Abstract:

In conventional arc welding processes, an electrode only establishes an arc with the workpiece. As such, the current through the electrode and workpiece is the same. As has been demonstrated, this mechanism fundamentally restricts the ability to decouple the heat input and deposition. In order to separately control the mass and heat inputs, double electrode gas metal arc welding (DE-GMAW), which modifies the GMAW by also establishing a second arc from the electrode to an added second electrode, and arcing-wire gas tungsten arc welding (GTAW), which modifies the GTAW by establishing a second arc from the electrode to the welding wire, have been proposed. Since both processes break the conventional arc, this paper refers to them as the divided-arc welding process. While the divided-arc welding process promises a new mechanism to provide an ability to decouple the mass and heat inputs as will be demonstrated in this paper, maintaining a stable arc division is the key to ensuring the promised decoupling ability from this novel arc welding process. Studies are needed to determine how the ability to maintain the arc division is affected by typical variations in manufacturing conditions. Unfortunately, no such studies have been reported. In this paper, the effect from the variation in the distance between the torch and workpiece (simply the torch height) is experimentally studied. Since the variation in the torch height is probably the most commonly encountered variation in welding conditions, such a study is significant in helping to transition the divided-arc welding processes from laboratory to manufacturing.
