Patent abstract
Friction stir welding is enhanced by preheating of the workpiece with an electrical arc, such as an arc applied by a common gas-tungsten arc welding (GTAW) torch. As the arc is moved about a path on the workpiece, it preheats or partially welds the path, with the friction stir welding head following along the path to complete the weld.
