Title: METHOD AND SYSTEM TO USE COMBINATION FILLER WIRE FEED AND HIGH INTENSITY ENERGY SOURCE FOR WELDING WITH CONTROLLED ARCING FREQUENCY
Abstract:
Systems and methods consistent with embodiments of the present invention are directed to depositing a consumable (140) onto a workpiece (115) using a hot-wire welding technique which employs a combination of hot wire and arc welding. The waveform (500) 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 (120) or in con¬ junction with other welding processes.
