In the early period, Oreelaser has sorted out ten common problems of laser cutting carbon steel, this period, we bring common problems in the process of laser cutting stainless steel.

When laser cutting stainless steel, the stainless steel is melted and evaporated by the energy released when the laser beam is irradiated onto the surface of the steel sheet. And it is a fast and effective method to cut stainless steel by laser for the manufacture of stainless steel sheets.


If the laser cutting process parameters are strictly controlled during processing, the corrosion resistance of such materials can be maintained. And the most important process parameters affecting the quality of stainless steel cutting are cutting speed, laser power, and air pressure. Specific problems and debugging methods are as follows:


Produce tiny regular burrs in the shape of drops

Possible causes

Solutions

The focus is too low

Raise the focus

Feed rate is too high

Reduce the feed rate


The two sides produce long irregular burrs, the surface of the board is discolored

Possible causesSolutions

Feed rate is too high

Increase the feed rate

The focus is too high

Reduce the focus

Air pressure is too low

Increase air pressure

The material is too hot

Cooling material


Produce long, irregular burrs only on one side of the cut edge

Possible causesSolutions

Nozzle misalignment

Centering nozzle

The focus is too high

Reduce the focus

Air pressure is too low

Increase air pressure

The speed is too low

Increase speed


Material is discharged from above

Possible causesSolutions

The power is too low

In these cases, press the pause button immediately to prevent slag from splashing onto the focusing mirror, increase power, reduce feed rate, and reduce air pressure

Feed rate is too high

Air pressure is too high


What should I do if the cutting edge is yellow? 


Possible causesSolutions

Nitrogen contains oxygen impurities

Use good quality, high purity nitrogen
