52 expert answers about laser cutting, tube cutting, welding, and metal products from FANY LASER
A: Fiber laser cutters mainly process metal materials including stainless steel, carbon steel, alloy steel, aluminum alloy, brass, and copper sheets. They are suitable for most industrial metal sheets but NOT for wood, plastic, glass, or other non-metal materials.
A: Thickness depends on laser power. A 1500W machine cuts carbon steel up to 8mm and stainless steel up to 4mm. 3000W: 16mm carbon steel, 8mm stainless. 6000W: 25mm carbon steel, 12mm stainless. 12000W: 40mm carbon steel, 20mm stainless. Higher power models can be customized.
A: With properly adjusted parameters, thin sheets produce virtually no burrs with smooth edges. Thick plates may have slight dross, which is normal and easily removed by light grinding without affecting workpiece precision.
A: Deviations within 0.5mm for thin sheets and 1mm for thick plates are normal kerf loss. Larger deviations are usually caused by incorrect parameters, dirty lenses, rail misalignment, servo parameter errors, or uneven workpiece placement. These can be resolved by calibrating parameters, cleaning optics, and realigning the machine.
A: Common causes include insufficient laser power, excessive cutting speed, incorrect focal position, low assist gas pressure, or dirty lenses. Start by cleaning the protective lens and focusing lens, recalibrating focal length, then matching power and speed to material thickness, and checking gas pressure.
A: Our machines are equipped with built-in back-reflection isolators that effectively prevent return-light damage. When cutting reflective metals, reduce starting power, keep lenses clean, and maintain precise focus. This ensures stable cutting without equipment damage.
A: Positioning accuracy is ±0.03mm, repeat positioning accuracy is ±0.02mm, and small-hole and precision part cutting accuracy reaches 0.05mm. This fully meets the requirements of hardware, sheet metal, and precision machining industries.
A: Yes. The machines are designed for industrial-grade continuous operation. With regular maintenance, proper water cooling, and routine cleaning of components, they can run 24/7 without interruption, ideal for high-volume production.
A: Carbon steel cutting uses oxygen at 0.3-0.8 MPa. Stainless steel and aluminum cutting uses nitrogen at 1.0-2.0 MPa. High-purity gas improves cut surface smoothness and reduces dross formation.
A: Rough cut surfaces are usually caused by insufficient gas purity, focal position deviation, mismatched cutting speed, blocked nozzle, or worn lenses. Solutions include switching to high-purity gas, recalibrating focus, adjusting cutting parameters, and cleaning or replacing the nozzle and lenses.
A: Fiber lasers are more energy-efficient than traditional machines. A 1500W model consumes 3-5 kWh, and a 6000W model consumes 10-15 kWh per hour. Standby power consumption is very low, offering significant energy cost savings over long-term use.
A: First check the main power supply, water cooling system, and emergency stop button. Verify assist gas pressure is adequate. If the error is system-parameter related, restart the machine. For complex errors, contact our after-sales support for remote diagnosis.
A: Under normal conditions with regular cleaning, focusing and protective lenses last 6-12 months. In heavy smoke environments or when frequently cutting reflective materials, inspect every 3-6 months. Replace immediately if burn marks appear or light transmittance decreases.
A: Inspect daily. Clean every 50 operating hours using compressed air. Never use hard tools to scrape the nozzle. Replace immediately if the nozzle is deformed or the bore diameter is worn.
A: Our machines feature an intelligent CNC system with simple operation. We provide free one-on-one training. A complete beginner can master basic cutting, programming, and parameter adjustment within 1-2 days.
A: Laser tube cutters handle stainless steel, carbon steel, aluminum alloy, copper, and other metal tubes. They support round, square, rectangular, oval, and special-shaped tubes, covering standard industrial tube specifications.
A: Standard models support tube diameters from 10-600mm and wall thicknesses from 0.5-20mm. Custom machines can be built for larger diameters and thicker walls.
A: Yes. Laser tube cutters integrate multiple processes in one machine: cutting off, precision drilling, 45-degree bevel cutting, special-shaped slotting, engraving, and hollowing out — all in a single pass.
A: Usually caused by unstable clamping, uneven rotation speed, mismatched power/speed, or very thin walls. Adjust clamping force, optimize cutting parameters, and reduce cutting speed to prevent deformation and minimize burrs.
A: Our tube cutters have automatic material support and anti-vibration clamping. Long tubes remain stable with no swaying. Length cutting accuracy is within ±0.05mm.
A: Yes. Custom clamps can be made for oval, D-shaped, grooved, and other special-shaped metal tubes for precision cutting, drilling, and chamfering.
A: With precise parameter adjustment, the cut end is smooth with minimal burrs. Most parts can be used directly. High-end workpieces may need only light grinding.
A: Custom multi-station models support simultaneous cutting of multiple tubes, significantly improving production efficiency for high-volume standardized processing.
A: No blade wear, no dust pollution, no deformation, higher precision, ability to create complex shapes, faster processing, and significant savings on labor and consumable costs.
A: Reduce laser power, increase cutting speed, and raise assist gas pressure. Use a dedicated thin-wall tube cutting program to prevent burn-through and deformation.
A: Laser welders handle stainless steel, carbon steel, aluminum alloy, galvanized sheet, copper, and other metals. They support butt welding, tube joining, edge welding, lap welding, and spot welding.
A: Minimal heat distortion, smooth and fine weld seams with no porosity, high joint strength, little to no grinding needed. Fast and precise — ideal for precision hardware, tubing, and sheet metal components.
A: Aluminum has high thermal conductivity and oxidizes easily. Use dedicated aluminum welding parameters, clean the oxide layer beforehand, and use high-purity argon shielding gas. This prevents blackening, cracking, and insufficient fusion.
A: Handheld welders are best for large, irregular, or mobile welding tasks. Stationary automatic welders are ideal for small precision parts and high-volume standardized production. Choose based on your workpiece and production volume.
A: The weld seam is smooth and bright. For most applications, no polishing is needed. For appearance-critical work, light polishing achieves a mirror finish.
A: Laser welding has an extremely small heat-affected zone. With dedicated parameters, sheets as thin as 0.5mm can be welded steadily with no deformation, burn-through, or collapse.
A: Yes. With precise alignment and uniform beam distribution, tube butt welds are dense, smooth, and aesthetically formed. Sealing strength and joint integrity meet industry standards.
A: No. Laser welders feature intelligent one-button parameter adjustment. Beginners can operate after a short training session — no professional welding qualification needed.
A: Common causes include poor workpiece fit-up, beam spot deviation, insufficient power, excessive scanning speed, or inadequate shielding gas. Realign the workpiece, adjust parameters, and clean the surface.
A: No. Low energy consumption and no consumable costs (no welding rods or wire). Only a small amount of shielding gas is needed. Long-term costs are significantly lower than traditional TIG or arc welding.
