Abstract: Weldable Cast Nickel Base Superalloy Nickel base superalloys of the type referred to as Waspaloy are rendered weldable by limiting the iron content to about one twentieth of that which is commonly present, adding small amounts of manganese to the alloy and removing the zirconium which is commonly present. In addition, the sulfur, bismuth and lead levels are held to the lowest possible limits, and preferably the aluminum and molybdenum are maintained in the lower half of their normal range. By implementing these alloying strategies, the weldability of the cast material is dramatically improved and for the first time castings of the Waspaloy materials are rendered consistently weldable on a commercial scale.

Abstract: A fushion 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 intermediate layer is an age hardenable nickel superalloy to which intentional additions of manganese have been made. 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.
