METHOD AND SYSTEM TO USE COMBINATION FILLER WIRE FEED AND HIGH INTENSITY ENERGY SOURCE FOR WELDING WITH CONTROLLED ARCING FREQUENCY |
摘要 |
Systems and methods consistent with embodiments of the present invention are directed to depositing a consumable onto a workpiece using a hot-wire welding technique which employs a combination of hot wire and arc welding. The waveform creates arc events during the hot wire welding operation to add/control heat in the welding process. The hot-wire welding process can be used by itself, with a laser or in conjunction with other welding processes. |

1. A consumable deposition system, said system comprising:
a power supply which provides a current waveform to a consumable to be deposited into a molten puddle on a workpiece, said current waveform comprising:
an arc event portion during which at least one current pulse is provided which results in an arc between said consumable and said puddle;a hot wire portion during which a plurality of heating current pulses are provided to said consumable and no arc is created between said consumable and said puddle, where said heating current pulses have a relatively constant peak current level; anda transition portion between said arc event portion and said hot wire portion; wherein each of said heating current pulses has a corresponding heating voltage pulse, and wherein at least some of said heating voltage pulses have a higher voltage than preceding heating voltage pulses in a given hot wire portion of said current waveform such that a final heating voltage pulse in said given hot wire portion is larger than a first heating voltage pulse in said given hot wire portion. |
