Abstract
The present disclosure provides a welding electrode and methods of manufacturing the same. The welding electrode can include a composite body having a tip portion and an end portion. The composite body can include a shell defining a cavity through the end portion, the shell comprising a first metal that includes one or more of the following: a precipitation hardened copper alloy, copper alloy, and carbon steel. The composite body can also include a core within the shell, the core extending through the shell from the tip portion to the cavity, the core comprising a second metal that includes dispersion strengthened copper. The core and the shell have a metallurgical bond formed from co-extrusion.
Claims20
A welding electrode, comprising:
- a composite body having a tip portion and an end portion, the composite body including:
- a shell defining a cavity through the end portion, the shell comprising a first metal that includes one or more of the following:
- a precipitation hardened copper alloy, copper alloy, and carbon steel;
- a core within the shell, the core extending through the shell from the tip portion to the cavity, the core comprising a second metal that includes dispersion strengthened copper;
- wherein the core and the shell have a metallurgical bond formed from co-extrusion;
- wherein the core of the welding electrode has a diameter that increases distally from the tip portion toward the cavity.
A method of manufacturing a composite material, comprising:
- providing a composite metal wire having a first end and a second end, the composite wire including a core and a shell surrounding the core, the core and the shell having a metallurgical bond formed from co-extrusion;
- deforming the wire into a first shape such that the first end forms a rounded tip having a truncation;
- deforming the wire from the first shape into a second shape such that a cavity is formed in the second end;
- wherein deforming the wire from the first shape into the second shape pushes the core from the second end toward the first end;
- wherein the shell comprises one of the following:
- a precipitation hardened copper alloy and carbon steel;
- wherein the core comprises dispersion strengthened copper;
- wherein the core has a diameter that increases from the rounded tip toward the cavity.
