Reasons and Solutions for Edge Burning of Popular Laser Cutting Machines Used by Automobile Charging Cabinet Sheet Metal Manufacturers Reasons and solutions for edge burning in laser cutting machines Today, the sheet metal manufacturer of car charging cabinets will share with you the reasons and solutions for the edge burning of popular laser cutting machines. I hope the following content can help everyone. Car charging cabinet sheet metal manufacturer: analysis of the reasons for edge burning of metal laser cutting machines The reason for edge burning and slag sticking in laser cutting of sheet metal parts: When laser cutting sheet metal parts, a large amount of heat is generated. Generally, the heat generated by cutting will diffuse along the slit into the processed metal plate, obtaining sufficient cooling. When metal laser cutting machines process small holes, the outside of the hole can be fully cooled, but the heat diffusion space inside a single hole is small, and the heat energy is too concentrated, leading to phenomena such as overburning and slag hanging. In addition, in thick plate cutting, the molten metal and heat accumulated on the material surface during perforation can cause auxiliary airflow disorder and excessive heat input, leading to overburning. Car charging cabinet sheet metal manufacturers: How to solve the problem of burning edges and slag hanging Solution to overburning in laser cutting of carbon steel holes: In carbon steel cutting with oxygen as the auxiliary gas, the key to solving the problem lies in how to prevent the generation of oxidation reaction heat. When piercing, auxiliary oxygen cutting is used, and after a delay, auxiliary air or nitrogen cutting is used. This method can process holes in 1/6 thick plates. Pulse cutting conditions with low frequency peak output power can reduce heat output and help optimize cutting conditions. Setting the conditions as a single pulse laser beam, high energy intensity, and low frequency peak output can effectively reduce the accumulation of molten metal on the material surface during the perforation process, effectively stopping heat output. Solution for laser cutting of aluminum alloy and stainless steel: In the processing of such materials, nitrogen gas is used as the auxiliary gas, and there will be no burning phenomenon during cutting. However, due to the high temperature of the material inside the small hole, the phenomenon of internal slag hanging will be more frequent. An effective 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 air as the auxiliary gas, just like when using nitrogen, there will be no overburning, but bottom slagging is easy to occur. Therefore, it is necessary to set the conditions to high auxiliary gas pressure, high peak output, and low-frequency pulse. The above is the reason and solution for laser cutting machine edge burning explained by the sheet metal manufacturer of the car charging cabinet. Do you all understand?
