Schweisselektrode aus austenitischem Chrom-Nickel-Mangan-Stahl
Im Stammpatent Nr. 192713 wurde eine Schweisselektrode aus einem austenitischen Chrom-NickelMangan-Stahl zum Schweissen von nichtaustenitischen Eisen - und Stahllegierungen beschrieben, die aus 0, 08 - 0,'2P/o C, über 1-1, 5% Si, 18-23% Cr, 0, 01-0, 21o Ti und/oder Zr, ferner aus Ni und Mn zusammen in Mengen zwischen 11 und 18%, wobei jedoch der Mn-Gehalt 75-100% des Ni-Gehaltes beträgt, sowie aus Eisen und unvermeidlichen Verunreinigungen besteht.
Die Verwendung dieser Schweisselektrode im blanken Zustand bei den bekannten Schutzgasschweissverfahren wurde u. a. empfohlen.
Der vorliegenden Erfindung liegt nun die Beobachtung zugrunde, dass bei der Verwendung von aus Kohlendioxyd bestehendem oder mehr als 50% Kohlendioxyd enthaltenden Schutzgas ein im Gegensatz zu den Vorschlägen des Stammpatentes nicht ersetzbarer Titangehalt, u. zw. in Mengen zwischen 0, 10 und 0,'2pro unbedingt erforderlich ist und dass gleichzeitig der Kohlenstoffgehalt innerhalb engerer Grenzen, u. zw. zwischen 0, 10 und 0, 15% gewählt werden muss, wenn Porenbildungen vermieden und die werkstoffeigenen Festigkeits- und Zähigkeitswerte mit Sicherheit erreicht werden sollen.
Für Schweissungen in einem Schutzgas, das aus Kohlendioxyd besteht oder mehr als 50% Kohlendioxyd
EMI1.1
Ni und Mn zusammen zwischen 11 und 18%, wobei der Mn-Gehalt 75-100% des Ni-Gehaltes beträgt, und aus Eisen und unvermeidlichen Verunreinigungen besteht.
Zu beachten ist, dass der Kohlenstoffgehalt des Schweissgutes üblicherweise etwas höher liegt als jener der Elektrode. Die Aufkohlung kann bis zu 0, 05% betragen.

Welding electrode made of austenitic chromium-nickel-manganese steel
The parent patent No. 192713 describes a welding electrode made of an austenitic chromium-nickel-manganese steel for welding non-austenitic iron and steel alloys, which is made from 0.08-0.2P / o C, over 1-1.5% Si, 18 -23% Cr, 0, 01-0, 21o Ti and / or Zr, also from Ni and Mn together in amounts between 11 and 18%, but the Mn content is 75-100% of the Ni content, as well as from Consists of iron and inevitable impurities.
The use of this welding electrode in the bare state in the known inert gas welding process was u. a. recommended.
The present invention is based on the observation that when using protective gas consisting of carbon dioxide or containing more than 50% carbon dioxide, a titanium content that cannot be replaced in contrast to the proposals of the parent patent, and the like. between 0, 10 and 0, '2pro is absolutely necessary and that at the same time the carbon content is within narrower limits, u. between 0.10 and 0.15% must be selected if pore formation is to be avoided and the material's own strength and toughness values are to be achieved with certainty.
For welding in a protective gas consisting of carbon dioxide or more than 50% carbon dioxide
EMI1.1
Ni and Mn together between 11 and 18%, the Mn content being 75-100% of the Ni content, and consisting of iron and inevitable impurities.
It should be noted that the carbon content of the weld metal is usually slightly higher than that of the electrode. The carburization can be up to 0.05%.
