Schweisselektrode
Gemäss einem älteren, jedoch nicht zum Stand der Technik gehörenden Vorschlag ist die Verwendung einer Schweisselektrode, deren Kerndraht 0, 05-0, 21a C (insbesondere 0,05 - 0,12% C), 14 - 22% Cr (insbesondere 16-19% Cr), 78-86% Fe (insbesondere 81-84% Fe) und von allen übrigen Elementen, vor allem den Stabilisierungselementen, wie Titan und Niob, nur Anteile in der Höhe der normalen Verunreinigungen enthält, zur Herstellung kornzerfallsbeständiger Schweissnähte nach dem Lichtbogenschweissverfahren ohne Schutzgas oder unter einatomigen Schutzgasen bekannt.
Es konnte nun festgestellt werden, dass die beschriebenen Elektroden nicht nur bei Schweissung ohne Schutzgas oder unter einatomigen Schutzgasen erfolgreich eingesetzt werden können, sondern auch für eine Schutzgasschweissung mit Mischgasen, wie Argon + cl + 02 bzw. reinem CO, oder H, 0, und für alle übrigen Schmelzschweissverfahren mit Zusatzwerkstoff.
Auch in diesen Fällen war das Ergebnis eine gesunde, rissfreie Schweissnaht, sofern die Elektroden in unstabilisiertem Zustand verwendet wurden.
Gegenstand der Erfindung ist daher die Verwendung einer Schweisselektrode, deren Kerndraht
EMI1.1
wie Titan und Niob, nur Anteile in der Höhe der normalen Verunreinigungen enthält, zur Herstellung kornzerfallsbeständiger Schweissnähte nach dem Lichtbogenschweissverfahren unter Mischgasen, wie Argon + CO2 + 02 oder unter CO2 bzw. H20, sowie für alle Schmelzschweissverfahren mit Zusatzwerkstoff mit Ausnahme des Lichtbogenschweissens ohne Schutzgas oder unter einatomigen Schutzgasen.

Welding electrode
According to an older proposal that does not belong to the state of the art, the use of a welding electrode with a core wire of 0.05-0.21a C (especially 0.05-0.12% C), 14-22% Cr (especially 16- 19% Cr), 78-86% Fe (in particular 81-84% Fe) and of all other elements, especially the stabilizing elements such as titanium and niobium, only contains proportions in the amount of normal impurities, for producing weld seams that are resistant to grain decay Arc welding processes without protective gas or under monatomic protective gases are known.
It has now been found that the electrodes described can be used successfully not only for welding without protective gas or under monatomic protective gases, but also for protective gas welding with mixed gases such as argon + cl + 02 or pure CO, or H, 0, and for all other fusion welding processes with filler metal.
In these cases, too, the result was a healthy, crack-free weld seam, provided the electrodes were used in an unstabilized state.
The invention therefore relates to the use of a welding electrode, its core wire
EMI1.1
such as titanium and niobium, only contains proportions equal to the normal impurities, for producing weld seams that are resistant to grain decay using the arc welding process under mixed gases such as argon + CO2 + 02 or under CO2 or H20, as well as for all fusion welding processes with filler material with the exception of arc welding without shielding gas or under monatomic protective gases.
