First claim
Opening claim text (preview).
The invention claimed is: 1. A welding wire delivery system comprising one or more members configured to expand or contract based on electrical voltage applied to the one or more members, wherein the one or more members comprise a non-rotational actuator configured to engage, disengage, and move a welding wire bidirectionally along a wire delivery path by contacting the welding wire based on the expansion or contraction to cause movement of the welding wire. 2. The welding wire delivery system of claim 1 , wherein the nonrotational actuator is configured to move the welding wire through a welding torch. 3. The welding wire delivery system of claim 1 , wherein the nonrotational actuator is at least partially disposed in a welding torch. 4. The welding wire delivery system of claim 1 , wherein the nonrotational actuator is at least partially disposed in a cable configured to couple with a welding torch. 5. The welding wire delivery system of claim 1 , wherein the nonrotational actuator is at least partially disposed in a wire feeder that delivers the welding wire to a welding torch. 6. The welding wire delivery system of claim 1 , wherein the nonrotational actuator is at least partially disposed along a wire delivery path from a wire supply to an exit end of a welding torch or wire feed tube. 7. The welding wire delivery system of claim 1 , wherein the nonrotational actuator comprises a piezoelectric device. 8. The welding wire delivery system of claim 7 , wherein the nonrotational actuator comprises a piezoelectric walk motor. 9. The welding wire delivery system of claim 7 , wherein the nonrotational actuator comprises a piezoelectric worm drive. 10. The welding wire delivery system of claim 7 , wherein the nonrotational actuator comprises a piezoelectric wave drive. 11. The welding wire delivery system of claim 1 , wherein the nonrotational actuator comprises a shape memory alloy. 12. The welding wire delivery system of claim 1 , wherein the nonrotational actuator comprises a solenoid piston. 13. The welding wire delivery system of claim 1 , wherein the nonrotational actuator comprises a linear actuator or linear motor. 14. The welding wire delivery system of claim 1 , wherein the nonrotational actuator comprises a voice coil actuator. 15. The welding wire delivery system of claim 1 , wherein the nonrotational actuator comprises a wedge-shaped actuator. 16. The welding wire delivery system of claim 1 , wherein the welding wire delivery system comprises a piezoelectric walk motor comprising the one or more members. 17. The welding wire delivery system of claim 1 , wherein the welding wire delivery system comprises a piezoelectric worm drive comprising the one or more members. 18. The welding wire delivery system of claim 1 , wherein the welding wire delivery system comprises a piezoelectric wave drive comprising the one or more members.
