Abstract

The high speed rotating arc process originally developed for NGW-MAG welding has significant features for bead formation, such as decentralization of penetration and formation of concave bead profile. The examination carried out for horizontal fillet welding by this process has proved that the high speed rotating arc process is also suitable for horizontal fillet welding. Foremost, rotating action of the arc prevents hanging of weld bead and forms flat bead surface under high speed welding condition. Another advantage is the function of automatic seam tracking by arc sensor control. Real time and precision guidance can be achieved by detecting arc voltage waveform which changes with the arc rotation.
