Precautions for laser cutting carbon steel

As a common metal material, carbon steel is widely used in various industries, so if you want to process and cut, it must be the first choice for laser cutting machine. However, many people do not understand the use of laser cutting machines, which leads to unexpected situations! What we want to talk about below are the precautions for cutting carbon steel by laser cutting machine.

When laser cutting carbon steel, there are burrs on the workpiece. The possible reasons include: (1) The laser focus position is offset, do the focus position test, and adjust according to the offset of the laser focus; (2) The output power of the laser is not enough, It is necessary to check whether the work of the laser generator is normal. If it is normal, observe whether the output value of the laser control button is correct. If it is not correct, adjust it; (3) The cutting line speed is too slow, and the line speed needs to be increased during operation control; ( 4) The purity of the cutting gas is not enough, and it is necessary to provide high-quality cutting working gas; (5) If the machine tool runs for too long, it needs to be shut down and restarted.

The laser is not completely cut: (1) The selection of the laser nozzle does not match the thickness of the processing plate, replace the nozzle or the processing plate; (2) The laser cutting line speed is too fast, and the operation control is required to reduce the line speed.

When cutting mild steel, abnormal sparks occur. When cutting mild steel normally, the sparks are long, flat, and have less split ends. When abnormal spark occurs, it will affect the smoothness and processing quality of the cutting section of the workpiece. At this time, when other parameters are normal, the following conditions should be considered: (1) The nozzle of the laser head is seriously damaged, and the nozzle should be replaced in time; (2) In the case of no new nozzle replacement, the cutting working gas pressure should be increased; (3) If the thread at the connection between the nozzle and the laser head is loose, immediately stop cutting, check the connection state of the laser head, and re-thread the thread.

The above are the precautions for cutting carbon steel plate and stainless steel plate by laser cutting machine. I hope everyone must pay more attention when cutting! The precautions for different cutting materials are different, and the unexpected situations that occur are also different, and we need to treat them according to the specific situation!
