Sheet metal processing should pay attention to the problem of burning edge

In the process of sheet metal processing, there is generally a large amount of heat generation, just like laser cutting, using high temperature to achieve the purpose of processing, but in this process to pay attention to the problem of metal burning edge.

This sheet metal processing method can be used to process 1/6 thick plate holes. The pulse cutting conditions with low frequency and peak output power can reduce the heat output, which is helpful to optimize the cutting conditions. Setting the condition as a single pulse laser beam, high peak output of energy intensity, and low frequency condition can reduce the accumulation of molten metal on the material surface in the perforation process, heat output, and then solve the problem, and make full use of this sheet metal processing skill.

Overburning can also occur in sheet metal processing of thick sheet metal. In this kind of data processing, the auxiliary gas used is nitrogen, in the cut is not the outbreak of burning edge. However, due to the high temperature of the data in the inner side of the hole, the slag hanging phenomenon in the inner side will be more frequent.

The solution is to increase the pressure of the auxiliary gas and set the condition as the pulse condition with peak output and low frequency. When the auxiliary gas is used in air, it is the same as when nitrogen is used. There will be no overburning, but slag hanging at the bottom is very simple. It is necessary to set the conditions for high auxiliary gas pressure, low frequency pulse conditions of peak output, and other factors, so as to make the processing work well.
