Burn edge issues that should be noted in sheet metal processing

During the processing of sheet metal, a large amount of heat is usually generated, just like laser cutting, which uses high temperature to achieve the processing goal. However, attention should be paid to the issue of metal burning during this process

This sheet metal processing method can process small holes in 1/6 thick plates. The pulse cutting conditions with low frequency and high peak output power have the characteristic of reducing heat output, which helps to optimize the cutting conditions. Setting the conditions as a single pulse laser beam, high peak energy output, and low frequency conditions can reduce the accumulation of molten metal on the material surface during the perforation process, heat output, and then solve the problem, fully utilizing this sheet metal processing skill

In the sheet metal processing of thick plates, overburning problems can also occur. In this type of data processing, the auxiliary gas used is nitrogen, which will not cause burning during cutting. However, due to the high temperature of the data inside the small hole, the phenomenon of slag hanging on the inside will be more frequent

The solution is to increase the pressure of the auxiliary gas and set the conditions to high peak output and low-frequency pulse conditions. When using auxiliary gas with air, it is the same as when using nitrogen, and there will be no overburning, but it is very simple to have slag hanging at the bottom. The conditions need to be set to high auxiliary gas pressure, low-frequency pulse conditions with high peak output, and other factors to ensure good processing effect
