Abstract
The present disclosure relates to a metal-cored welding wire, and, more specifically, to a metal-cored aluminum welding wire for arc welding, such as Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW). A disclosed metal-cored aluminum welding wire includes a metallic sheath and a granular core disposed within the metallic sheath. The granular core includes a first alloy having a plurality of elements, wherein the first alloy has a solidus that is lower than each of the respective melting points of the plurality of elements of the first alloy.
Claims19
A metal-cored aluminum welding wire, comprising:
- a seamless metallic sheath that comprises an extruded aluminum alloy tube;
- and
- a granular core disposed within the metallic sheath, wherein the granular core includes a first alloy comprising a plurality of elements, wherein the first alloy has a solidus that is lower than each of the respective melting points of each of the elements of the first alloy;
- wherein the solidus of the metallic sheath is at least 5% greater than the solidus of the first alloy;
- wherein the granular core includes additional alloys, wherein each of the additional alloys has a solidus that is higher than the solidus of the first alloy;
- and
- wherein the welding wire comprises less than 5% non-metal components by weight.
A metal-cored aluminum welding wire, comprising:
- a seamless metallic sheath that comprises an extruded aluminum alloy tube;
- and
- a granular core disposed within the metallic sheath, wherein the granular core includes a first alloy comprising a plurality of elements, wherein the first alloy is a eutectic alloy or near-eutectic alloy, wherein the first alloy has a solidus that is lower than each of the respective melting points of each of the elements of the first alloy;
- wherein the granular core includes additional alloys, wherein each of the additional alloys has a solidus that is higher than the solidus of the first alloy;
- wherein the granular core includes a second alloy that is a eutectic or near-eutectic alloy;
- and
- wherein the welding wire comprises less than 5% non-metal components by weight.
The welding wire of 33, wherein the first alloy is a titanium-boron eutectic alloy.
