DUAL FILLET WELDING METHODS AND SYSTEMS

摘要

Methods and systems are provided for dual fillet or T-joint welding, in which two electrodes are directed to opposite sides of a joint between two workpieces and the electrodes are energized with DC pulse or AC welding waveforms at a controlled waveform phase angle. The systems include a synchronizing controller to synchronize the welding waveforms, and a workpoint allocation system provides one or more workpoint values to the welding machines to provide synergic control of the dual fillet welding according to a user selected system workpoint value or parameter. The systems and methods further provide for synchronized workpoint value modulation for the opposite sides of the dual fillet weld.
