How to Choose a Laser Welder?
FAQ 2021-07-13
1. What is the most important factor when choosing a laser welder?
The two most important factors are material thickness and usage scenario. Material thickness determines the required laser power, while the application scenario determines whether you need a handheld, workstation, or automated laser welding system.
2. How does material thickness affect laser welder selection?
Laser power must match the thickness of the material to ensure proper penetration and weld strength.
- 0.5–3 mm: Low to medium power laser welders are suitable for thin sheet metal and precision parts.
- 3–6 mm: Medium power laser welders are ideal for general fabrication and industrial components.
- 6 mm and above: High-power laser welders are recommended for structural parts and heavy-duty welding.
Choosing insufficient power may cause weak welds, while excessive power can lead to burn-through on thin materials.
3. Can one laser welder handle different thicknesses?
Yes. Most modern laser welders offer adjustable power settings, allowing them to handle a range of thicknesses. However, the base laser power should always be selected according to the most common thickness used in daily production.
4. How does the welding scenario influence the choice?
- Handheld laser welding: Best for flexible jobs, repairs, small batches, and irregular workpieces.
- Workshop or production welding: Suitable for repeated welding of standard parts with consistent thickness.
- Industrial or heavy-duty welding: Requires higher power, stable cooling, and often automated systems for continuous operation.
5. Does material type matter in addition to thickness?
Yes. Materials like stainless steel and carbon steel weld easily, while aluminum and copper reflect more laser energy and usually require higher power or optimized parameters, even at the same thickness.
6. Is higher laser power always better?
No. Higher power increases penetration but also raises cost and the risk of overheating thin materials. The best choice is a laser welder that matches your actual thickness range and application needs, not simply the highest wattage available.
7. What other features should I consider?
In addition to laser power, consider:
- Cooling system stability
- Welding head control and ergonomics
- Safety features and ease of operation
- Suitability for continuous or intermittent use
These factors directly affect long-term welding quality and productivity.
Summary
To choose the right laser welder, start with material thickness, then match it with your welding scenario. A properly selected laser welder delivers stable penetration, clean welds, and higher efficiency without unnecessary cost.
