfer, Eisen, Silizium und ein geringer Teil Aluminium zusammen auf Weißglut gebracht, und hierauf das übrige Aluminium und zum Schluß Blei und Zink zugefügt werden. Als äußerst zweckmäßig hat sich folgende Zusammensetzung gezeigt, wobei eine Legierung von 100 kg zugrunde gelegt wurde: 6,5 kg Kupfer, 2,0 kg Eisen und 1,5 kg Silizium werden auf Weißglut gebracht und darauf 85,0 kg Aluminium zugesetzt und zum Schluß 0,5 kg Blei und 4,5 kg Zink zugefügt.as can also be copper, iron, silicon and a minor Part of the aluminum brought together to incandescence, and then the rest of the aluminum and finally lead and zinc are added. The following has proven to be extremely useful Composition shown based on an alloy of 100 kg: 6.5 kg Copper, 2.0 kg of iron and 1.5 kg of silicon are brought to white heat and then 85.0 kg of aluminum added and finally added 0.5 kg of lead and 4.5 kg of zinc.

Von den 85,0 kg Aluminium können auch schon vorher etwa 5 kg Aluminium mit Kupfer, Eisen und Silizium auf Weißglut gebracht und nachher der Rest von 80 kg zugesetzt und zum Schluß Blei und Zink zugefügt werden.Of the 85.0 kg of aluminum, about 5 kg of aluminum with copper, Iron and silicon brought to white heat and afterwards the rest of 80 kg was added and used for the Finally lead and zinc are added.
