Twin electrode that made of two coated electrodes used for series arc welding in new process designed for mild steel with heavy rust. In the case of series arc welding with this electrode, arcs are blown outside and make two beads by the cause of electromagnetic force, because current flow reverse direction two coated electrode each other. Arc is ignitioned initially among cores as the result of current flow, and heary rust on the mother metal are melted away for this arc energy afterward series arc initiated between core-mother matel-core. This phenomena has shown ability to welding of automatic non-touch arc starting. The following conculsions could be drown from the observation carried out during this study that prevent arc blow outside and make a bead. 1) A single bead was made by setting copper block at each side of the twin electrode. 2) High quality bead was obtained by proper core distance of a twin electrode and by selection of welding current.
