Abstract
There is provided a feed material, wherein the feed material has an elongated body that includes an amount of an alloy filler material and an amount of one or more elemental metal additives effective to scavenge at least one tramp element upon melting of the feed material.
Claims20
A welding feed material comprising:
- an alloy filler material and an amount of one or more elemental metal additives effective to scavenge at least one tramp element upon melting of the welding feed material.
A method for reducing tramp elements that contribute to weld cracking during a deposition process, the method comprising:
- introducing a feed material adjacent a surface of an alloy substrate, wherein the feed material comprises an alloy filler material and an amount of one or more elemental metal additives effective to scavenge at least one tramp element upon melting of the feed material;
- melting the feed material and a portion of the adjacent substrate surface to form a melt pool of the feed material;
- reacting the one or more elemental metal additives with one or more tramp elements to form a reaction product;
- removing the reaction product from the melt pool;
- and
- cooling the melt pool to form a desired deposit on the substrate.
