Laser welding has long been valued for its accuracy and efficiency, but the introduction of laser scanner welding has elevated the process to a new level. By integrating galvanometer-driven scanners with advanced laser systems, manufacturers can achieve faster, more flexible, and more precise welds compared to traditional methods.
What Is Laser Scanner Welding?
Laser scanner welding uses a galvanometer-based scanning head to rapidly direct a focused laser beam across a workpiece. Instead of moving the entire workpiece or welding head mechanically, the laser beam is steered by mirrors. This significantly reduces cycle times while ensuring pinpoint accuracy.
The result is a process that can handle complex geometries, delicate materials, and demanding production environments.
Key Advantages of Laser Scanner Welding
- High Speed: Beam steering enables weld speeds up to several meters per second, boosting productivity.
- Precision: The narrow, concentrated beam creates fine weld seams with minimal heat-affected zones.
- Flexibility: Suitable for metals, alloys, and even dissimilar materials.
- Automation-Friendly: Easily integrates with robotic arms and automated production lines.
- Reduced Downtime: No need to reposition parts frequently, improving throughput.
