Processing thick carbon steel has always required manufacturers to balance cutting quality, productivity, and operating costs. While conventional flame cutting machine remains a common solution for heavy plate fabrication, it often struggles to deliver the precision demanded by today’s manufacturing standards. Plasma cutting machine offers higher speed but introduces challenges such as poor edge quality, excessive noise, and an unfavorable working environment. Pure laser cutting machine provides excellent precision, yet its operating cost increases significantly as material thickness grows.
To bridge these gaps, Han’s Laser developed the LFC Series Laser–Flame Hybrid Cutting Machine, an integrated solution that combines the precision of fiber laser technology with the deep penetration capability of flame cutting. The result is a versatile platform capable of delivering efficient, low-taper cutting across a wide range of carbon steel thicknesses.
Combining Two Cutting Technologies into One Efficient Process
Rather than relying on a single cutting method, the LFC Series leverages the strengths of both laser and flame technologies. Fiber laser provides precise energy concentration for accurate material removal, while flame cutting supplies additional thermal energy to improve penetration in thick sections.
The machine is built on a high-rigidity linear guide platform and integrates Han’s Laser’s proprietary hybrid cutting head, sensor technologies, and advanced CNC control. Together, these technologies provide stable cutting performance across applications that traditionally required multiple processing methods.
By replacing conventional plasma or flame cutting in many heavy plate applications, the system helps manufacturers improve edge quality, increase productivity, and reduce environmental impact.
Designed for Materials from Thin Sheet to Ultra-Thick Plate
One of the defining advantages of the LFC Series is its exceptionally wide processing range.
The system can efficiently process materials from 0.6 mm sheet metal to carbon steel plates exceeding 200 mm in thickness, allowing manufacturers to complete both light-duty and heavy-duty jobs on a single machine.
For demanding applications involving 100 mm carbon steel, the machine delivers stable, repeatable production suitable for batch manufacturing.
Its precision is equally impressive. The LFC Series can produce holes with diameters as small as 40% of the material thickness, making it well suited for complex structural components that require both heavy cutting and fine features.
Compared with conventional laser systems operating at the same power levels—such as 12 kW or 20 kW—the hybrid process offers superior cutting capability, higher efficiency, and improved cut quality on medium and thick carbon steel.
Improving Quality While Reducing Production Costs
As material thickness increases, maintaining cut quality becomes increasingly difficult.
The LFC Series is designed to optimize cutting performance on carbon steel thicker than 40 mm, delivering faster processing speeds while minimizing taper and improving surface finish.

Performance testing demonstrates:
- Double-side taper below 0.2 mm on 40 mm and 90 mm carbon steel
- Single-side taper below 0.2 mm on 120 mm carbon steel
- Piercing times of only 5–15 seconds for 50–100 mm plates
The hybrid process also lowers operating costs compared with pure laser cutting systems of equivalent power while eliminating common flame-cutting issues such as excessive kerf width and heavy oxide slag accumulation along the bottom edge.
Three Cutting Modes in a Single Machine
Manufacturers often process a wide variety of materials and thicknesses, making equipment flexibility increasingly important.
The LFC Series allows operators to switch freely between three processing modes:
Laser Cutting
Optimized for thin and medium-thickness materials requiring high-speed, high-precision cutting.
Suitable for:
- Carbon steel
- Stainless steel
- Aluminum
- Copper
Laser–Flame Hybrid Cutting
Combines laser precision with flame-assisted cutting to improve efficiency and edge quality on medium and thick plates.
Flame Cutting with Laser Assistance
Designed specifically for ultra-thick carbon steel, enabling rapid penetration without conventional preheating.
This multi-mode capability enables a single machine to replace multiple standalone cutting systems, reducing capital investment and maximizing floor space utilization.
Integrated Bevel Cutting for Welding Preparation
The LFC Series also supports precision bevel cutting, allowing common weld preparations—including A, V, X, Y, and K bevels—to be completed directly during the cutting process.
Instead of performing separate cutting, milling, and edge preparation operations, manufacturers can produce finished weld-ready components in a single setup.
Benefits include:
- Shorter production cycles
- Reduced labor requirements
- Lower tooling costs
- Consistent root face geometry
- Excellent dimensional accuracy
- High-quality surfaces ready for precision welding
This capability is especially valuable in industries where weld quality directly affects structural performance.
Heavy-Duty Machine Design for Demanding Applications
Processing large steel plates requires more than cutting power—it demands machine stability.
The LFC Series features a high-rigidity linear guide base combined with an extruded aluminum beam and an adaptive structural connection that maintains motion accuracy during high-speed operation and under heavy loads.
Its modular cutting table is engineered for large workpieces and high load capacities, making the system suitable for demanding industries including:
- Shipbuilding
- Structural steel fabrication
- Heavy equipment manufacturing
- Wind energy
- Offshore engineering
- Construction machinery
- Mining equipment
- Coal mining machinery
The robust mechanical design ensures long-term reliability even under continuous heavy-duty production conditions.
Meeting the Future of Heavy Plate Fabrication
As manufacturers continue pursuing higher productivity, tighter tolerances, and more sustainable production methods, hybrid cutting technologies are becoming an increasingly attractive alternative to conventional processes.
By combining fiber laser precision with the penetration capability of flame cutting, the Han’s Laser LFC Series provides a practical solution for processing medium and ultra-thick carbon steel with greater efficiency, lower operating costs, and improved cut quality.
For manufacturers looking to simplify production, expand processing capacity, and improve competitiveness in heavy plate fabrication, laser–flame hybrid cutting offers a powerful and flexible path forward.
