Do you frequently encounter the following problems?
1. Purchasing an unstable laser source raises concerns about power degradation, inconsistent weld seams, and the inability to achieve continuous, large-scale production.
2. Although well-known laser sources like the IPG fiber laser source offer stable performance, their fiber laser source price is high and has low profit margins; however, cheaper options carry too much risk.
3. The parameters may be similar, but we don’t know how to select the appropriate power level, whether it’s suitable for our materials, or its process compatibility.
4. What is the equipment compatibility like? Can it be easily integrated into our existing machinery?
5. If problems arise, will the after-sales service be adequate?
No worry, our best fiber laser source can help you solve your problems.
1. We utilize Raycus and MAX fiber lasers and optimize operating parameters and system integration for continuous welding conditions, achieving output power instability of only ±1%–1.5%, ensuring stable output and consistent welding quality over long production cycles.
2. Raycus and MAX fiber laser costs are 20%-50% cheaper than IPG lasers. Raycus offers stable, high-power performance and comprehensive after-sales service; MAX provides better cost-effectiveness for medium- and low-power applications. Both are highly regarded in the international market.
3. We recommend suitable laser power and configurations based on welding materials, process requirements, and actual sample testing, focusing on the actual welding results rather than simply providing a specifications sheet for you to choose from.
4. MAX/Raycus fiber laser sources utilize standardized, universal interfaces, ensuring strong compatibility. They have undergone hundreds of compatibility tests and are perfectly compatible with various mainstream welding heads like Raytools, controllers, and automation systems.
5. We take full system-level responsibility for the configuration, integration, and fiber laser source repair. Our after-sales service responds within 24 hours, providing remote or on-site guidance, professional technical support, and troubleshooting to eliminate all responsibility gaps.

How to Choose the Right Fiber Laser Source for Welding?
- Solutions
- Spanish customer case
Choosing a fiber laser source for welding depends on application, material, and system compatibility, not just power rating or brand.
1. Define the Welding Application
- Handheld laser Welding
Typical power: 800W–2000W
Focus on compact size and stable continuous output
Common choice: Raycus / MAX single-module CW fiber lasers
- Automated or Robotic laser Welding
Typical power: 2000W–6000W
Focus on long-term stability and system integration
Single-module CW lasers provide more consistent output for continuous welding
2. Select Power by Material Thickness
Power should match actual welding requirements, not maximum rating.
- Thin materials (≤1mm): 1500W
- Medium thickness (1–2 mm): 2000W
- Thick materials or high speed: 3000W+
(Generally, for every 1 mm increase in workpiece thickness, the power needs to be increased by 1 kW.)
Raycus and MAX offer stable CW fiber lasers across these power ranges.
3. Match Beam and Fiber Core to the Process
- Smaller fiber cores: higher energy density, deeper penetration
- Larger fiber cores: better process tolerance and stability
Raycus and MAX provide multiple fiber core options for proper welding head matching.
4. Consider Reflection Protection
For aluminum, copper, and other reflective materials, back reflection is a key risk.
Raycus and MAX CW fiber lasers integrate reflection detection and protection to reduce optical damage during welding.
5. Check Control and Integration Compatibility
Raycus and MAX laser sources support standard industrial control methods, allowing easy integration with welding heads, robots, and automation systems.
6. Choose Cooling Based on Duty Cycle
- Air-cooled: compact systems, lower power
- Water-cooled: higher power, long-duty-cycle welding
Both cooling options are available depending on application needs.
Welding Application: Robotic laser welding (Water-cooled)
Material Thickness: 1mm
workpiece material: Aluminum
Fiber laser source power: 2000W MAX laser source(2000W single module cw fiber laser)
