Abstract:
1. A system for hybrid welding a dual fillet weld, said system comprising: a laser system that leads a first torch and preheats at least one of a first workpiece and a second work piece; a first welding power supply that supplies a first welding waveform to a first wire via said first torch to form a first arc between said first wire and at least one of said first workpiece and said second work piece; a second welding power supply that supplies a second welding waveform to a second wire via a second torch to form a second arc between said second wire and at least one of said first workpiece and said second workpiece; a controller operatively coupled to said first power supply, said second power supply and said laser system, said controller synchronizing said first welding waveform and said second welding waveform such that welding current pulses of said second welding waveform at said second torch are not in phase with welding current pulses of said first welding waveform at said first torch, wherein said first arc and said second arc are across from each other on opposite sides of a weld between said first workpiece and said second workpiece.
