Abstract

A simulator facilitating virtual welding activity. The simulator may include a logic processor based subsystem operable to generate an interactive welding environment in virtual reality space that emulates welding activity by simulating a virtual weld puddle having dynamic, real time molten metal fluidity and heat dissipation characteristics, responsive to performing a simulated welding activity in real time. The simulator may include a foot pedal device in operative communication with the logic processor based subsystem and configured to affect a characteristic of the virtual weld puddle in real time, responsive to user control of the foot pedal device. The simulator may be configured to track the movements of a mock welding tool and a mock filler wire and determine interaction between the virtual weld puddle, a corresponding virtual welding tool, and a corresponding filler wire in virtual reality space that would result in the welding tool becoming contaminated.

a mock filler wire; and

one or more second sensors configured to facilitate tracking movement of at least a tip of the mock filler wire in real time by communicating data about a temporally changing position of the mock filler wire 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 filler wire touches the mock GTAW tool 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 touching.

3. The system of claim 2, wherein the logic processor based subsystem:

determines when the tip of the mock filler wire simulatively penetrates the simulated weld puddle; and

modifies at least a height of the simulated weld puddle due to the penetration.

The system of claim 1, further comprising a plurality of mock gas flow cups each configured to be attached to and detached from the mock GTAW tool, wherein each mock gas flow cup of the plurality of mock gas flow cups is configured to simulate a unique directing of gas flow out of the mock GTAW tool.
