1. A simulator for facilitating simulated welding activity, comprising: a logic processor based subsystem operable to execute coded instructions for generating an interactive welding environment in virtual reality space that emulates gas tungsten arc welding (GTAW) activity on a virtual welding coupon, wherein the interactive welding environment simulates a virtual weld puddle on the virtual welding coupon responsive to performing the simulated welding activity in real time; and displaying means operatively connected to the logic processor based subsystem and configured to visually depict the interactive welding environment, including the virtual weld puddle on the virtual welding coupon, in real time.
