VWL (Virtual Welding Lab) is a web-based e-learning course on various welding processes, that includes: machine shop and welding safety; welding symbols; joint design; welding equipment and equipment setup; welder training lessons for the various types of joints; common problems and how to avoid them; inspection and testing; weldability including material science basics and selection of filler materials; and virtual reality welding demonstrations. The VWL includes 3 sub-modules: VWL-SMAW (shielded-metal arc welding), VWL-FCAW (flux cored arc welding), VWL-GMAW (gas metal arc welding) (under development), and VWL-GTAW (gas tungsten arc welding) (under development).
