1. A method for simulating welding activity, said method comprising:

  • optically tracking a movement and orientation of a welding tool relative to a welding coupon during a simulated welding operation;

    receiving information related to said movement and orientation of said welding tool;

    modeling, during said simulated welding operation, a simulated welding surface for said welding coupon;

    displaying said simulated welding surface on each of a first display device and a second display device, where said first display device is disposed in a helmet;

    modeling, during said simulated welding operation, a simulated welding arc between an emitting end of said welding tool and said simulated welding surface;

    modeling a simulated weld puddle generated from a simulated deposition of weld material, wherein said simulated weld puddle has a plurality of welding elements, each welding element having a plurality of values, and where at least some of said values change dynamically during said simulated welding operation based on said movement and orientation of said welding tool, wherein said modeling of said simulated weld puddle includes to model real-time molten metal fluidity and real-time heat dissipation characteristics of said weld puddle;

    displaying said simulated welding operation, including said simulated weld puddle and said simulated deposition of said weld material, on either one of or both of said first and second display devices; and

    displaying a simulated completed weld bead on either one of or both of said first and second display devices where said simulated completed weld bead is based on a cooling threshold for a transition of said welding elements from a molten state to a solid state and on said movement and orientation of said welding tool.
