In the hot and humid south, rusting of metal materials such as iron plates and carbon steel is a very normal phenomenon. Can rusted steel plates be cut directly with a laser cutter? The answer is, of course: no.
We all know that laser cutting machine is a kind of clay product, but the laser of laser cutting machine is powerless to rust the surface. Because the laser itself cannot be a light source, heat can only be generated if it is absorbed through the surface of a thin workpiece. For non-rusted materials and rusted materials, the laser absorption is very different and the cutting effect is also different.
Taking rust pieces below 5mm as an example, the cutting conditions of the entire uniform rusted plate are better than the uneven rusted plate. Since the absorption laser of the entire uniform rust plate is also uniform, good cutting can be performed. For materials with uneven surface rust, the surface conditions of the material should be uniform before cutting. Of course, if conditions permit, it is recommended to use a grinder to remove rust.
For thick rusted plates, if you cut the rusted plates directly with a laser cutter, it is easy to cause the phenomenon of impervious cutting, poor cutting quality, and even slag splashing, which may cause damage to the protective lenses and even focus lenses The ceramic body bursts. Therefore, if cutting thick rusty materials, you must first remove the rust and then cut.
