When selecting large fiber laser, always prioritize the laser source brand (JPT/Raycus) over raw wattage for long-term reliability.
Large Fiber Laser: OEM & Customization
At Klear Laser we treat every 6 kW large fiber laser welder as a blank sheet. The chassis starts as a modular steel frame that we stretch, widen, or raise so the gantry clears your jigs, fixtures, and robot seventh-axis rails without forcing you to redesign the line. We then move the cable entry, add forklift pockets, and swap the standard caster set for shock-absorbing feet when the machine has to ride on an AGV.
Software is rewritten around your PLC brand. Our HMI can publish real-time seam depth, feed speed, and wobble amplitude as tags that your SCADA already understands, so the MES dashboard treats the laser like any other station. When you need traceability we embed a SQLite job log that writes weld maps, laser-on time, and fault codes to your network share every cycle, making PPAP audits one click away.
Power is not simply “6 kW on or off.” We gang two 3 kW JPT modules that can fire independently; this gives you 3 kW for thin aluminum and full 6 kW for 12 mm carbon steel without buying two machines. Each module can derate to 10 % in 1 % steps, letting you hold 0.3 kW on zinc-coated press parts to prevent blow-through while keeping beam quality low enough for a 50 µm fiber.
| Feature | Old GMAW / Plasma | Large Klear Fiber Laser |
|---|---|---|
| Max single-pass penetration | 5 mm (multi-run) | 12 mm stainless, 10 mm aluminum |
| Heat input | 0.8–1.2 kJ/mm | 0.25 kJ/mm at 6 kW, 1 m/min |
| Post-weld cleaning | Grinding, slag removal | None, oxide only |
| Filler wire cost | 1.2 kg wire per meter | 0.1 kg or zero autogenous |
| Energy use | 8 kWh per meter | 1.5 kWh per meter |
| Chassis customization | Fixed, 3rd party | Modular, built to fixture height |
| Software integration | None, external retrofit | Native OPC-UA, SQL logs |
| Power tuning | Stepper taps | 1 % closed-loop PWM |
The same modular philosophy applies to our pulsed large fiber cleaning heads. We slide the scanner out of the standard enclosure and bolt it to a gantry you already own, then re-clock the 200 mm lens to 300 mm so the 2 mJ pulses hit your 3 mm thick ship hull plate at 27 J/cm²—enough to remove salt-corroded paint yet keep the peak irradiance below the 0.4 GW/cm² ablation threshold that would pit the steel.
Key Features & Advantages
Klear Laser defines superiority in large fiber laser systems through the rigorous integration of Tier 1 optical components and beam sources. We engineer our high-power units to withstand the demanding duty cycles required by heavy industry, aerospace, and automotive manufacturing. Our commitment to quality ensures that every machine delivers consistent energy density for critical tasks.
The core of our large fiber laser systems is the beam source, where we exclusively utilize industry-leading JPT MOPA and Raycus modules. For our pulsed cleaning machines, the JPT MOPA source allows for precise pulse width tunability to remove contaminants like rust and oil without thermal damage to the substrate. In our heavy-duty welding configurations, high-wattage Raycus sources provide the continuous wave stability necessary for deep penetration and structural integrity.
Our superiority extends to the optical delivery heads which are calibrated for specific industrial outcomes. The welding guns feature advanced wobble technology that oscillates the beam to stir the weld pool and eliminate porosity in the joint. Conversely, our cleaning heads employ high-speed galvanometer scanning to distribute high-energy pulses evenly across broad surface areas for rapid coating removal.
| Component Feature | Large Pulsed Cleaning System | High-Power CW Welding System |
|---|---|---|
| Laser Source Brand | JPT (MOPA Technology) | Raycus / IPG |
| Beam Delivery Type | Nanosecond High-Peak Pulses | Continuous Wave (CW) |
| Optical Head Tech | 2D/3D Galvanometer Scanning | Dual-Axis Wobble Head |
| Control Parameter | Adjustable Pulse Width & Frequency | Beam Width & Swing Speed |
| Primary Benefit | Non-destructive Substrate Cleaning | Deep Penetration & Gap Bridging |
We design these systems to permanently replace hazardous chemical stripping and inefficient arc welding methods. By controlling the entire optical path from the source generation to the focal point, Klear Laser guarantees a cleaner and more efficient industrial process.
Industrial Applications
Large fiber laser welding systems are critical in automotive manufacturing for structural component assembly. High-power continuous-wave lasers (1kW-6kW) from sources like Raycus enable deep penetration welding of ultra-high-strength steels in vehicle frames. Wobble welding heads precisely control heat input to prevent distortion in thin sheets while achieving single-pass penetration up to 8mm. This replaces MIG welding, reducing post-process grinding and improving joint strength for electric vehicle battery trays.
Aerospace manufacturers deploy large pulsed fiber lasers for precision cleaning of turbine blades and structural alloys. Short pulse widths (100-300ns) remove oxidation and contaminants from titanium and Inconel substrates without thermal damage. The controlled energy delivery prevents subsurface microcracking critical for flight-critical parts. This eliminates chemical stripping methods that create hazardous waste streams during maintenance overhauls.
Marine industry applications focus on heavy-duty laser cleaning for ship hull maintenance. High-power pulsed systems (500W-2kW) efficiently remove mill scale, rust, and marine growth from carbon steel decks and ballast tanks. Precise parameter control ensures substrate temperature stays below 50°C, preventing hydrogen embrittlement in structural steel. This replaces abrasive blasting, eliminating silica dust hazards and containment costs in dry dock operations.
| Industry | Primary Application | Key Materials | Typical Thickness | Required Power Range |
|---|---|---|---|---|
| Automotive | Structural Welding | UHSS (980MPa+), Aluminum Alloys | 1.2mm – 6mm | 2kW – 6kW CW |
| Aerospace | Precision Cleaning | Titanium, Inconel 718, Composites | Surface Only | 500W – 1500W Pulsed |
| Marine | Rust Removal | Carbon Steel (A36), Corten | 5mm – 25mm | 1kW – 3kW Pulsed |
Marine cleaning requires careful pulse width adjustment to match rust layer thickness while preserving the steel substrate’s integrity. Aerospace welding often uses JPT MOPA lasers for adjustable pulse shaping on reflective materials like aluminum. Automotive production lines integrate robotic fiber laser cells with real-time weld monitoring for consistent joint quality in high-volume assembly.
