The best cutting method of S355J2G1W steel plate

At present, cutting S355J2G1W steel plate with laser cutting machine is the most common processing method. Laser cutting can be used to cut most organic and inorganic materials.
Most metal materials can be cut by laser cutting machine. In addition to some high reflective materials, the requirements for cutting are relatively high. S355J2G1W steel plate can obtain good cutting quality and cutting efficiency through laser cutting.

In the process of cutting S355J2G1W steel plate with laser cutting machine, auxiliary gas is generally needed.
The purity and pressure of the auxiliary gas directly affect the quality of the cross section of the cutting plate, and the purity of the cutting oxygen should be more than 99.6%.

When cutting oxygen purity is high, cutting S355J2G1W steel plate section roughness and quality will be higher, of course, the cutting cost will increase.
The purity of nitrogen should be above 99.5% during cutting. Increasing the purity of nitrogen can ensure that the weld color remains unchanged when cutting S355J2G1W steel plate.
