1, insufficient laser power: insufficient laser power is one of the main reasons for sparks in the laser cutting process. If the laser power is not enough, there will be incomplete melting of the material and bubble generation when cutting, resulting in too much spark.

2, insufficient gas flow: the role of gas in laser cutting is to blow away the oxides and slag generated in the cutting process to maintain the cutting quality. If the gas flow is insufficient or the pressure is not enough, it will lead to the oxides and slag are not completely removed, resulting in the formation of a large spark.

3, the choice of cutting materials: different materials in laser cutting performance is different, some materials easy to produce sparks, such as cast iron, zirconium alloy and so on. Therefore, attention should be paid to the selection of laser cutting materials.

4, cutting speed is too fast: laser cutting speed is too fast will cause the material near the cutting mouth is not fully heated and ablated, resulting in incomplete melting of the material, resulting in sparks. Therefore, it is necessary to properly reduce the cutting speed when using laser cutting equipment.

5, poor laser beam quality: if the quality of the laser beam is not good, it will lead to uneven temperature distribution near the cutting edge, which will produce sparks. Therefore, when using laser cutting equipment, it is necessary to choose a device with good beam quality.
