Laser cut mild steel can be used for a multitude of different applications in engineering and general fabrication. Some of the areas to consider when using GF Laser for laser cutting mild steel are:

1. Material Thickness:
Laser cutting is suitable for a range of material thicknesses. The thickness of the mild steel will affect the power and speed settings of the laser cutter. Thicker materials may require more power and slower cutting speeds, hence thicker laser cut mild steel will be more expensive.

2. Laser Power:
The laser power determines how effectively the material is cut. Higher power is generally required for thicker materials. However, it’s essential to balance the power to avoid excessive heat affecting the cut quality. When designing laser cut mild steel parts consideration should be given to areas such as hole sizes.

3. Cutting Speed:
Cutting speed is a critical factor. It influences the smoothness of the cut and the amount of heat transferred to the material. Adjusting the cutting speed is necessary for achieving optimal results based on the material thickness. Whilst GF Laser will try to cut as quickly as possible our operators are always mindful about making sure cut quality is maintained even if this means slowing the machine.

4. Assist Gas:
Assist gases, such as oxygen or nitrogen from Air Products, are often used to laser cut mild steel. They help to remove molten metal and debris from the cutting area, preventing the cut edges from becoming rough. The choice of gas depends on the material and the desired cut quality.

5. Focus and Beam Quality:
Proper focusing of the laser beam is crucial for achieving precise cuts. Maintaining a high beam quality ensures clean and accurate cuts as well as regular tape shots. Our laser cutting machines are also regularly serviced by the manufacturer Trumpf.

6. Edge Quality:
Laser cutting can produce high-quality edges with minimal burrs. However, the cutting process can generate some heat-affected zones. Adjusting the parameters and using suitable assist gases can help minimize this effect.

7. Design Considerations:
When designing parts for laser cutting, consider the tolerances and capabilities of the laser cutting machine. Small holes and tight corners may require special attention.

8. Post-Processing:
Depending on the application, you may require additional processing such as press braking, welding or powdercoating. GF Laser have a range of approved suppliers that can provide ancillary services.
