CMT Weld Pool Solidification at 480fps
High-speed footage of a Cold Metal Transfer (CMT) process captured with the Therness Pool Drop Cam — melt pool solidification, droplet transfer, and the direct effect of interval parameters on bead geometry.
Cold Metal Transfer alternates arc phases and controlled short circuits hundreds of times per second — far beyond what a standard 30/60 fps camera can resolve. Filmed at 480fps, this footage shows each droplet detachment and the solidification front of the melt pool, making the effect of CMT interval parameters directly visible. For welding engineers, this is the visual ground truth behind parameter optimization in CMT welding and CMT-based DED/WAAM deposition.
Key Takeaways
- Melt pool solidification behavior at 480fps — slow motion of every CMT cycle.
- Interval parameters visibly change droplet transfer and weld bead geometry.
- Arc-glare filtering keeps the pool, wire tip, and solidification front readable.
- Reference footage for numerical model validation and PQR documentation.
Deploy with Therness
- Pool Drop Cam mounts torch-side and films Full HD up to 480fps.
- Integrated laser-safe lighting suppresses arc glare without external optics.
- USB 3.0 into any HeatCore Basic or Pro server — visual + thermal in one record.
- Frame-accurate evidence for ISO 17637 visual testing and root-cause analysis.
