二、Welding Advantages & Performance

1. The laser welding torch supports multi-angle welding for complex seams and precision components.
2. High specific energy, minimal thermal deformation, narrow heat-affected zone with deep penetration.
3. Pulsed or continuous laser rapidly transfers surface heat into metal to form uniform weld beads.
4. No electrodes required compared with traditional welding, cutting working time and production cost.
5. Enables welding of internal metal composites inside fully transparent sealed materials.
6. Long-distance laser transmission via fiber optic cable, compatible with computers and robotic arms for fully automatic, ultra-precise intelligent welding.
