Aus wirtschaftlichen Gründen wird im verstärkten Maße die automatische Schutzgasschweißung an austenitischen Chrom-Nickel-Stählen angewandt. Die Hauptschwierigkeit bei der Verwendung dieses Verfahrens besteht unter üblichen Schweißbedingungen in der Bildung der bekannten Warmrisse im Schweißgut, durch welche der Erfolg dieser Arbeitsweise in Frage gestellt wird.For economic reasons, automatic inert gas welding is increasingly being used Austenitic chrome-nickel steels are used. The main difficulty in using this procedure consists in the formation of the known hot cracks in the weld metal under normal welding conditions, through which the success of this working method in Question is asked.
Der Erfindung liegt die Beobachtung zugrunde, daß diese Warmrißbildung durch geeignete Wahl der Zusammensetzung des Schweißzusatzwerkstoffes verhindert werden kann, wobei es keinesfalls notwendig ist, daß die Zusammensetzung des Zusatzdrahtes mit jener des Grundwerkstoffes genau übereinstimmt. Dies gilt selbstverständlich mit der Einschränkung, daß der Grundwerkstoff ein schweißbarer, austenitischer Chrom-Nickel-Stahl sein muß.The invention is based on the observation that this hot cracking through a suitable choice of Composition of the filler metal can be prevented, whereby it is by no means necessary is that the composition of the filler wire exactly matches that of the base material. This of course applies with the restriction that the base material is a weldable, austenitic one Must be chrome-nickel steel.
Erfindungsgemäß können die bestehenden Schwierigkeiten durch Verwendung eines Zusatzdrahtes vermieden werden, der aus 0,05 bis 0,2% Kohlenstoff, 0,7 bis 1% Silicium, 1,5 bis 2,5% Mangan, 24 bis 26% Chrom, 19 bis 21% Nickel, 0,2 bis 1% Titan und/oder Zirkonium, Rest Eisen und unvermeidbaren Verunreinigungen besteht.According to the invention, the existing difficulties by using an additional wire be avoided that consist of 0.05 to 0.2% carbon, 0.7 to 1% silicon, 1.5 to 2.5% manganese, 24 to 26% chromium, 19 to 21% nickel, 0.2 to 1% titanium and / or zirconium, the remainder iron and unavoidable Impurities.
Es ist bemerkenswert, daß es nicht möglich ist, mit molybdänhaltigen Zusatzdrähten, z. B. mit solchen, die 25% Chrom, 20 bis 25% Nickel und 1 bis 2,5% Molybdän enthalten, befriedigende Ergebnisse zu erzielen.It is noteworthy that it is not possible to use molybdenum-containing filler wires, e.g. B. with those containing 25% chromium, 20 to 25% nickel and 1 to 2.5% molybdenum give satisfactory results to achieve.
Gegenstand der Erfindung ist somit die Verwendung eines Zusatzdrahtes für die Schutzgasschweißung, der aus 0,05 bis 0,2% Kohlenstoff, 0,7 bis 1% Silicium, 1,5 bis 2,5% Mangan, 24 bis 26% Chrom, 19 bis 21% Nickel, 0,2 bis 1% Titan und/oder Zirkonium, Rest Eisen und unvermeidbaren Verunreinigungen besteht, für die Herstellung von Verbindungs- oder Auftragsschweißungen an Grundwerkstoffen aus schweißbaren, austenitischen Chrom-Nickel-Stählen. The subject of the invention is thus the use of an additional wire for inert gas welding, that of 0.05 to 0.2% carbon, 0.7 to 1% silicon, 1.5 to 2.5% manganese, 24 to 26% chromium, 19 to 21% nickel, 0.2 to 1% titanium and / or zirconium, the remainder iron and unavoidable impurities exists, for the production of connection or build-up welds on base materials Made of weldable, austenitic chrome-nickel steels.
