The goal of this project is to develop a training system that can simulate the welding process in real-time and give feedback that avoids learning wrong motion patterns for beginning welders and can be used to analyze the process by the teacher afterwards. The system is based mainly on COTS components. A standard PC with a Dual-core CPU and a medium-end nVidia graphics card is sufficient. Input is done with a regular welding gun to allow realistic training. The gun is tracked by an OptiTrack system with 3 FLEX:V100 cameras. The same is also used to track a regular welding helmet to get accurate eye positions for display, which was chosen over glasses for robustness. The display itself is a Zalman Trimon stereo monitor that is laid out horizontally. The software is designed around a main simulation component for solving heat conduction on a grid of simulation points based on local GaussSeidel elimination.
