Welder training simulator use the augmented reality technology, so the student will weld on a real workpiece and see the results by computer-generated sensory input through the helmet (welding mask) mounted displays. All of this creates a real-world welding environment (not virtual as other devices do) and improve learning. Also it works with enhanced and very realistic welding-like graphics that will show the welding pool, beam, smoke, sparks, filler material cooling, heat-affected zone, as in the real welding.

It also shows the different types of welding defects so the student can see them and learn why has any of them been caused: cracks, distortion, gas inclusions (porosity), non-metallic inclusions, lack of fusion, incomplete penetration, and undercutting.

Welder training simulator also incorporates different real workpieces (coupons with international standard measures) geometrically prepared in different ways (types of weld joints as butt joint, lap joint, corner joint, edge joint and T-joint) and also pipe welding.

The system identify the workpiece position and activates the parameters that should act as it will happen in real welding, so in the same welding exercise it will work in a different way depending on the workpiece position (horizontal, vertical, 45º, etc.).
