Claims (2)
1. Schutzgas für das Lichtbogenschweißen von Metall, in erster Linie von hochlegierten Stählen, und zwar sowohl von Stählen,
die empfindlich gegen Karburierung sind, als auch von Stählen, die unempfindlich gegen Karburierung sind, einschließlich Kurzlichtbogenschweißen,
Sprühlichtbogenschweißen und Impulslichtbogenschweißen, dadurch gekennzeichnet, daß das Schutzgas Ar, He
und O~ enthält, wobei die 0„-Konzentration im Bereich von 0,5
bis 1,5 % liegt, die Helium-Konzentration im Bereich von 25 bis 40% liegt und der Rest aus Argon besteht.
2. Schutzgas nach Anspruch 1, dadurch gekennzeichnet, daß die 0„-Konzentration im Bereich von 0,9 bis 1,1% liegt, die Helium-Konzentration
im Bereich von 28,5 bis 33% liegt und der Rest aus Argon besteht.
