Abstract
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.
Claims22
A consumable deposition system;
- said system comprising:
- a power supply which delivers a deposition current to a consumable to deposit said consumable on a workpiece;
- wherein said deposition current has a deposition start portion which starts a deposition of said consumable on said workpiece, and a hot wire portion which follows said start portion;
- wherein said start portion generates an arc between said consumable and said workpiece and said hot wire portion deposits said consumable onto said workpiece where no arc exists between said workpiece and said consumable during said hot wire portion;
- wherein said start portion is maintained for a predetermined threshold, where said predetermined threshold is determined by a controller of said power supply based on at least one input into said power supply;
- and
- wherein said deposition current has a transition portion which transitions said deposition current from said start portion to said hot wire portion.
4 more elements
A consumable deposition method;
- said method comprising:
- generating and delivering a deposition current to a consumable;
- advancing said consumable towards a workpiece to deposit said consumable on said workpiece using said deposition current;
- wherein said generating of said deposition current includes generating a deposition start portion which starts said deposition of said consumable on said workpiece, and where said start portion generates an arc between said consumable and said workpiece to deposit said consumable onto said workpiece,
- determining a predetermined threshold and stopping said start portion after said predetermined threshold;
- generating a transition portion of said deposition current after said start portion is stopped;
- and
- generating a hot wire portion after said transition portion.
