A 3-in-1 fiber laser machine combines welding, cutting, and marking capabilities into a single system, making it highly efficient for processing steel metal materials. Here are how it works and its key advantages:
1. Key Functions of a 3-in-1 Fiber Laser Machine
Laser Cutting:
Can cut through various steel materials (mild steel, stainless steel, carbon steel) with high precision.
Thickness capacity: Typically up to 20mm (depending on laser power, e.g., 1000W–6000W).
Smooth, burr-free edges with minimal heat-affected zone (HAZ).
Laser Welding:
Ideal for thin to medium-thickness steel sheets (0.1mm–10mm).
High-speed, deep-penetration welding with minimal distortion.
Suitable for stainless steel, carbon steel, and alloy steel.
Laser Marking/Engraving:
Permanently marks steel with logos, serial numbers, or barcodes.
Works via annealing, engraving, or ablation without damaging the material.
2. Advantages of a 3-in-1 Fiber Laser Machine
✅ Cost-Effective – One machine replaces three separate systems.
✅ High Precision – Achieves ±0.1mm accuracy in cutting/welding.
✅ Fast Processing – Fiber lasers operate at high speeds (e.g., 10–50 m/min cutting).
✅ Low Maintenance – No consumables (unlike CO₂ lasers).
✅ Energy Efficient – Higher electro-optical conversion rate (~30%).
3. Applications in Steel Metal Processing
Automotive – Body panels, exhaust systems, chassis welding.
Sheet Metal Fabrication – HVAC, enclosures, brackets.
Industrial Machinery – Precision cutting & welding of steel parts.
Jewelry & Tools – Engraving and fine welding.
4. Recommended Laser Parameters for Steel
| Process | Power (W) | Thickness (mm) | Speed | Gas Assist |
|---|---|---|---|---|
| Cutting | 500–6000 | 0.5–20 | 1–50 m/min | O₂/N₂ |
| Welding | 200–3000 | 0.1–10 | 1–10 m/min | Argon |
| Marking | 20–100 | N/A | 100–1000 mm/s | None |
5. Why Choose Fiber Laser Over CO₂ or Plasma?
⚡ Better for thin to medium steel (faster than CO₂).
⚡ Nozzle-free welding reduces contamination.
⚡ More compact & durable (fiber laser source lasts 100,000+ hours).
