A welding system (300) is provided, in which two electrodes (E1, E2) are directed at a joint between two work pieces (WP1, WP2) and the electrodes (E1, E2) are energized with DC pulse or AC welding waveforms at a controlled waveform phase angle. The system (300) includes a synchronizing controller (40) to synchronize the welding waveforms, and a work point allocation system (12) provides one or more work point values to the welding machines to provide synergic control of the welding according to a user selected system work point value or parameter. The system and the corresponding method further provide for synchronized work point value modulation for the opposite sides of a dual fillet weld. The system (300) and the method further provide a high energy heat source (310) that directs intense heat at a portion of the weld joint to improve weld penetration.
