In this paper, a new method controlling a steady reverse-side bead appearance in the Narrow-Gap One-Side Arc Welding Process by measuring the shunt-current of a coated rod inserted in the I-butt groove is described. It is proved that the shunt-current wave shape shown in a recorded paper corresponds well to the configuration of a reverse-side bead, and relation between shunt-current wave shape and behaviour of molten pool was established. The conclusions are summarized as follows. (1) Shunt-current wave shape corresponds well to the configuration of reverse-side bead. (2) Relative distance (d) between arc point (location of wire) and a head line of a molten pool corresponds well to the state of reverse-side bead. (3) Development of a system controlling the state of reverse-side bead by picking up several factors as mentioned above is expected.
