System and method for determining weld travel speed
A system and method for determining weld travel speed. In one example, a welding system includes one or more sensors configured to provide a first indication correspond to a welding arc at a first time and to provide a second indication correspond to the welding arc at a second time. The welding system also includes processing circuitry configured to receive the first indication, to receive the second indication, and to determine a weld travel speed based on a weld length of the workpiece and a difference between the first and second times.

The welding system of claim 1 , wherein the first and second sensors each comprise a temperature sensor, an infrared (IR) sensor, a light sensor, a proximity sensor, or a filler metal feed sensor, and wherein the first indication, second indication, or combination thereof, comprises a temperature indication, a light-based indication, or a proximity indication.
3. The welding system of claim 1 , wherein the processing circuitry is configured to receive the sensor distance.
4. The welding system of claim 1 , comprising a feedback device configured to provide to a user a visual feedback, an audible feedback, a haptic feedback, or a combination thereof, corresponding to the weld travel speed during a welding operation.
5. The welding system of claim 1 , wherein the processing circuitry is configured to derive a heat input of a welding operation based on the first and second indications and a weld length.
6. The welding system of claim 1 , wherein at least one of the first sensor or the second sensor comprises a temperature sensor.

10. A method for determining a weld travel speed, comprising:
receiving, using processing circuitry, a first indication corresponding to a welding arc being present at a predetermined first location at a first time, wherein the first indication originated from a first sensor disposed in association with the predetermined first location adjacent to a workpiece or on the workpiece;
receiving, using the processing circuitry, a second indication corresponding to the welding arc being present at a predetermined second location at a second time, wherein the second indication originated from a second sensor disposed in association with the predetermined second location adjacent to the workpiece or on the workpiece; and
determining, using the processing circuitry, the weld travel speed based on a sensor distance representative of a fixed distance between the predetermined first location and the predetermined second location and a difference between the first and second times.

13. The method of claim 12 , wherein the sensor distance is substantially equal to the distance traveled by the welding torch.
14. The method of claim 12 , wherein the sensor distance is different than the distance traveled by the welding torch.
15. The method of claim 10 , comprising receiving a third indication corresponding to the welding arc being present at a predetermined third location on the workpiece at a third time, determining a second weld travel speed based on a second distance traveled by a welding torch that created the welding arc and a difference between the second and third times, and determining an acceleration, a statistical value, or some combination thereof, based on the weld travel speed and the second weld travel speed, wherein the third indication originated from a third sensor.
