Advanced device for welding training, based on augmented reality simulation, which can be updated remotely
Advanced device for the welding training based on simulation with Augmented reality and with remote updates that allows the simulation of: all the industrial welding types—s electrode stick (SMAW), MIG/MAG (GMAW, FCAW) and TIG (GTAW)—; all the materials; all the joint types and, also all the welding positions (1Fa 4F, 1G a 6G, 6GR, etc.). It offers an accurate simulation of a real welding equipment thanks to the use of the Augmented Reality technology, which allows the interaction between different elements in several layers. All this is implemented by a monitoring and student evaluating system that allows the teacher to control remotely what is happening in the classroom in real time and without the necessity of being physically present in the training.
