WELDING MATERIAL FOR DISSIMILAR FUSION WELDING OF CAST IRO

摘要

The invention relates to a weld filler metal for the heterogeneous fusion welding of cast iron, in particular spheroidal-graphite cast iron. To solve the problem of obtaining with a weld filler metal, consisting of a nickel-based alloy, welding results which produce completely satisfactory technological characteristics transversely to the welding direction even in the edge area of the welding zone without special heat treatment of the welded parts, the weld filler metal according to the invention, with regard to the weight of the alloy constituents, contains at least 75% Ni, max. 2.0% C, 0.05 to 5.0% Si, 0.1 to 20.0% Mn, 0.5 to 5.0% Ti, Nb/Ta and/or Zr, 2.0 to 20.0% Co and max. 15.0% Fe.
