3000W Fiber Laser Cutting Limits
Carbon Steel Thickness
You can cut carbon steel up to 20mm thick with a 3000W fiber laser. This power level gives you the ability to handle most common carbon steel sheets and plates. When you cut carbon steel at this thickness, you get clean edges and a smooth finish. You can use this for making machine parts, frames, or construction pieces. If you want to cut thicker carbon steel, you need a higher power laser.
Tip: For the best results, use oxygen as the assist gas when cutting carbon steel. Oxygen helps the laser cut faster and improves the edge quality.
Stainless Steel Thickness
A 3000W fiber laser can cut stainless steel up to 10mm thick. Stainless steel is harder to cut than carbon steel because it reflects more light and has a higher melting point. You can still get precise cuts and good edge quality at this thickness. Many industries use this for kitchen equipment, medical tools, and decorative panels.
You should use nitrogen as the assist gas for stainless steel. Nitrogen keeps the cut edge bright and free from oxidation. This is important if you want a clean, shiny finish.
Aluminum Thickness
You can cut aluminum up to 8mm thick with a 3000W fiber laser. Aluminum reflects laser light more than steel, so it is harder to cut. You need to use the right settings and a clean lens for the best results. Many people use this for making signs, panels, and machine covers.
Note: Use nitrogen as the assist gas for aluminum. Nitrogen helps prevent oxidation and keeps the cut edge smooth.
Thickness Range Overview
Here is a quick summary of the maximum cutting thickness for each material with a 3000W fiber laser:
- Carbon Steel: up to 20mm
- Stainless Steel: up to 10mm
- Aluminum: up to 8mm
| Material | Maximum Thickness (mm) |
|---|---|
| Carbon Steel | 20 |
| Stainless Steel | 10 |
| Aluminum | 8 |
You can see that the 3000W fiber laser works best with carbon steel. It can also handle stainless steel and aluminum, but the maximum thickness is lower. Always check the material type before you start your project. This helps you choose the right settings and get the best results.
Factors Influencing Cutting Thickness
Material Properties
The kind of metal you want to cut is important. Some metals are easier to cut than others. Here are the main things that matter:
- Material type
- Thermal conductivity
- Reflective properties
Metals handle heat in different ways. Aluminum bounces more laser light than steel. So, you need to change the laser settings for a good cut. Copper and brass also reflect a lot of light. You must use special settings for these metals. If a metal moves heat quickly, cutting gets harder.
Tip: Always check how much the material absorbs and reflects light. This helps you pick the best settings for your job.
Assist Gas Choice
The gas you use can change how well you cut. Each gas has its own good points. Here is a table to help you pick the right gas:
| Gas Type | Used For | Purpose |
|---|---|---|
| Nitrogen (N2) | Stainless steel, aluminum, galvanized steel | Makes clean cuts with no oxidation. |
| Oxygen (O2) | Mild steel, carbon steel | Helps cut thicker steel faster. |
| Compressed Air | Mild steel, stainless steel, aluminum (thin sheets) | Saves money and works for general cutting. |
The gas you pick also changes the edge and how thick you can cut. Oxygen lets you cut thick carbon steel fast, but the edges may be rough. Nitrogen gives smooth, shiny edges for stainless steel and aluminum. Compressed air is good for thin sheets and costs less.
Cutting Speed and Settings
You need to set the power and speed just right. To cut thick metal, use more power and slow down. This gives the laser more time to cut. For thin metal, you can go faster and save time.
| Setting Type | Recommendation |
|---|---|
| Power for Thicker | Use more power to cut thick metal well. |
| Speed for Thicker | Go slower so the laser can cut cleanly. |
| Speed for Thinner | Go faster to work quickly and keep quality. |
Note: Always test your settings on scrap metal before you start your main job.
Machine Condition
Your laser machine needs to be in good shape. Clean lenses and mirrors help the laser stay strong. Dirty or worn parts can make cuts worse. Take care of your machine to keep it working well. Check for dust and broken parts before each job. A clean, working machine helps you cut thicker metal safely.

Recommended Settings
To get the best results when cutting thick materials, you need to adjust your settings for each type of metal. Here are some practical tips:
- Change the laser power and cutting speed for each material. Thicker metals need more power and a slower speed.
- Pick the right assist gas. Oxygen works well for carbon steel and gives black edges. Nitrogen keeps stainless steel and aluminum edges bright and clean.
- Adjust the focus position based on the material and its thickness. This helps you get a smooth and precise cut.
Tip: Always test your settings on a small piece before starting your main project.
Quality at Maximum Thickness
When you use a 3000W fiber laser at its maximum thickness, you may notice some quality issues. Watch for these common problems:
- The cut quality can get worse over time if you do not clean the lens.
- Heat from the laser can cause the metal to expand, which affects the cut.
- The laser head needs proper calibration to keep cuts straight and even.
- You may see more burrs or rough edges as you cut thicker materials.
To improve your results:
- Use the right assist gas to reduce roughness and slag.
- Increase the laser power and slow down the speed for thick materials.
- Make sure the laser beam is focused correctly.
- Keep your machine clean and check it often.
- Try cutting in layers for very thick pieces.
Safety Tips
