The AQW-3in1 is suitable for fine welding and joining tasks in medical component manufacturing, including ultrasonic knives, needle tubes, puncture needles, stents, stone extraction nets, endoscopic bone (snake bone), and miniature brackets. It supports butt welding, sleeve welding, and row welding applications for small and delicate metal parts.
High precision welding
- Small welding spots down to < Ø200 µm for minimal joint area
- High precision: radial run-out in rotary parts < 10 µm
- Excellent weld appearance: smooth surface, no bumps, pits, discoloration or deformation
- Pneumatic automatic control for precise clamping of thin-walled tubes and compatibility with tube loading/unloading automation
High finishing
This system ensures welds of exceptional surface integrity by tightly controlling laser parameters, beam alignment, and thermal input. It is engineered to produce smooth, consistent joints even on micro-scale structures, reducing post-weld finishing.
Advantages:
- Clean, smooth weld seams without bumps or pits
- Minimal heat-affected zones, preserving material properties
- Highly stable weld quality over repeated cycles
