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.

主权项

1. A consumable deposition system, comprising:
a power supply which provides a current waveform to a consumable to be deposited into a molten puddle on at least one workpiece, said current waveform comprising:
an arc deposition portion which results in an arc between said consumable and said puddle; anda hot wire portion during which a heating current is provided to said consumable and no arc is created between said consumable and said puddle; wherein said power supply includes a controller which determines a desired heat input into said at least one workpiece from said current waveform and said power supply alternates said current waveform between said arc deposition portion and said hot wire portion to control said heat input into said workpiece from said current waveform to maintain said desired heat input.
