Abstract

A real-time virtual reality welding system including a programmable processor- based subsystem, a spatial tracker operatively connected to the programmable processor- based subsystem, at least one mock welding tool capable of being spatially tracked by the spatial tracker, and at least one display device operatively connected to the programmable processor-based subsystem. The system is capable of simulating, in virtual reality space, a weld puddle having real-time molten metal fluidity and heat dissipation characteristics. The system is further capable of displaying the simulated weld puddle on the display device in real-time.

Description

[0001] Cross Reference / Incorporation by Reference to Related Applications : This patent application claims priority to US Provisional Patent Application No. 61 / 090,794, filed August 21, 2008, which is hereby incorporated by reference in its entirety. technical field [0002] Certain embodiments relate to virtual reality simulations. More specifically, certain embodiments relate to systems and methods for providing arc welding training in a simulated virtual reality or augmented reality environment using real-time weld puddle feedback, and to welding simulation. Background technique [0003] Learning how to arc weld has traditionally required many hours of instruction, training and practice. There are many different types of arc welding and arc welding processes that can be learned. Students typically learn welding using real welding systems and performing welding operations on real metal workpieces. Such real-world training can tie up scarce welding resources and deplete ...
