Precautions for laser cutting of different plates in sheet metal processing.

 Laser cutting is a very common and effective method in sheet metal processing. It uses a high-energy laser beam to cut sheet metal into the desired shape and size. However, when performing laser cutting, we need to take some precautions to ensure a safe and smooth cutting process. This article will introduce some precautions to be aware of when laser cutting different sheet materials.

 First of all, when cutting thin plates, we need to pay attention to controlling the laser cutting speed and power. Due to the fragility of thin plates, excessive cutting speed and power may lead to melting, deformation and even cracks at the cutting edge. Therefore, we need to make reasonable parameter adjustments according to the thickness and type of material to ensure the cutting quality.

 Secondly, for thick plate cutting, we need to ensure that the surface of the material is flat and free of cutting dirt. When the laser beam cuts on the surface, if the surface is uneven or there is cutting dirt, the cutting quality will decrease. Therefore, before cutting thick plates, we need to clean and trim the surface of the material to obtain better cutting results.

 In addition, the cutting of different materials also needs attention. For example, when cutting stainless steel plates, due to the poor thermal conductivity of stainless steel, it is easy to cause the molten pool to be too large, thereby affecting the cutting quality. Therefore, when cutting stainless steel plates, we need to reduce the laser power and increase the cutting speed to control the size of the molten pool.

 Finally, we also need to implement safety measures to ensure the safety of the laser cutting process. High temperature and strong light radiation are generated during laser cutting, so we need to wear proper personal protective equipment, such as protective glasses and protective clothing, to protect our safety. At the same time, the working area also needs to be isolated and warned to prevent accidents.

 Laser cutting is an important and widely used technology in sheet metal processing. However, in order to ensure the quality and safety of the cutting process, we need to pay attention to the characteristics and handling methods of various materials. By following the precautions above, we can better meet the cutting challenges of different materials, improve the quality of cuts, and ensure the safety of operators.
