• 金属激光切割发黑的原因?

发黑主要是有两点:

加速度过慢,会让激光束在金属的某一处处于较长时间的停歇,激光束照射在金属钣材上某一点的时间过长,就会将金属钣材切成焦黑了。如果出现这种情况的话,可以调整一下激光切割机的切割速度。

气压不行,光纤激光切割机在切割时,气压将经过高温加热的金属熔渣吹走,这样就形成了切割缝。

如果气压过小,熔渣不容易被吹走,吸附在切口表面,形成一层黑色变质材料;同时,高气压可以一定程度上降低激光束接触切口的热量,热量适中,就不会产生焦黑的现象了。

There are two main reasons for blackening:

If the acceleration is too slow, the laser beam will stop for a long time at a certain place of the metal. If the laser beam irradiates a certain point on the metal sheet for too long, the metal sheet will be cut into charred black. If this happens, you can adjust the cutting speed of the laser cutting machine.

When the fiber laser cutting machine is cutting, the air pressure will blow away the metal slag heated by high temperature, thus forming a cutting seam.

If the air pressure is too small, the slag will not be adsorbed on the surface and will not deteriorate easily; At the same time, high air pressure can reduce the heat of the laser beam contacting the notch to a certain extent. If the heat is moderate, there will be no blackening.
