Лазерно заваряване на различни материали: Практически съвети и настройки

окт. 31, 2025

Recommendations

When using a машина за лазерно заваряване, different materials react differently to heat, light, and energy. To achieve strong, clean, and precise welds, you need to adjust your settings according to the material you’re working with. Here’s a practical guide to help you set up your laser welding machine for various materials.

1. Stainless Steel Welding

Tip: Stainless steel is one of the easiest materials to weld with a laser.

Recommended Power: 1000W–2000W

Key Settings: Medium power, high speed, moderate focus

Technique: Avoid overheating to prevent discoloration or warping. Use argon or nitrogen shielding gas for better surface protection.

2. Carbon Steel Welding

Tip: Carbon steel absorbs laser energy efficiently but is prone to oxidation.

Recommended Power: 1500W–3000W

Key Settings: Slightly higher power, slower speed

Technique: Use a proper shielding gas to reduce oxidation and porosity. Always clean the surface before welding to ensure stable quality.

3. Aluminum Welding

Tip: Aluminum reflects laser light easily, making it harder to weld.

Recommended Power: 2000W–6000W

Key Settings: High power, fast speed, short pulse duration

Technique: Preheat thick plates before welding, and make sure joints fit tightly. Use helium or mixed gas to minimize porosity and improve stability.

4. Copper Welding

Tip: Copper has very high thermal conductivity, so it needs more energy for a solid weld.

Recommended Power: 3000W–8000W

Key Settings: High peak power, precise beam focus

Technique: Keep the laser beam stable and use short pulses to reduce heat diffusion and prevent burn-through.

5. Brass and Galvanized Steel Welding

Tip: These materials can produce gas or fumes during welding–safety first!

Recommended Power: 1500W–4000W

Key Settings: Moderate power, high travel speed

Technique: Ensure proper ventilation and fume extraction. Remove zinc coating before welding whenever possible to reduce spatter and porosity.

General Tips for All Materials

1. Always clean the workpiece surface before welding.

2. Choose the right shielding gas for each metal type.

3. Adjust the focus distance carefully to maintain consistent penetration.

4. Test your parameters on scrap materials before starting production.

Заключение

Different materials require different laser settings–there’s no one-size-fits-all solution. The key is to understand your material’s properties and adjust your power, speed, and gas settings accordingly. With the right setup, your laser welding machine can deliver clean, strong, and efficient welds across a wide range of materials.
