1. A simulator for facilitating virtual welding activity, comprising: a logic processor based subsystem operable to execute coded instructions for generating an interactive orbital welding environment that emulates welding setup and activity on a section of virtual pipe having at least one virtual weld joint, wherein the interactive welding environment models fluidity of a weld puddle responsive to performing the virtual welding activity in real-time; a virtual dynamic fluid particle emitter which streams a plurality of liquid particles onto a wexel map surface of said virtual weld joint; displaying means operatively connected to the logic processor based subsystem for visually depicting the interactive welding environment, wherein said displaying means depicts the section of virtual pipe and further wherein said displaying means depicts fluidity and heat dissipation characteristics of the weld puddle in real-time by displaying liquid particles comprising said weld puddle and by displaying a magnitude of heat by associating colors with said heat; and wherein said subsystem comprises channels of information in which at least one channel stores a displacement value for any liquefied particles at a specific location and at least one other channel which stores a magnitude of heat at said specific location, and wherein at least one additional channel represents a total of an initial base metal plus said displacement value for liquefied particles which have solidified at said specific location when said magnitude of heat falls below a cooling threshold of said emitted liquid particles; a pendant or hand-held input device for performing setup and virtual welding activity on the at least one virtual weld joint in real time.
