Inside a Welding Molten Pool at 480 fps
The arc strikes and a molten pool forms — metal flowing in real time. As the torch travels, the pool freezes into a clean, rippled weld bead.
The weld pool is where quality is decided — pool geometry, symmetry, and freeze rate determine penetration, bead shape, and defect risk before the metal ever cools. At 480 fps you can see exactly what a standard 30/60 fps camera or the naked eye misses: how the pool tracks the torch and how it solidifies pass by pass. That is the same visual signal HeatCore AI scores in real time on a production line.
What you see
- The molten pool forming as the arc strikes.
- Pool geometry and symmetry tracking the torch in real time.
- The freeze front turning liquid metal into a rippled bead.
- Arc glare filtered out so the pool itself stays readable.
