Design

  • Custom Fixture Design: Tailored to the unique cavity structures and dimensions of fiber laser radiators, ensuring precise positioning during welding.

  • Multi-Axis Synchronization: Handles complex 3D welding trajectories (e.g., curved water channels) with high accuracy.

  • Real-Time Process Monitoring: Integrated sensors track temperature, pressure, and rotation speed, with data logging for quality traceability.

  • User-Friendly Interface: Intuitive controls simplify programming and debugging, reducing training time for operators.

  • Modular Scalability: Easy to upgrade with additional axes or sensors, adapting to evolving radiator design needs.


Features

  • Superior Weld Quality: As a solid-state joining technology, SFW eliminates fusion-related defects such as porosity, cracks, and distortion. This ensures dense, high-strength welds with excellent sealing—vital for maintaining leak-free water channels in fiber laser radiators.

  • Low Heat Input & Minimal Deformation: Welding temperatures remain far below material melting points, significantly reducing heat-affected zones (HAZ) and thermal distortion. This is especially critical for heat-sensitive, precision-critical fiber laser radiator components.

  • High Strength & Fatigue Resistance: Weld strength matches or exceeds that of the base material, with exceptional fatigue performance. This guarantees long-term reliability in continuous operation of fiber laser cooling systems.

  • Versatile Material Compatibility: Efficiently joins aluminum alloys, copper alloys, and even dissimilar metal combinations (e.g., aluminum-copper). This flexibility expands design possibilities for high-efficiency radiators.

  • Eco-Friendly Process: No filler materials, shielding gases, or fluxes are required, minimizing fumes and harmful emissions—aligning with modern green manufacturing standards.

  • Automation & Intelligence: Equipped with advanced automated controls and smart monitoring systems, the equipment ensures stable, controllable welding processes with easy operation.



Advantage

  • Precision Sealing of Water Channels: Ensures leak-free welding of complex internal water pathways, maintaining consistent cooling efficiency for fiber lasers.

  • High-Quality Dissimilar Metal Joining: Reliably connects materials like aluminum fins and copper pipes, optimizing heat transfer in radiators.

  • Batch Production Efficiency: Automation features reduce cycle times, lowering per-unit costs in mass production.

  • Consistent Product Quality: Precise parameter control guarantees uniform weld quality across batches, critical for meeting strict fiber laser component standards.


Applications

Our SFW equipment is widely applied in manufacturing water-cooled radiators for fiber lasers, serving:


  • High-End Laser Systems: Supporting high-power, high-stability fiber lasers with reliable cooling.

  • New Energy Industry: Cooling systems for laser cleaning, cutting, and battery manufacturing equipment.

  • Precision Instrumentation: Laser cooling modules requiring strict heat dissipation and sealing.

  • Medical Devices: Cooling systems for medical lasers and aesthetic laser equipment (where reliability is life-critical).

  • Research Institutions: Prototyping and small-batch production of custom fiber laser cooling units.


FAQ

Q1: How does stir friction welding ensure the tightness of water-cooled radiators?
A1: SFW is a solid-state process where a rotating tool generates frictional heat to plasticize materials, creating a bond without melting. This eliminates porosity or cracks in the weld, resulting in dense, leak-proof joints—essential for maintaining water channel integrity in fiber laser radiators.


Q2: What makes SFW better than traditional welding for fiber laser radiators?
A2: Compared to fusion welding, SFW reduces thermal distortion (critical for precision radiators), avoids fusion defects (e.g., cracks), enables dissimilar material joining (e.g., aluminum-copper), and operates without filler materials or gases—making it more efficient, reliable, and eco-friendly.


Q3: Can your equipment weld radiator materials of different thicknesses?
A3: Yes. By adjusting welding parameters (e.g., tool design, rotation speed) and tooling, our equipment reliably welds varying thicknesses of radiator plates, ensuring consistent joint quality.


Q4: Is the equipment difficult to operate? Do we need specialized technicians?
A4: Our equipment prioritizes automation and user-friendliness. While basic training is required for operation and programming, the intuitive interface and automated functions reduce reliance on highly specialized staff. We provide comprehensive training and technical support.


Q5: Does SFW require special surface treatment for radiators?
A5: SFW is more forgiving than traditional welding—its rotating tool breaks down surface oxides during welding. For optimal results, however, we recommend clean, oil-free surfaces to maximize weld quality.
