1. A system for facilitating simulated welding activity, comprising: a mock welding coupon; a mock gas tungsten arc welding (GTAW) tool; a logic processor based subsystem operable to execute coded instructions for generating an interactive welding environment that emulates GTAW activity on a simulated welding coupon, which is based on the mock welding coupon, by the mock GTAW tool, wherein the interactive welding environment simulates a weld puddle on the simulated welding coupon responsive to performing the simulated welding activity in real time; a spatial tracking subsystem operatively connected to the logic processor based subsystem and one or more first sensors configured to facilitate tracking movement of at least a tip of the mock GTAW tool in real time by communicating data about a temporally changing position of the mock GTAW tool to the spatial tracking subsystem, wherein the logic processor based subsystem accepts tracking information from the spatial tracking subsystem and determines when the tip of the mock GTAW tool simulatively intersects a surface of the simulated weld puddle during the simulated welding activity, and wherein the logic processor based subsystem is further configured to generate an indication, to be provided to a user, that the mock GTAW tool has simulatively become contaminated due to the intersecting.
