Filler containing easily oxidizable elements

摘要

A filler containing easily oxidizable elements such as aluminum, titanium, zirconium, rare earth metals as well as a powder combination containing fluorides and carbonates is used for fusion welding steel, nickel and cobalt alloys and corresponding castings containing easily oxidizable elements. The ratio of the dry weight of all fluorides to the dry weight of the alkaline earth carbonates in the powder combination is at least 2.2:1.
