Latest research presented at the 30th National Welding Academic Conference of China!
Transient behaviors including droplet transfer, molten pool flow, arc plasma and keyhole oscillation in arc welding, laser hybrid welding and metal additive manufacturing only last microseconds, which cannot be captured by traditional low-speed cameras.
This study adopts Revealer high-speed cameras (S1315 / NEO25) combined with synchronous current & voltage acquisition system, establishing a 3D synchronous observation framework linking morphological evolution, electrical signal response and process parameters.
Main research cases covered in this video:
CMT additive manufacturing: Short-circuit transfer dynamics & necking separation process
GTAW/TIG welding: Arc stability quantitative characterization via arc radiation features
Particle-reinforced TIG additive manufacturing: Marangoni flow & molten pool oscillation
The multi-source synchronous diagnosis system provides visualized, quantitative experimental data for welding physical mechanism modeling and intelligent closed-loop process control.
