Abstract

Apparatuses, systems, and/or methods for providing welding systems or portions of welding systems that provide a tip-retention device that is configured to direct gas radially towards a contact tip.

Claims (24)

1. A welding torch, comprising:

a nozzle including a tip-retention device; and

a contact tip in contact with the tip-retention device, wherein the tip-retention device is configured to direct gas radially away from the contact tip before directing the gas radially towards the contact tip with respect to an axis of the contact tip.

2. The welding torch according to claim 1 , wherein the tip-retention device is configured to receive a gas diffuser and the contact tip, and wherein the gas diffuser includes a seat with a taper that is configured to interface with a rear-facing taper of the contact tip.

3. The welding torch according to claim 2 , wherein the tip-retention device is configured to interface with a forward-facing taper of the contact tip.

4. The welding torch according to claim 1 , wherein the tip-retention device comprises a tip-retention wall configured to direct the gas radially away from the contact tip.

5. The welding torch according to claim 4 , wherein the tip-retention device comprises an annular rim having a leading edge that is configured to direct the gas towards the contact tip.

6. The welding torch according to claim 5 , wherein the tip-retention device includes a channel comprising a first slot on a first side of the tip-retention wall and a second slot on a second side of the tip-retention wall, and wherein the leading edge is configured to protect the channel of the tip-retention device from welding spatter.

7. A nozzle for use with a welding torch, comprising:

a tip-retention device; and

a contact tip in contact with the tip-retention device, wherein the tip-retention device is configured to direct gas radially away from the contact tip before directing the gas radially towards the contact tip with respect to an axis of the contact tip.

8. The nozzle of claim 7 , wherein the tip-retention device is configured to receive a gas diffuser and the contact tip, and wherein the gas diffuser includes a seat with a taper that is configured to interface with a rear-facing taper of the contact tip.

9. The nozzle according to claim 8 , wherein the tip-retention device is configured to interface with a forward-facing taper of the contact tip.

10. The nozzle according to claim 7 , wherein the tip-retention device comprises a tip retention wall configured to direct the gas radially away from the contact tip.

11. The nozzle according to claim 10 , wherein the tip-retention device comprises an annular rim having a leading edge that is configured to direct the gas towards the contact tip.

12. The nozzle according to claim 11 , wherein the tip-retention device includes a channel comprising a first slot on a first side of the tip-retention wall and a second slot on a second side of the tip-retention wall, wherein the leading edge is configured to protect the channel of the tip-retention device from welding spatter.

13. A device for use with a welding torch, comprising:

an annular sidewall surrounding a hollow interior;

a tip-retention wall attached to the sidewall, wherein the tip-retention wall includes a bore configured to fit a contact tip and a locking taper configured to interface with a forward-facing taper of the contact tip so as to retain the contact tip within the bore; and

a channel in fluid communication with the hollow interior, wherein the channel is configured to provide a passage for gas to flow around the tip-retention wall, the tip-retention wall being configured to direct the gas radially away from the contact tip.

14. The device according to claim 13 , wherein the channel comprises a first slot on a first side of the tip-retention wall and a second slot on a second side of the tip-retention wall.

15. The device according to claim 14 , wherein the device further includes an annular rim at a leading edge of the device, wherein the annular rim is configured to direct the gas towards the contact tip, and wherein the annular rim is configured to protect the channel from welding spatter.

16. The device according to claim 13 , wherein the tip-retention wall is configured to protect the channel from welding spatter.

17. The device according to claim 13 , wherein the device is configured to engage a gas diffuser of the welding torch using at least one of a screw thread or a step in the sidewall, wherein the device is configured to direct gas from the gas diffuser towards the contact tip.
