To choose the right laser welding machine, consider factors like the power output, material type, production volume, and whether you need handheld, platform automatic, or robotic arm-based systems.
Choosing the right laser welding machine can be a challenge due to the wide range of options available. Here are the key considerations to help you make the best decision:
Power Output
Laser welding machines come in a range of power output12, from 1.5kW to 6kW. The power you need depends on the material you’re welding and the thickness of the parts. For example, a 1.5kW machine is ideal for thin sheets and small parts, while a 6kW machine is suited for thick, heavy-duty applications.
Material Type and Thickness
The type and thickness of the material play a significant role in determining which machine to choose. Thicker materials require higher power output, so if you're working with metal alloys or other tough materials, a 3kW or 6kW laser welding machine would be appropriate.
Production Volume
If your business operates at high volumes, automated systems like robotic arm-based or platform automatic laser welders will provide the speed and consistency needed. On the other hand, for lower-volume, more flexible production, a handheld system might be sufficient.
Application
Consider your specific application. Do you need portability or automation? Handheld systems are perfect for flexible, on-site repairs, while robotic arms and platform systems are best for large-scale production.
| Consideration | Recommendation |
|---|---|
| Power Output | 1.5kW for small parts, 6kW for heavy-duty applications |
| Material Type | Higher power for thick materials |
| Production Volume | Automated systems for high volume |
| Application | Handheld for flexibility, robotic for automation |
