6000W Dual Beam Laser Welding Machine is a high-power fiber laser welding system designed for medium and thick plate welding applications. Different from traditional single-beam laser welding, it uses a core beam and ring beam structure to control penetration depth and molten pool stability separately.
The center beam creates deep penetration, while the ring beam provides preheating and thermal balance around the welding area. This structure helps reduce welding defects and improves weld appearance during long-term industrial operation.

Core-Ring Laser Welding Machine
The core-ring dual beam system uses a center beam and a ring beam to control welding penetration and heat distribution. The center beam delivers high energy density for deep penetration, while the ring beam controls heat around the welding area to stabilize the molten pool.
The center beam provides concentrated laser energy to form a stable keyhole and increase penetration depth. It is suitable for thick plate welding applications requiring strong weld penetration.
The ring beam distributes heat around the weld area to maintain a stable molten pool. It helps improve weld bead formation and reduce welding defects during continuous operation.
| Laser Beam | Function | Welding Effect |
|---|---|---|
| Core Beam | Deep penetration | Stable keyhole, deeper weld |
| Ring Beam | Heat control | Stable molten pool, less spatter |
| Combined Beam | Energy balance | Wider and consistent weld seam |
The core-ring dual beam system combines deep penetration and molten pool control in one welding process, providing stable weld quality for thick plate and industrial welding applications.

| Comparison Item | Dual Beam Laser Welding | Traditional Single Beam Laser Welding |
|---|---|---|
| Beam Structure | The laser is divided into two beams with an adjustable energy ratio. The beams can be arranged side-by-side, in series, or coaxially. | A single focused laser beam concentrates energy on one spot. |
| Molten Pool Characteristics | A larger molten pool with better mixing helps gas escape and improves molten pool stability. | Smaller molten pool with limited mixing effect. |
| Welding Speed | Higher welding speed with improved production efficiency. | Lower welding speed compared with dual beam welding. |
| Porosity Control | Porosity can be reduced by about 38%, resulting in denser weld seams. | Porosity defects are more common, especially in aluminum alloy welding. |
| Crack Control | Helps reduce solidification cracks and hot cracks. | Higher sensitivity to welding cracks. |
| Welding Adaptability | Better adaptability to complex conditions such as assembly gaps and dissimilar material welding. | Requires higher assembly accuracy with limited adaptability. |
| Heat Affected Zone | Dual beam energy distribution provides better heat input control and reduces deformation risk. | Heat input is more concentrated, making deformation control more difficult. |
| Process Stability | More stable keyhole formation, lower plasma fluctuation, and smoother welding process. | Keyhole stability is more affected by welding parameters. |
| Applicable Materials | Suitable for aluminum alloys, copper alloys, highly reflective materials, and dissimilar metal welding. | Suitable for common metals but more difficult for highly reflective materials. |
| Equipment Cost | More complex structure with higher equipment cost. | Lower equipment cost. |
Dual beam laser welding machines offer better energy distribution and molten pool control, resulting in improved weld quality, welding speed, and defect control. They are suitable for industrial welding applications with strict requirements for weld strength and stability.
