Objective:
Double-Sided Arc Welding (DSAW) is a novel process invented and developed at the University of Kentucky. The uniqueness of this process lies in its strong penetration capability and its symmetric, hourglass-shaped welds. A shipyard’s preliminary study suggested this process has potential use in minimizing distortion while at the same time improving throughput when making butt welds.
The efforts of this project were aimed at feasibility studies which assessed, determined, and demonstrated the merits of DSAW as a potential arc welding process for distortion minimization and welding production throughput in the shipbuilding environment. The Final Report includes a detailed description of the research and test parameters, evaluation results and recommended actions. A comparison is made against laser and multi-pass methods for mechanical properties, distortion and productivity.
