Research on the Robotic Arc Welding of a Five-Port Connector

The uncertain factors of welding process, such as the welding distortion, alternate edges in the welded seams and the variable quantity of the gap, would affect the weld appearance and quality directly. For the robotic arc welding of a five-port connector it’s necessary to establish a welding quality control system, which can realize seam tracking and welding formation control. The system captures the visual signals and the voltage signals to realize three-dimensional seam tracking. Furthermore, it stabilize the shape of the weld pool under the conditions of the varied gap and alternate edge.
