Can a laser cutter cut rusted steel plates

As we all know, laser cutting machine is now a powerful tool for sheet metal processing. However, in the production process, in a relatively humid environment, materials such as carbon steel and iron plates will rust. So, can a laser cutting machine cut rusted materials? What are the precautions? GoodCut laser sharing is as follows:

First of all, it is not recommended to directly use a laser cutter to cut rusted metal.

Because the laser itself cannot be a light source, the laser will only generate heat after the surface of the processed sheet is absorbed. In the case of rusted or non-rusted material surfaces, the laser absorption is different, and the heat generation is also greatly affected. Generally, cutting rusted sheets will have the following effects:

1. The cutting efficiency of the rust plate will be reduced, the effect will be poor, and the scrap rate will be higher. If possible, reduce the use of rust plates or treat rust plates in use.

2. The biggest damage is actually that the holes will burst when punching and cutting, which will cause pollution to the lens. You can use a grinder to remove rust first. If the plate is not a thick plate, it will have little effect under 5MM, but the quality of the cut product will be affected. , the failure rate is high.

3. The cutting condition of the overall uniform rusted plate will be better than that of the unevenly rusted plate. Because the overall uniformly rusted plate absorbs the laser light evenly, it can perform good cutting. For material processing with uneven rust on the surface, the surface condition of the material should be uniform before cutting.

All in all, when laser cutting sheet metal material, it is best to use a clean board. Even if rusted boards must be used, pay attention to a uniform rust condition. It is recommended to use a sander to remove rust and then cut.
