Solve the common problems of laser cutting stainless steel from a technological point of view
2018-02-26
Laser-cut stainless steel melts and evaporates stainless steel with the energy released when the laser beam strikes the steel surface. For the manufacturing industry, which uses stainless steel sheet as the main component, laser cutting of stainless steel is a fast and efficient processing method.
If strictly controlled in the process of laser cutting process parameters, can maintain the good corrosion resistance of such materials. The quality of stainless steel cutting the most important process parameters are cutting speed, laser power, pressure and so on. Specific problems and debugging methods are as follows:
1, a small drop-like rules produce burrs
Possible Causes
(1) the focus is too low
(2) feed rate is too high
Solution
(1) raise the focus
(2) reduce the feed rate
2, both sides have long irregular filamentous burr, the surface of large plates discoloration
Possible Causes
(1) feed rate is too low
(2) the focus is too high
(3) pressure is too low
(4) The material is too hot
Solution
(1) increase the feed rate
(2) reduce the focus
(3) increase the pressure
(4) Cooling material
3, only the edge of the cutting edge to produce long irregular burr
Possible Causes
(1) No nozzle alignment
(2) the focus is too high
(3) pressure is too low
(4) speed is too low
Solution
(1) on the nozzle
(2) reduce the focus
(3) increase the pressure
(4) increase speed
4, the material is discharged from above
Possible Causes
(1) Power is too low
(2) feed rate is too large
(3) the pressure is too high
Solution
When this happens, immediately press the pause button to prevent slag from splashing on the focusing mirror. Increase power Decrease feed rate Decrease air pressure
In addition to the above common problems, yellowing of the cutting edge may also occur
Possible Causes
Nitrogen gas contains oxygen impurities
Solution
Use good quality, high purity nitrogen
