Three sensors, one instant: weld pool, thermal image and welding current in sync
One weld seen by three sensors on one time axis. Played at 0.1x, then 0.025x, a single controlled short-circuit cycle lines up frame by frame with its current trace.
What you see
- The weld pool filmed at 480 fps by the PoolDrop high-speed camera.
- The temperature field recorded at 25 fps by the HeatCam thermal camera.
- The welding current sampled at 25 kHz by WeldTrace.
- Playback at 0.1x, then 0.025x: short circuit, arc, retract, each phase matched to its current trace.
How it was recorded
- Real footage from a robotic R&D cell.
- One weld, three sensors, one shared time axis.
- No generated or interpolated frames.
- Each sensor at its own native rate: 480 fps, 25 fps and 25 kHz.
Why synchronisation matters
A current trace on its own says that something happened at a given millisecond; it does not say what the pool looked like at that moment. Video on its own shows the pool but not the electrical cause. Put on the same time axis, a dip or a spike in the current can be checked against the pool image and the thermal image of the same instant, which is what turns a parameter record into evidence. The visual and thermal views come from the PoolDrop and HeatCam welding cameras; the current trace comes from WeldTrace welding parameter monitoring.
