Using the WeldTrainer welding simulator to prepare students for practical exercises

The usefulness of WeldTrainer for learning welding torch manipulation and preparing for real MIG/MAG bead-on-plate practice was assessed. The study involved 70 first-year students at Rzeszów University of Technology, divided into two subgroups of 35 who completed VR and practical exercises in opposite sequences. Each student performed three passes in each environment. Torch-to-workpiece distance, torch angles, travel speed and path straightness were observed. Anonymous questionnaires were collected after both exercises and supplemented by observations and an experienced welder’s opinion. VR was considered useful by 85.7% of participants. Safety and opportunities for repeated practice received the highest ratings. Students who started with VR reported less apprehension about real bead-on-plate practice; this qualitative observation does not demonstrate improved bead quality. The expert identified limitations in reproducing physical sensations and providing weld pool information. WeldTrainer can support initial training when complemented by real welding practice.
