A high-speed multipass real-time holographic interferometer is being employed to observe flow patterns of cover gas surrounding a gas tungsten arc welding plasma. This cover gas keeps contaminants from interacting with the molten pool. Commercially available gas cups and original gas cup designs were evaluated in obtaining an optimal flow for the cover gas.
