a logic processor based subsystem operable to execute coded instructions for generating an interactive welding environment that emulates a welding activity on a virtual weld joint defined by at least one of a welding coupon and a sample part;
a virtual sequence controller operatively connected to the logic processor based subsystem for implementing a virtual sequence;
a display operatively connected to the logic processor based subsystem for visually depicting the interactive welding environment including the virtual weld joint;
an input device for performing a virtual welding activity on the virtual weld joint in real time; and
a spatial tracker comprising one or more sensors adapted to track movement of the input device in real time for communicating data about the movement of the input device to the logic processor based subsystem,
wherein the virtual sequence includes a plurality of operations to be performed in order, each operation intended to achieve a particular state,
wherein at least one of the operations is a manual operation to be performed by a user, and
wherein at least one of the operations is an automatic operation to be performed by the virtual welding system.
