The L5-1500 Laser Welding Machine by DMK is an advanced welding tool powered by 1500W fiber laser technology, designed for precision, efficiency, and versatility. It delivers clean, strong welds on stainless steel, carbon steel, and aluminum (0.5–6 mm thickness) with minimal heat distortion—ideal for medium-sized workpieces in modern manufacturing. Key features include a water-cooled system for continuous operation, a CNC control with LCD interface for easy programming, and a compact design (850 mm × 550 mm × 1200 mm) that enables portability. The machine operates on a 220V / 50Hz single-phase power supply, making it suitable for both workshop and on-site use. Its 0.1–3 mm/s welding speed balances precision and productivity, while energy-efficient performance reduces operational costs.
| Laser Power | 1500W |
Welding Speed | 0.1-3 mm/s |
Cooling System | Water-cooled |
Welding Material | Stainless Steel, Carbon Steel, Aluminum |
Welding Thickness | 0.5 - 6 mm |
Control System | CNC with LCD interface |
Power Supply | 220V / 50Hz / Single-phase |
Dimension | 850mm x 550mm x 1200mm |

The 1500W laser power and focused beam create a small heat-affected zone (HAZ), minimizing material distortion. This ensures clean, strong welds—critical for delicate components (e.g., aerospace parts, electronic enclosures).
Compared to traditional arc welding, the fiber laser system converts more input energy into usable heat, reducing power consumption by up to 30%. This lowers costs and supports sustainable production.
Weighing significantly less than bulkier welding machines, the L5-1500 is easy to transport. Its compact size suits frequent setup changes or on-site tasks (e.g., equipment maintenance, field repairs).
It welds stainless steel, carbon steel, and aluminum (0.5–6 mm thickness), adapting to automotive, aerospace, and sheet metal fabrication needs. No specialized tooling is required for material switches.
The LCD-equipped CNC system simplifies parameter setup (welding speed, power) and real-time monitoring. Operators can adjust settings on the fly, reducing errors and training time.
The L5-1500 Laser Welding Machine serves industries prioritizing precision and flexibility:
Automotive Industry: Welding of frame components, exhaust parts, and electrical enclosures.
Aerospace Manufacturing: Precision joining of lightweight aluminum and stainless steel parts.
Electronics Industry: Welding of metal casings for smartphones, computers, and industrial sensors.
Sheet Metal Fabrication: Assembling custom sheet metal products (e.g., cabinets, brackets).
Equipment Maintenance: On-site repair of industrial machinery (e.g., pumps, valves) without disassembly.
DMK implements rigorous quality checks for the L5-1500:
Component Inspection: Laser sources, cooling systems, and CNC modules are tested for performance and durability.
Pre-Assembly Validation: Optical paths are calibrated to ensure laser focus accuracy, and electrical connections are verified.
Performance Testing: Weld quality (strength, appearance) is assessed across different materials and thicknesses at varying welding speeds (0.1–3 mm/s).
Final Audit: The machine is inspected for safety compliance, dimensional accuracy, and adherence to global laser equipment standards.
It specializes in stainless steel, carbon steel, and aluminum (0.5–6 mm thickness). It can also handle other ferrous metals with minor parameter adjustments.
Yes—the water-cooled system uses standard coolant and requires only monthly fluid checks. It automatically shuts down if temperatures exceed safe levels.
Absolutely—its compact design and single-phase power supply (220V / 50Hz) make it ideal for on-site tasks like machinery repair or construction-site fabrication.
DMK offers a 1-year warranty for the machine, covering defects in components and workmanship. Extended warranties are available for high-use applications.
