Behavior of the Fusion Hole in Tungsten Inert Gas Thin-Plate Welding

One-side welding with back formation technique is widely used in pressure vessels and the pressure piping industry. Welders provide high importance to the role of the fusion hole in this type of welding. Therefore, the formation and instability of the fusion hole should be studied to realize the welding automation of the one-side welding with back formation process. A visual sensing system is esta...
