Training to weld using instruments and machines can depend on factors such as accessibility to equipment, material availability, and time consumption for the process. And so, repeatability of the welding process to practice can be limited. By creating a virtual welding lab containing virtual instruments in a 3D environment, can overcome the mentioned factors. The virtual welding lab can be accessed using a VR headset and motion controllers or by a functional computer.

Instruments are reconstructed in 3D space using the concepts of photogrammetry. Photogrammetry is a process of reconstructing an object using the data of images captured from different positions and angles around the object. To create a virtual environment, game engines were used. In this project, there were two microscopes with different interfaces and a welding machine reconstructed, using photogrammetry. The virtual environment built using the game engine allows the user to interact with these instruments, enabling the users to have an immersive learning experience. Using photogrammetry for reconstructing instruments, and game engines to create a virtual environment can be found efficient in building a virtual welding lab, which can assist the students in a better learning experience.
