金属激光切割机加工碳钢

激光切割碳钢在以氧气为辅助气体时,解决烧边问题的关键在于如何抑止氧化反应热的产生。
When oxygen is used as auxiliary gas in laser cutting carbon steel, the key to solve the problem of edge burning is how to restrain the generation of oxidation reaction heat.
解决方法是穿孔时辅助氧气,之后切换为辅助空气或氮气来切割,这种方法可加工上限为1/6厚板的小孔。
The solution is to assist oxygen when piercing, and then switch to auxiliary air or nitrogen to cut. This method can process holes with the upper limit of 1 / 6 thick plate.
另外,低频率、高峰值输出功率的脉冲切割条件,能减少热量输出,优化切割条件。把条件设定为单一脉冲激光束、能量强度大的高峰值输出、低频条件,可减少穿孔过程中熔融金属在材料表面的堆积,减少热量输出,进而避免烧边挂渣等问题实现。
In addition, the pulse cutting conditions with low frequency and high peak output power can reduce the heat output and optimize the cutting conditions. Setting the conditions as single pulse laser beam, high energy peak output and low frequency can reduce the accumulation of molten metal on the surface of the material in the process of piercing, reduce the heat output, and avoid the problems of slag hanging at the edge of burning.

在此类材料加工中,使用的辅助气体是氮气,在切割中不会发生烧边,但是,由于小孔内侧材料的温度很高,内侧的挂渣现象将比较频繁。
In this kind of material processing, the auxiliary gas used is nitrogen, and edge burning will not occur in the cutting. However, due to the high temperature of the material inside the small hole, the phenomenon of slag hanging inside will be more frequent.
可采用增加辅助气体的压力的方法解决,将条件设为高峰值输出、低频率的脉冲条件。辅助气体使用空气时也和使用氮气时一样,是不会发生过烧的,但却很容易在底部出现挂渣,需要将条件设置为高辅助气体压力、高峰值输出、低频率的脉冲条件。
It can be solved by increasing the pressure of auxiliary gas and setting the condition as high peak output and low frequency pulse. When air is used as auxiliary gas, as nitrogen is used, overburning will not occur, but slag is easy to appear at the bottom. It is necessary to set the conditions as high auxiliary gas pressure, high peak output and low frequency pulse conditions.
