Abstract:
To provide a welding or additive manufacturing dual wire drive system.SOLUTION: A welding or additive manufacturing wire drive system includes a first drive roll having a first annular groove, a second drive roll having a second annular groove, a first welding wire located between the drive rolls in the annular grooves, and a second welding wire located between the drive rolls in the annular grooves. A biasing member biases the first drive roll toward the second drive roll to force the first welding wire to contact the second welding wire. The first welding wire contacts each of a first sidewall portion of the first annular groove, a first sidewall portion of the second annular groove, and the second welding wire. The second welding wire contacts each of a second sidewall portion of the first annular groove, a second sidewall portion of the second annular groove, and the first welding wire. The drive rolls rotate in opposite directions thereby moving the welding wires through the wire drive system.SELECTED DRAWING: None
