How MixGas Technology Enhances Fiber Laser Cutting Performance

With ongoing advancements in fiber laser power and the reduction of entry costs, fiber laser cutting systems have become highly competitive. As the demand for high-quality, efficient, and cost-effective cutting solutions increases, innovations like MixGas—a hybrid gas mixture for laser cutting—are addressing industry needs. This cutting-edge technology is particularly effective in handling challenging materials and enhancing overall production profitability.

Key Advantages of MixGas Technology in Fiber Laser Cutting

Blending Nitrogen and Oxygen for Optimal Results

In fiber laser cutting, nitrogen is typically used for high-speed cuts, while oxygen is preferred for achieving superior edge quality. However, both gases have their limitations when used separately. MixGas technology combines nitrogen (N₂) and oxygen (O₂) in a specific ratio, combining the strengths of both gases to achieve faster cutting speeds and enhanced cut quality compared to traditional air or nitrogen-only cutting methods. The higher the laser power, the more substantial the performance gains when MixGas is used.

Significant Performance Improvements: Speed and Quality

Cutting Thickness and Surface Quality

MixGas systems enable cutting of thicker materials, especially carbon steel, with minimal slag or dross. For example, a 6 kW laser using MixGas can cut up to 8mm of carbon steel with minimal burrs, while a 12 kW laser handles up to 16mm. A 20 kW laser is capable of cutting up to 20mm, and a 30 kW laser can cut up to 30mm of carbon steel cleanly. In contrast, pure nitrogen or air cutting at these power levels results in poorer cut quality and is unable to reach these thicknesses.

Cutting Speed Enhancement

MixGas also offers significant speed improvements. For instance, a 6 kW MixGas setup can increase cutting speeds by 175% on 5mm carbon steel. A 12 kW system improves cutting speeds by 284% on 8mm carbon steel, while a 20 kW setup boosts speed by 271% on 12mm carbon steel. A 30 kW system achieves a remarkable 400% increase in cutting speed on 16mm carbon steel. These improvements result in faster processing times, boosting throughput and efficiency.

Lower Gas Pressure Requirements

MixGas cutting operates at lower pressures compared to traditional nitrogen or air cutting, leading to reduced gas consumption. This helps lower operational costs, enhancing the overall cost-effectiveness of fiber laser cutting in high-volume applications.
