Abstract
This study explores the welding characteristics of various materials by using an novel welding process-double-sided arc welding (DSAW). The DSAW process uses two series connected arcs to weld the workpiece simultaneously from opposite sides. Due to this arc configuration, the welding current is forced to flow from one arc to the other through the workpiece. In addition to the arc concentration and the increased penetration, this process can naturally increases columnar-to-equiaxed transition (CET) during solidification of the weld pool, and improves solidification microstructures and porosity, which are important to the mechanical properties of the welded joint.
