Abstract:

A system and method of hybrid welding a dual fillet weld. The system includes a laser system that leads a first torch and preheats at least one workpiece. The system also includes a first welding power supply that supplies a first welding waveform to a first wire via the first torch. The first welding waveform creates a first arc between the first wire and the at least one workpiece. The system further includes a second welding power supply that supplies a second welding waveform to a second wire via a second torch. The second welding waveform creates a second arc between the second wire and the at least one workpiece. A controller in the system is operatively coupled to the first power supply, the second power supply and the laser system. The controller synchronizes the first welding waveform and the second welding waveform such that welding current pulses of the second welding waveform at the second torch are not in phase with welding current pulses of the first welding waveform at the first torch. The system is set up such that the first arc and the second arc are across from each other on opposite sides of a weld.
