ABSTRACT OF THE DISCLOSURE A fusion welded surfacing process for use with crack prone substrates is described. The process involves the application of an intermediate layer of crack resistant alloy by fusion welding followed by the application of the desired final surfacing alloy by fusion welding. The inter- mediate layer is an age hardenable nickel superalloy to which intentional additions of manganese have been mate. The final surfacing alloy may be of the hardfacing type or may be of a type which imparts corrosion and oxidation resistance to the underlying article.
